Collaborative problem-solving has been widely embraced in the classroom instruction of critical thinking, which is regarded as the core of curriculum reform based on key competencies in the field of education as well as a key competence for learners in the 21st century. However, the effectiveness of collaborative problem-solving in promoting students’ critical thinking remains uncertain. This current research presents the major findings of a meta-analysis of 36 pieces of the literature revealed in worldwide educational periodicals during the 21st century to identify the effectiveness of collaborative problem-solving in promoting students’ critical thinking and to determine, based on evidence, whether and to what extent collaborative problem solving can result in a rise or decrease in critical thinking. The findings show that (1) collaborative problem solving is an effective teaching approach to foster students’ critical thinking, with a significant overall effect size (ES = 0.82, z  = 12.78, P  < 0.01, 95% CI [0.69, 0.95]); (2) in respect to the dimensions of critical thinking, collaborative problem solving can significantly and successfully enhance students’ attitudinal tendencies (ES = 1.17, z  = 7.62, P  < 0.01, 95% CI[0.87, 1.47]); nevertheless, it falls short in terms of improving students’ cognitive skills, having only an upper-middle impact (ES = 0.70, z  = 11.55, P  < 0.01, 95% CI[0.58, 0.82]); and (3) the teaching type (chi 2  = 7.20, P  < 0.05), intervention duration (chi 2  = 12.18, P  < 0.01), subject area (chi 2  = 13.36, P  < 0.05), group size (chi 2  = 8.77, P  < 0.05), and learning scaffold (chi 2  = 9.03, P  < 0.01) all have an impact on critical thinking, and they can be viewed as important moderating factors that affect how critical thinking develops. On the basis of these results, recommendations are made for further study and instruction to better support students’ critical thinking in the context of collaborative problem-solving.

Introduction.

Although critical thinking has a long history in research, the concept of critical thinking, which is regarded as an essential competence for learners in the 21st century, has recently attracted more attention from researchers and teaching practitioners (National Research Council, 2012 ). Critical thinking should be the core of curriculum reform based on key competencies in the field of education (Peng and Deng, 2017 ) because students with critical thinking can not only understand the meaning of knowledge but also effectively solve practical problems in real life even after knowledge is forgotten (Kek and Huijser, 2011 ). The definition of critical thinking is not universal (Ennis, 1989 ; Castle, 2009 ; Niu et al., 2013 ). In general, the definition of critical thinking is a self-aware and self-regulated thought process (Facione, 1990 ; Niu et al., 2013 ). It refers to the cognitive skills needed to interpret, analyze, synthesize, reason, and evaluate information as well as the attitudinal tendency to apply these abilities (Halpern, 2001 ). The view that critical thinking can be taught and learned through curriculum teaching has been widely supported by many researchers (e.g., Kuncel, 2011 ; Leng and Lu, 2020 ), leading to educators’ efforts to foster it among students. In the field of teaching practice, there are three types of courses for teaching critical thinking (Ennis, 1989 ). The first is an independent curriculum in which critical thinking is taught and cultivated without involving the knowledge of specific disciplines; the second is an integrated curriculum in which critical thinking is integrated into the teaching of other disciplines as a clear teaching goal; and the third is a mixed curriculum in which critical thinking is taught in parallel to the teaching of other disciplines for mixed teaching training. Furthermore, numerous measuring tools have been developed by researchers and educators to measure critical thinking in the context of teaching practice. These include standardized measurement tools, such as WGCTA, CCTST, CCTT, and CCTDI, which have been verified by repeated experiments and are considered effective and reliable by international scholars (Facione and Facione, 1992 ). In short, descriptions of critical thinking, including its two dimensions of attitudinal tendency and cognitive skills, different types of teaching courses, and standardized measurement tools provide a complex normative framework for understanding, teaching, and evaluating critical thinking.

Cultivating critical thinking in curriculum teaching can start with a problem, and one of the most popular critical thinking instructional approaches is problem-based learning (Liu et al., 2020 ). Duch et al. ( 2001 ) noted that problem-based learning in group collaboration is progressive active learning, which can improve students’ critical thinking and problem-solving skills. Collaborative problem-solving is the organic integration of collaborative learning and problem-based learning, which takes learners as the center of the learning process and uses problems with poor structure in real-world situations as the starting point for the learning process (Liang et al., 2017 ). Students learn the knowledge needed to solve problems in a collaborative group, reach a consensus on problems in the field, and form solutions through social cooperation methods, such as dialogue, interpretation, questioning, debate, negotiation, and reflection, thus promoting the development of learners’ domain knowledge and critical thinking (Cindy, 2004 ; Liang et al., 2017 ).

Collaborative problem-solving has been widely used in the teaching practice of critical thinking, and several studies have attempted to conduct a systematic review and meta-analysis of the empirical literature on critical thinking from various perspectives. However, little attention has been paid to the impact of collaborative problem-solving on critical thinking. Therefore, the best approach for developing and enhancing critical thinking throughout collaborative problem-solving is to examine how to implement critical thinking instruction; however, this issue is still unexplored, which means that many teachers are incapable of better instructing critical thinking (Leng and Lu, 2020 ; Niu et al., 2013 ). For example, Huber ( 2016 ) provided the meta-analysis findings of 71 publications on gaining critical thinking over various time frames in college with the aim of determining whether critical thinking was truly teachable. These authors found that learners significantly improve their critical thinking while in college and that critical thinking differs with factors such as teaching strategies, intervention duration, subject area, and teaching type. The usefulness of collaborative problem-solving in fostering students’ critical thinking, however, was not determined by this study, nor did it reveal whether there existed significant variations among the different elements. A meta-analysis of 31 pieces of educational literature was conducted by Liu et al. ( 2020 ) to assess the impact of problem-solving on college students’ critical thinking. These authors found that problem-solving could promote the development of critical thinking among college students and proposed establishing a reasonable group structure for problem-solving in a follow-up study to improve students’ critical thinking. Additionally, previous empirical studies have reached inconclusive and even contradictory conclusions about whether and to what extent collaborative problem-solving increases or decreases critical thinking levels. As an illustration, Yang et al. ( 2008 ) carried out an experiment on the integrated curriculum teaching of college students based on a web bulletin board with the goal of fostering participants’ critical thinking in the context of collaborative problem-solving. These authors’ research revealed that through sharing, debating, examining, and reflecting on various experiences and ideas, collaborative problem-solving can considerably enhance students’ critical thinking in real-life problem situations. In contrast, collaborative problem-solving had a positive impact on learners’ interaction and could improve learning interest and motivation but could not significantly improve students’ critical thinking when compared to traditional classroom teaching, according to research by Naber and Wyatt ( 2014 ) and Sendag and Odabasi ( 2009 ) on undergraduate and high school students, respectively.

The above studies show that there is inconsistency regarding the effectiveness of collaborative problem-solving in promoting students’ critical thinking. Therefore, it is essential to conduct a thorough and trustworthy review to detect and decide whether and to what degree collaborative problem-solving can result in a rise or decrease in critical thinking. Meta-analysis is a quantitative analysis approach that is utilized to examine quantitative data from various separate studies that are all focused on the same research topic. This approach characterizes the effectiveness of its impact by averaging the effect sizes of numerous qualitative studies in an effort to reduce the uncertainty brought on by independent research and produce more conclusive findings (Lipsey and Wilson, 2001 ).

This paper used a meta-analytic approach and carried out a meta-analysis to examine the effectiveness of collaborative problem-solving in promoting students’ critical thinking in order to make a contribution to both research and practice. The following research questions were addressed by this meta-analysis:

What is the overall effect size of collaborative problem-solving in promoting students’ critical thinking and its impact on the two dimensions of critical thinking (i.e., attitudinal tendency and cognitive skills)?

How are the disparities between the study conclusions impacted by various moderating variables if the impacts of various experimental designs in the included studies are heterogeneous?

This research followed the strict procedures (e.g., database searching, identification, screening, eligibility, merging, duplicate removal, and analysis of included studies) of Cooper’s ( 2010 ) proposed meta-analysis approach for examining quantitative data from various separate studies that are all focused on the same research topic. The relevant empirical research that appeared in worldwide educational periodicals within the 21st century was subjected to this meta-analysis using Rev-Man 5.4. The consistency of the data extracted separately by two researchers was tested using Cohen’s kappa coefficient, and a publication bias test and a heterogeneity test were run on the sample data to ascertain the quality of this meta-analysis.

Data sources and search strategies

There were three stages to the data collection process for this meta-analysis, as shown in Fig. 1 , which shows the number of articles included and eliminated during the selection process based on the statement and study eligibility criteria.

This flowchart shows the number of records identified, included and excluded in the article.

First, the databases used to systematically search for relevant articles were the journal papers of the Web of Science Core Collection and the Chinese Core source journal, as well as the Chinese Social Science Citation Index (CSSCI) source journal papers included in CNKI. These databases were selected because they are credible platforms that are sources of scholarly and peer-reviewed information with advanced search tools and contain literature relevant to the subject of our topic from reliable researchers and experts. The search string with the Boolean operator used in the Web of Science was “TS = (((“critical thinking” or “ct” and “pretest” or “posttest”) or (“critical thinking” or “ct” and “control group” or “quasi experiment” or “experiment”)) and (“collaboration” or “collaborative learning” or “CSCL”) and (“problem solving” or “problem-based learning” or “PBL”))”. The research area was “Education Educational Research”, and the search period was “January 1, 2000, to December 30, 2021”. A total of 412 papers were obtained. The search string with the Boolean operator used in the CNKI was “SU = (‘critical thinking’*‘collaboration’ + ‘critical thinking’*‘collaborative learning’ + ‘critical thinking’*‘CSCL’ + ‘critical thinking’*‘problem solving’ + ‘critical thinking’*‘problem-based learning’ + ‘critical thinking’*‘PBL’ + ‘critical thinking’*‘problem oriented’) AND FT = (‘experiment’ + ‘quasi experiment’ + ‘pretest’ + ‘posttest’ + ‘empirical study’)” (translated into Chinese when searching). A total of 56 studies were found throughout the search period of “January 2000 to December 2021”. From the databases, all duplicates and retractions were eliminated before exporting the references into Endnote, a program for managing bibliographic references. In all, 466 studies were found.

Second, the studies that matched the inclusion and exclusion criteria for the meta-analysis were chosen by two researchers after they had reviewed the abstracts and titles of the gathered articles, yielding a total of 126 studies.

Third, two researchers thoroughly reviewed each included article’s whole text in accordance with the inclusion and exclusion criteria. Meanwhile, a snowball search was performed using the references and citations of the included articles to ensure complete coverage of the articles. Ultimately, 36 articles were kept.

Two researchers worked together to carry out this entire process, and a consensus rate of almost 94.7% was reached after discussion and negotiation to clarify any emerging differences.

Eligibility criteria

Since not all the retrieved studies matched the criteria for this meta-analysis, eligibility criteria for both inclusion and exclusion were developed as follows:

The publication language of the included studies was limited to English and Chinese, and the full text could be obtained. Articles that did not meet the publication language and articles not published between 2000 and 2021 were excluded.

The research design of the included studies must be empirical and quantitative studies that can assess the effect of collaborative problem-solving on the development of critical thinking. Articles that could not identify the causal mechanisms by which collaborative problem-solving affects critical thinking, such as review articles and theoretical articles, were excluded.

The research method of the included studies must feature a randomized control experiment or a quasi-experiment, or a natural experiment, which have a higher degree of internal validity with strong experimental designs and can all plausibly provide evidence that critical thinking and collaborative problem-solving are causally related. Articles with non-experimental research methods, such as purely correlational or observational studies, were excluded.

The participants of the included studies were only students in school, including K-12 students and college students. Articles in which the participants were non-school students, such as social workers or adult learners, were excluded.

The research results of the included studies must mention definite signs that may be utilized to gauge critical thinking’s impact (e.g., sample size, mean value, or standard deviation). Articles that lacked specific measurement indicators for critical thinking and could not calculate the effect size were excluded.

Data coding design

In order to perform a meta-analysis, it is necessary to collect the most important information from the articles, codify that information’s properties, and convert descriptive data into quantitative data. Therefore, this study designed a data coding template (see Table 1 ). Ultimately, 16 coding fields were retained.

The designed data-coding template consisted of three pieces of information. Basic information about the papers was included in the descriptive information: the publishing year, author, serial number, and title of the paper.

The variable information for the experimental design had three variables: the independent variable (instruction method), the dependent variable (critical thinking), and the moderating variable (learning stage, teaching type, intervention duration, learning scaffold, group size, measuring tool, and subject area). Depending on the topic of this study, the intervention strategy, as the independent variable, was coded into collaborative and non-collaborative problem-solving. The dependent variable, critical thinking, was coded as a cognitive skill and an attitudinal tendency. And seven moderating variables were created by grouping and combining the experimental design variables discovered within the 36 studies (see Table 1 ), where learning stages were encoded as higher education, high school, middle school, and primary school or lower; teaching types were encoded as mixed courses, integrated courses, and independent courses; intervention durations were encoded as 0–1 weeks, 1–4 weeks, 4–12 weeks, and more than 12 weeks; group sizes were encoded as 2–3 persons, 4–6 persons, 7–10 persons, and more than 10 persons; learning scaffolds were encoded as teacher-supported learning scaffold, technique-supported learning scaffold, and resource-supported learning scaffold; measuring tools were encoded as standardized measurement tools (e.g., WGCTA, CCTT, CCTST, and CCTDI) and self-adapting measurement tools (e.g., modified or made by researchers); and subject areas were encoded according to the specific subjects used in the 36 included studies.

The data information contained three metrics for measuring critical thinking: sample size, average value, and standard deviation. It is vital to remember that studies with various experimental designs frequently adopt various formulas to determine the effect size. And this paper used Morris’ proposed standardized mean difference (SMD) calculation formula ( 2008 , p. 369; see Supplementary Table S3 ).

Procedure for extracting and coding data

According to the data coding template (see Table 1 ), the 36 papers’ information was retrieved by two researchers, who then entered them into Excel (see Supplementary Table S1 ). The results of each study were extracted separately in the data extraction procedure if an article contained numerous studies on critical thinking, or if a study assessed different critical thinking dimensions. For instance, Tiwari et al. ( 2010 ) used four time points, which were viewed as numerous different studies, to examine the outcomes of critical thinking, and Chen ( 2013 ) included the two outcome variables of attitudinal tendency and cognitive skills, which were regarded as two studies. After discussion and negotiation during data extraction, the two researchers’ consistency test coefficients were roughly 93.27%. Supplementary Table S2 details the key characteristics of the 36 included articles with 79 effect quantities, including descriptive information (e.g., the publishing year, author, serial number, and title of the paper), variable information (e.g., independent variables, dependent variables, and moderating variables), and data information (e.g., mean values, standard deviations, and sample size). Following that, testing for publication bias and heterogeneity was done on the sample data using the Rev-Man 5.4 software, and then the test results were used to conduct a meta-analysis.

Publication bias test

When the sample of studies included in a meta-analysis does not accurately reflect the general status of research on the relevant subject, publication bias is said to be exhibited in this research. The reliability and accuracy of the meta-analysis may be impacted by publication bias. Due to this, the meta-analysis needs to check the sample data for publication bias (Stewart et al., 2006 ). A popular method to check for publication bias is the funnel plot; and it is unlikely that there will be publishing bias when the data are equally dispersed on either side of the average effect size and targeted within the higher region. The data are equally dispersed within the higher portion of the efficient zone, consistent with the funnel plot connected with this analysis (see Fig. 2 ), indicating that publication bias is unlikely in this situation.

This funnel plot shows the result of publication bias of 79 effect quantities across 36 studies.

Heterogeneity test

To select the appropriate effect models for the meta-analysis, one might use the results of a heterogeneity test on the data effect sizes. In a meta-analysis, it is common practice to gauge the degree of data heterogeneity using the I 2 value, and I 2  ≥ 50% is typically understood to denote medium-high heterogeneity, which calls for the adoption of a random effect model; if not, a fixed effect model ought to be applied (Lipsey and Wilson, 2001 ). The findings of the heterogeneity test in this paper (see Table 2 ) revealed that I 2 was 86% and displayed significant heterogeneity ( P  < 0.01). To ensure accuracy and reliability, the overall effect size ought to be calculated utilizing the random effect model.

The analysis of the overall effect size

This meta-analysis utilized a random effect model to examine 79 effect quantities from 36 studies after eliminating heterogeneity. In accordance with Cohen’s criterion (Cohen, 1992 ), it is abundantly clear from the analysis results, which are shown in the forest plot of the overall effect (see Fig. 3 ), that the cumulative impact size of cooperative problem-solving is 0.82, which is statistically significant ( z  = 12.78, P  < 0.01, 95% CI [0.69, 0.95]), and can encourage learners to practice critical thinking.

This forest plot shows the analysis result of the overall effect size across 36 studies.

In addition, this study examined two distinct dimensions of critical thinking to better understand the precise contributions that collaborative problem-solving makes to the growth of critical thinking. The findings (see Table 3 ) indicate that collaborative problem-solving improves cognitive skills (ES = 0.70) and attitudinal tendency (ES = 1.17), with significant intergroup differences (chi 2  = 7.95, P  < 0.01). Although collaborative problem-solving improves both dimensions of critical thinking, it is essential to point out that the improvements in students’ attitudinal tendency are much more pronounced and have a significant comprehensive effect (ES = 1.17, z  = 7.62, P  < 0.01, 95% CI [0.87, 1.47]), whereas gains in learners’ cognitive skill are slightly improved and are just above average. (ES = 0.70, z  = 11.55, P  < 0.01, 95% CI [0.58, 0.82]).

The analysis of moderator effect size

The whole forest plot’s 79 effect quantities underwent a two-tailed test, which revealed significant heterogeneity ( I 2  = 86%, z  = 12.78, P  < 0.01), indicating differences between various effect sizes that may have been influenced by moderating factors other than sampling error. Therefore, exploring possible moderating factors that might produce considerable heterogeneity was done using subgroup analysis, such as the learning stage, learning scaffold, teaching type, group size, duration of the intervention, measuring tool, and the subject area included in the 36 experimental designs, in order to further explore the key factors that influence critical thinking. The findings (see Table 4 ) indicate that various moderating factors have advantageous effects on critical thinking. In this situation, the subject area (chi 2  = 13.36, P  < 0.05), group size (chi 2  = 8.77, P  < 0.05), intervention duration (chi 2  = 12.18, P  < 0.01), learning scaffold (chi 2  = 9.03, P  < 0.01), and teaching type (chi 2  = 7.20, P  < 0.05) are all significant moderators that can be applied to support the cultivation of critical thinking. However, since the learning stage and the measuring tools did not significantly differ among intergroup (chi 2  = 3.15, P  = 0.21 > 0.05, and chi 2  = 0.08, P  = 0.78 > 0.05), we are unable to explain why these two factors are crucial in supporting the cultivation of critical thinking in the context of collaborative problem-solving. These are the precise outcomes, as follows:

Various learning stages influenced critical thinking positively, without significant intergroup differences (chi 2  = 3.15, P  = 0.21 > 0.05). High school was first on the list of effect sizes (ES = 1.36, P  < 0.01), then higher education (ES = 0.78, P  < 0.01), and middle school (ES = 0.73, P  < 0.01). These results show that, despite the learning stage’s beneficial influence on cultivating learners’ critical thinking, we are unable to explain why it is essential for cultivating critical thinking in the context of collaborative problem-solving.

Different teaching types had varying degrees of positive impact on critical thinking, with significant intergroup differences (chi 2  = 7.20, P  < 0.05). The effect size was ranked as follows: mixed courses (ES = 1.34, P  < 0.01), integrated courses (ES = 0.81, P  < 0.01), and independent courses (ES = 0.27, P  < 0.01). These results indicate that the most effective approach to cultivate critical thinking utilizing collaborative problem solving is through the teaching type of mixed courses.

Various intervention durations significantly improved critical thinking, and there were significant intergroup differences (chi 2  = 12.18, P  < 0.01). The effect sizes related to this variable showed a tendency to increase with longer intervention durations. The improvement in critical thinking reached a significant level (ES = 0.85, P  < 0.01) after more than 12 weeks of training. These findings indicate that the intervention duration and critical thinking’s impact are positively correlated, with a longer intervention duration having a greater effect.

Different learning scaffolds influenced critical thinking positively, with significant intergroup differences (chi 2  = 9.03, P  < 0.01). The resource-supported learning scaffold (ES = 0.69, P  < 0.01) acquired a medium-to-higher level of impact, the technique-supported learning scaffold (ES = 0.63, P  < 0.01) also attained a medium-to-higher level of impact, and the teacher-supported learning scaffold (ES = 0.92, P  < 0.01) displayed a high level of significant impact. These results show that the learning scaffold with teacher support has the greatest impact on cultivating critical thinking.

Various group sizes influenced critical thinking positively, and the intergroup differences were statistically significant (chi 2  = 8.77, P  < 0.05). Critical thinking showed a general declining trend with increasing group size. The overall effect size of 2–3 people in this situation was the biggest (ES = 0.99, P  < 0.01), and when the group size was greater than 7 people, the improvement in critical thinking was at the lower-middle level (ES < 0.5, P  < 0.01). These results show that the impact on critical thinking is positively connected with group size, and as group size grows, so does the overall impact.

Various measuring tools influenced critical thinking positively, with significant intergroup differences (chi 2  = 0.08, P  = 0.78 > 0.05). In this situation, the self-adapting measurement tools obtained an upper-medium level of effect (ES = 0.78), whereas the complete effect size of the standardized measurement tools was the largest, achieving a significant level of effect (ES = 0.84, P  < 0.01). These results show that, despite the beneficial influence of the measuring tool on cultivating critical thinking, we are unable to explain why it is crucial in fostering the growth of critical thinking by utilizing the approach of collaborative problem-solving.

Different subject areas had a greater impact on critical thinking, and the intergroup differences were statistically significant (chi 2  = 13.36, P  < 0.05). Mathematics had the greatest overall impact, achieving a significant level of effect (ES = 1.68, P  < 0.01), followed by science (ES = 1.25, P  < 0.01) and medical science (ES = 0.87, P  < 0.01), both of which also achieved a significant level of effect. Programming technology was the least effective (ES = 0.39, P  < 0.01), only having a medium-low degree of effect compared to education (ES = 0.72, P  < 0.01) and other fields (such as language, art, and social sciences) (ES = 0.58, P  < 0.01). These results suggest that scientific fields (e.g., mathematics, science) may be the most effective subject areas for cultivating critical thinking utilizing the approach of collaborative problem-solving.

The effectiveness of collaborative problem solving with regard to teaching critical thinking

According to this meta-analysis, using collaborative problem-solving as an intervention strategy in critical thinking teaching has a considerable amount of impact on cultivating learners’ critical thinking as a whole and has a favorable promotional effect on the two dimensions of critical thinking. According to certain studies, collaborative problem solving, the most frequently used critical thinking teaching strategy in curriculum instruction can considerably enhance students’ critical thinking (e.g., Liang et al., 2017 ; Liu et al., 2020 ; Cindy, 2004 ). This meta-analysis provides convergent data support for the above research views. Thus, the findings of this meta-analysis not only effectively address the first research query regarding the overall effect of cultivating critical thinking and its impact on the two dimensions of critical thinking (i.e., attitudinal tendency and cognitive skills) utilizing the approach of collaborative problem-solving, but also enhance our confidence in cultivating critical thinking by using collaborative problem-solving intervention approach in the context of classroom teaching.

Furthermore, the associated improvements in attitudinal tendency are much stronger, but the corresponding improvements in cognitive skill are only marginally better. According to certain studies, cognitive skill differs from the attitudinal tendency in classroom instruction; the cultivation and development of the former as a key ability is a process of gradual accumulation, while the latter as an attitude is affected by the context of the teaching situation (e.g., a novel and exciting teaching approach, challenging and rewarding tasks) (Halpern, 2001 ; Wei and Hong, 2022 ). Collaborative problem-solving as a teaching approach is exciting and interesting, as well as rewarding and challenging; because it takes the learners as the focus and examines problems with poor structure in real situations, and it can inspire students to fully realize their potential for problem-solving, which will significantly improve their attitudinal tendency toward solving problems (Liu et al., 2020 ). Similar to how collaborative problem-solving influences attitudinal tendency, attitudinal tendency impacts cognitive skill when attempting to solve a problem (Liu et al., 2020 ; Zhang et al., 2022 ), and stronger attitudinal tendencies are associated with improved learning achievement and cognitive ability in students (Sison, 2008 ; Zhang et al., 2022 ). It can be seen that the two specific dimensions of critical thinking as well as critical thinking as a whole are affected by collaborative problem-solving, and this study illuminates the nuanced links between cognitive skills and attitudinal tendencies with regard to these two dimensions of critical thinking. To fully develop students’ capacity for critical thinking, future empirical research should pay closer attention to cognitive skills.

The moderating effects of collaborative problem solving with regard to teaching critical thinking

In order to further explore the key factors that influence critical thinking, exploring possible moderating effects that might produce considerable heterogeneity was done using subgroup analysis. The findings show that the moderating factors, such as the teaching type, learning stage, group size, learning scaffold, duration of the intervention, measuring tool, and the subject area included in the 36 experimental designs, could all support the cultivation of collaborative problem-solving in critical thinking. Among them, the effect size differences between the learning stage and measuring tool are not significant, which does not explain why these two factors are crucial in supporting the cultivation of critical thinking utilizing the approach of collaborative problem-solving.

In terms of the learning stage, various learning stages influenced critical thinking positively without significant intergroup differences, indicating that we are unable to explain why it is crucial in fostering the growth of critical thinking.

Although high education accounts for 70.89% of all empirical studies performed by researchers, high school may be the appropriate learning stage to foster students’ critical thinking by utilizing the approach of collaborative problem-solving since it has the largest overall effect size. This phenomenon may be related to student’s cognitive development, which needs to be further studied in follow-up research.

With regard to teaching type, mixed course teaching may be the best teaching method to cultivate students’ critical thinking. Relevant studies have shown that in the actual teaching process if students are trained in thinking methods alone, the methods they learn are isolated and divorced from subject knowledge, which is not conducive to their transfer of thinking methods; therefore, if students’ thinking is trained only in subject teaching without systematic method training, it is challenging to apply to real-world circumstances (Ruggiero, 2012 ; Hu and Liu, 2015 ). Teaching critical thinking as mixed course teaching in parallel to other subject teachings can achieve the best effect on learners’ critical thinking, and explicit critical thinking instruction is more effective than less explicit critical thinking instruction (Bensley and Spero, 2014 ).

In terms of the intervention duration, with longer intervention times, the overall effect size shows an upward tendency. Thus, the intervention duration and critical thinking’s impact are positively correlated. Critical thinking, as a key competency for students in the 21st century, is difficult to get a meaningful improvement in a brief intervention duration. Instead, it could be developed over a lengthy period of time through consistent teaching and the progressive accumulation of knowledge (Halpern, 2001 ; Hu and Liu, 2015 ). Therefore, future empirical studies ought to take these restrictions into account throughout a longer period of critical thinking instruction.

With regard to group size, a group size of 2–3 persons has the highest effect size, and the comprehensive effect size decreases with increasing group size in general. This outcome is in line with some research findings; as an example, a group composed of two to four members is most appropriate for collaborative learning (Schellens and Valcke, 2006 ). However, the meta-analysis results also indicate that once the group size exceeds 7 people, small groups cannot produce better interaction and performance than large groups. This may be because the learning scaffolds of technique support, resource support, and teacher support improve the frequency and effectiveness of interaction among group members, and a collaborative group with more members may increase the diversity of views, which is helpful to cultivate critical thinking utilizing the approach of collaborative problem-solving.

With regard to the learning scaffold, the three different kinds of learning scaffolds can all enhance critical thinking. Among them, the teacher-supported learning scaffold has the largest overall effect size, demonstrating the interdependence of effective learning scaffolds and collaborative problem-solving. This outcome is in line with some research findings; as an example, a successful strategy is to encourage learners to collaborate, come up with solutions, and develop critical thinking skills by using learning scaffolds (Reiser, 2004 ; Xu et al., 2022 ); learning scaffolds can lower task complexity and unpleasant feelings while also enticing students to engage in learning activities (Wood et al., 2006 ); learning scaffolds are designed to assist students in using learning approaches more successfully to adapt the collaborative problem-solving process, and the teacher-supported learning scaffolds have the greatest influence on critical thinking in this process because they are more targeted, informative, and timely (Xu et al., 2022 ).

With respect to the measuring tool, despite the fact that standardized measurement tools (such as the WGCTA, CCTT, and CCTST) have been acknowledged as trustworthy and effective by worldwide experts, only 54.43% of the research included in this meta-analysis adopted them for assessment, and the results indicated no intergroup differences. These results suggest that not all teaching circumstances are appropriate for measuring critical thinking using standardized measurement tools. “The measuring tools for measuring thinking ability have limits in assessing learners in educational situations and should be adapted appropriately to accurately assess the changes in learners’ critical thinking.”, according to Simpson and Courtney ( 2002 , p. 91). As a result, in order to more fully and precisely gauge how learners’ critical thinking has evolved, we must properly modify standardized measuring tools based on collaborative problem-solving learning contexts.

With regard to the subject area, the comprehensive effect size of science departments (e.g., mathematics, science, medical science) is larger than that of language arts and social sciences. Some recent international education reforms have noted that critical thinking is a basic part of scientific literacy. Students with scientific literacy can prove the rationality of their judgment according to accurate evidence and reasonable standards when they face challenges or poorly structured problems (Kyndt et al., 2013 ), which makes critical thinking crucial for developing scientific understanding and applying this understanding to practical problem solving for problems related to science, technology, and society (Yore et al., 2007 ).

Suggestions for critical thinking teaching

Other than those stated in the discussion above, the following suggestions are offered for critical thinking instruction utilizing the approach of collaborative problem-solving.

First, teachers should put a special emphasis on the two core elements, which are collaboration and problem-solving, to design real problems based on collaborative situations. This meta-analysis provides evidence to support the view that collaborative problem-solving has a strong synergistic effect on promoting students’ critical thinking. Asking questions about real situations and allowing learners to take part in critical discussions on real problems during class instruction are key ways to teach critical thinking rather than simply reading speculative articles without practice (Mulnix, 2012 ). Furthermore, the improvement of students’ critical thinking is realized through cognitive conflict with other learners in the problem situation (Yang et al., 2008 ). Consequently, it is essential for teachers to put a special emphasis on the two core elements, which are collaboration and problem-solving, and design real problems and encourage students to discuss, negotiate, and argue based on collaborative problem-solving situations.

Second, teachers should design and implement mixed courses to cultivate learners’ critical thinking, utilizing the approach of collaborative problem-solving. Critical thinking can be taught through curriculum instruction (Kuncel, 2011 ; Leng and Lu, 2020 ), with the goal of cultivating learners’ critical thinking for flexible transfer and application in real problem-solving situations. This meta-analysis shows that mixed course teaching has a highly substantial impact on the cultivation and promotion of learners’ critical thinking. Therefore, teachers should design and implement mixed course teaching with real collaborative problem-solving situations in combination with the knowledge content of specific disciplines in conventional teaching, teach methods and strategies of critical thinking based on poorly structured problems to help students master critical thinking, and provide practical activities in which students can interact with each other to develop knowledge construction and critical thinking utilizing the approach of collaborative problem-solving.

Third, teachers should be more trained in critical thinking, particularly preservice teachers, and they also should be conscious of the ways in which teachers’ support for learning scaffolds can promote critical thinking. The learning scaffold supported by teachers had the greatest impact on learners’ critical thinking, in addition to being more directive, targeted, and timely (Wood et al., 2006 ). Critical thinking can only be effectively taught when teachers recognize the significance of critical thinking for students’ growth and use the proper approaches while designing instructional activities (Forawi, 2016 ). Therefore, with the intention of enabling teachers to create learning scaffolds to cultivate learners’ critical thinking utilizing the approach of collaborative problem solving, it is essential to concentrate on the teacher-supported learning scaffolds and enhance the instruction for teaching critical thinking to teachers, especially preservice teachers.

Implications and limitations

There are certain limitations in this meta-analysis, but future research can correct them. First, the search languages were restricted to English and Chinese, so it is possible that pertinent studies that were written in other languages were overlooked, resulting in an inadequate number of articles for review. Second, these data provided by the included studies are partially missing, such as whether teachers were trained in the theory and practice of critical thinking, the average age and gender of learners, and the differences in critical thinking among learners of various ages and genders. Third, as is typical for review articles, more studies were released while this meta-analysis was being done; therefore, it had a time limit. With the development of relevant research, future studies focusing on these issues are highly relevant and needed.

Conclusions

The subject of the magnitude of collaborative problem-solving’s impact on fostering students’ critical thinking, which received scant attention from other studies, was successfully addressed by this study. The question of the effectiveness of collaborative problem-solving in promoting students’ critical thinking was addressed in this study, which addressed a topic that had gotten little attention in earlier research. The following conclusions can be made:

Regarding the results obtained, collaborative problem solving is an effective teaching approach to foster learners’ critical thinking, with a significant overall effect size (ES = 0.82, z  = 12.78, P  < 0.01, 95% CI [0.69, 0.95]). With respect to the dimensions of critical thinking, collaborative problem-solving can significantly and effectively improve students’ attitudinal tendency, and the comprehensive effect is significant (ES = 1.17, z  = 7.62, P  < 0.01, 95% CI [0.87, 1.47]); nevertheless, it falls short in terms of improving students’ cognitive skills, having only an upper-middle impact (ES = 0.70, z  = 11.55, P  < 0.01, 95% CI [0.58, 0.82]).

As demonstrated by both the results and the discussion, there are varying degrees of beneficial effects on students’ critical thinking from all seven moderating factors, which were found across 36 studies. In this context, the teaching type (chi 2  = 7.20, P  < 0.05), intervention duration (chi 2  = 12.18, P  < 0.01), subject area (chi 2  = 13.36, P  < 0.05), group size (chi 2  = 8.77, P  < 0.05), and learning scaffold (chi 2  = 9.03, P  < 0.01) all have a positive impact on critical thinking, and they can be viewed as important moderating factors that affect how critical thinking develops. Since the learning stage (chi 2  = 3.15, P  = 0.21 > 0.05) and measuring tools (chi 2  = 0.08, P  = 0.78 > 0.05) did not demonstrate any significant intergroup differences, we are unable to explain why these two factors are crucial in supporting the cultivation of critical thinking in the context of collaborative problem-solving.

Critical thinking refers to deliberately scrutinizing and evaluating theories, concepts, or ideas using reasoned reflection and analysis. The act of thinking critically involves moving beyond simply understanding information by questioning its source, its production, and its presentation in order to expose potential bias or researcher subjectivity [i.e., evidence of being influenced by personal opinions and feelings rather than by external determinants ] . Applying critical thinking to investigating a research problem involves actively challenging basic assumptions and questioning the choices and potential motives underpinning how a study was designed and executed and how the author arrived at particular conclusions or recommended courses of action. Applying critical thinking to writing involves effectively synthesizing information and generating compelling arguments.

Thinking Critically

Applying Critical Thinking to Research and Writing

Professors like to use the term critical thinking; in fact, the idea of being a critical thinker permeates much of higher education writ large. In the classroom, the idea of thinking critically is often mentioned by professors when students ask how they should approach writing a research paper [other approaches your professor might mention include interdisciplinarity, compare and contrast, gendered perspective, global, etc.]. However, critical thinking is more than just an approach to research and writing. It is an acquired skill associated with becoming a complex learner capable of discerning important relationships among the elements of, as well as integrating multiple ways of understanding applied to, the research problem. Critical thinking is a lens through which you holistically interrogate a topic.

Given this, critical thinking encompasses a variety of inter-related connotations applied to writing a college-level research paper:

• Integrated and Multi-Dimensional . Critical thinking is not focused on any one element of research, but instead, is applied holistically throughout the process of identifying the research problem, reviewing the literature, applying methods of analysis, describing the results, discussing their implications, and, if appropriate, offering recommendations for further research. It permeates the entire research endeavor from contemplating what to write about to proofreading the final product.
• Humanizes the Research . Thinking critically can help humanize what is being studied by extending the scope of your analysis beyond the traditional boundaries of prior research. The scope of prior research, for example, could have involved only sampling homogeneous populations, only considered certain factors related to the investigation of a phenomenon, or was limited by the way the study was framed or contextualized. Critical thinking supports opportunities to think about incorporating the experiences of traditionally marginalized groups into the research, leading to a more inclusive and representative examination of the topic.
• Non-Linear . This refers to analyzing a research problem in ways that do not rely on sequential decision-making or rational forms of reasoning. Creative thinking relies on intuitive judgement, flexibility, and unconventional approaches to investigating complex phenomena in order to discover new insights, connections, and potential solutions . Thinking critically involves going back and modifying your thinking as new evidence emerges , perhaps multiple times throughout the research process, and then drawing conclusions from multiple perspectives as a result of questioning initial impressions about the topic.
• Normative . This refers to the idea that critical thinking can be used to challenge prior assumptions in ways that advocate for social justice, equity, and resilience, leading to research having a more transformative and expansive impact. In this respect, critical thinking can be viewed as a method for breaking away from dominant culture norms so as to produce research outcomes that illuminate previously hidden aspects of exploitation and injustice.
• Power Dynamics . Research in the social sciences often includes examining aspects of power and influence, focusing on how it operates, how it can be acquired, and how it can be maintained, thereby shaping social relations, organizations, institutions, and the production and maintenance of knowledge. Thinking critically can reveal how societal structures and forces perpetuate power in ways that marginalizes and oppresses specific groups or communities within the contexts of history , politics, economics, culture, and other factors.
• Reflection . A key component of critical thinking is practicing reflexivity; the act of turning ideas and concepts back onto yourself in order to reveal and clarify your own beliefs, assumptions, and perspectives. Being critically reflexive is important because it can reveal hidden biases you may have that could unintentionally influence how you interpret and validate information. The more reflexive you are, the better able and more comfortable you are in opening yourself up to new modes of understanding.
• Rigorous Questioning . Thinking critically is guided by asking questions that lead to addressing complex principles, theories, concepts, or problems more effectively, and in so doing, help distinguish what is known from from what is not known [or that may be hidden]. Critical thinking involves deliberately framing inquiries not only as hypotheses or axioms, but as a way to apply systematic, disciplined,  in-depth forms of questioning about the research problem and in relation to your positionality as a researcher.
• Social Change . An overarching goal of critical thinking applied to research and writing is to seek to identify and challenge forces of inequality, exploitation, oppression, and marinalization that contribute to maintaining the status quo within institutions of society. This can include, for example, schools, court system, businesses, government agencies, or religious organizations that have been created and maintained through certain ways of thinking within the dominant culture. Thinking critically fosters a sense of awareness and empathy about where social change is needed within the overall research process.

Critical thinking permeates the entire research and writing process. However, it applies in particular to the literature review and discussion sections of your paper. These two sections of a research paper most clearly reflect the external/internal duality of thinking critically.

In reviewing the literature, it is important to reflect upon specific aspects of a study, such as, 1) determining if the research design effectively establishes cause and effect relationships or provides insight into explaining why certain phenomena do or do not occur; 2) assessing whether the method of gathering data or information supports the objectives of your study; and, 3) evaluating if the assumptions used t o arrive at a specific conclusion are evidence-based and relevant to addressing the topic. Critically thinking applies to these elements of reviewing prior research by assessing how each source might perpetuate inequalities or hide the voices of others, thereby, limiting its applicability for understanding the scope of the problem and its impact throughout society.

Critical thinking applies to the discussion section of your paper because this is where you contemplate the results of your study and explain its significance in relation to addressing the research problem. Discussion involves more than just summarizing findings and describing outcomes. It includes deliberately considering the importance of the findings and providing reasoned explanations why your paper helps to fill a gap in the literature or expand knowledge and understanding in ways that inform practice. Critical thinking uses reflection to examine your own beliefs concerning the significance of the results in ways that avoid using biased judgment and decision making.

Using Questions to Enable Critical Thinking

At its most fundamental level, critical thinking is thinking about thinking in ways that improve the effectiveness of your ability to reason, analyze, synthesize, evaluate, and report information and, as a result, it advances deeper explorations of the topic*. From a practical standpoint, critical thinking is an act of introspective self-examination that involves formulating open-ended questions that inspire higher levels of reasoning about a research problem. The purpose of asking questions during the research process is to apply a framework of inquiry that challenges conventional assumptions, scrutinizes the evidence presented, determines how effectively arguments have been supported by that evidence, discerns patterns or trends in the findings, and helps imagine alternative outcomes if new or different factors were introduced.

Below are examples of questions that can stimulate critical thinking:

• Why is this a problem?
• Why does this research problem matter?
• Does the problem matter to everyone or just certain groups?
• How might your perspective change if you were on the other side of the argument?
• What patterns or connections can you see in the results?
• What key factors could have altered the outcomes described in the results?
• What evidence would be needed to support any alternative outcomes?
• Should there be any additional or alternative interpretations of the research outcomes?
• What is the explanation for the cause of an event or phenomenon?
• Why has a particular situation or condition arisen?
• Who will be impacted by the recommendations posed by the author?
• Who might be excluded from the author’s recommendations?
• When and how will you know that the recommendations have worked?
• In what ways can you apply knowledge from this study to new situations?
• What is another way to look at how the study was designed?
• How does the study contradict or confirm your understanding of the research problem?
• Do the outcomes of the study inform your own lived experiences?
• What do you think is the significance of this study and why?
• What are the overall strengths and weakness of this study?

NOTE : Being a critical thinker doesn't just happen. Casting a critical eye on how effectively others have studied a research problem requires developing self-confidence in your own abilities to actively engage with information, to consistently ask how and why questions about the research, and to deliberately analyze arguments and recommendations set forth by the author. Examining critically your own beliefs and feeling about your writing involves a willingness to be comfortable questioning yourself in a way that promotes a strong sense of self-awareness and introspection. Together, these outward and inward looking habits can help improve your critical thinking skills and inform how to effectively research and write a college-level research paper.

Along with the increasing attention to artificial intelligence (AI), renewed emphasis or reflection on human intelligence (HI) is appearing in many places and at multiple levels. One of the foci is critical thinking. Critical thinking is one of four key 21st century skills – communication, collaboration, critical thinking and creativity. Though most people are aware of the value of critical thinking, it lacks emphasis in curricula. In this paper, we present a comprehensive definition of critical thinking that ranges from observation and inquiry to argumentation and reflection. Given a broad conception of critical thinking, a developmental approach beginning with children is suggested as a way to help develop critical thinking habits of mind. The conclusion of this analysis is that more emphasis should be placed on developing human intelligence, especially in young children and with the support of artificial intelligence. While much funding and support goes to the development of artificial intelligence, this should not happen at the expense of human intelligence. Overall, the purpose of this paper is to argue for more attention to the development of human intelligence with an emphasis on critical thinking.

Introduction

In recent decades, advancements in Artificial Intelligence (AI) have developed at an incredible rate. AI has penetrated into people’s daily life on a variety of levels such as smart homes, personalized healthcare, security systems, self-service stores, and online shopping. One notable AI achievement was when AlphaGo, a computer program, defeated the World Go Champion Mr. Lee Sedol in 2016. In the previous year, AlphaGo won in a competition against a professional Go player (Silver et al. 2016 ). As Go is one of the most challenging games, the wins of AI indicated a breakthrough. Public attention has been further drawn to AI since then, and AlphaGo continues to improve. In 2017, a new version of AlphaGo beat Ke Jie, the current world No.1 ranking Go player. Clearly AI can manage high levels of complexity.

Given many changes and multiple lines of development and implement, it is somewhat difficult to define AI to include all of the changes since the 1980s (Luckin et al. 2016 ). Many definitions incorporate two dimensions as a starting point: (a) human-like thinking, and (b) rational action (Russell and Norvig 2009 ). Basically, AI is a term used to label machines (computers) that imitate human cognitive functions such as learning and problem solving, or that manage to deal with complexity as well as human experts.

AlphaGo’s wins against human players were seen as a comparison between artificial and human intelligence. One concern is that AI has already surpassed HI; other concerns are that AI will replace humans in some settings or that AI will become uncontrollable (Epstein 2016 ; Fang et al. 2018 ). Scholars worry that AI technology in the future might trigger the singularity (Good 1966 ), a hypothesized future that the development of technology becomes uncontrollable and irreversible, resulting in unfathomable changes to human civilization (Vinge 1993 ).

The famous theoretical physicist Stephen Hawking warned that AI might end mankind, yet the technology he used to communicate involved a basic form of AI (Cellan-Jones 2014 ). This example highlights one of the basic dilemmas of AI – namely, what are the overall benefits of AI versus its potential drawbacks, and how to move forward given its rapid development? Obviously, basic or controllable AI technologies are not what people are afraid of. Spector et al. 1993 distinguished strong AI and weak AI. Strong AI involves an application that is intended to replace an activity performed previously by a competent human, while weak AI involves an application that aims to enable a less experienced human to perform at a much higher level. Other researchers categorize AI into three levels: (a) artificial narrow intelligence (Narrow AI), (b) artificial general intelligence (General AI), and (c) artificial super intelligence (Super AI) (Siau and Yang 2017 ; Zhang and Xie 2018 ). Narrow AI, sometimes called weak AI, refers to a computer that focus on a narrow task such as AlphaZero or a self-driving car. General AI, sometimes referred to as strong AI, is the simulation of human-level intelligence, which can perform more cognitive tasks as well as most humans do. Super AI is defined by Bostrom ( 1998 ) as “an intellect that is much smarter than the best human brains in practically every field, including scientific creativity, general wisdom and social skills” (p.1).

Although the consequence of singularity and its potential benefits or harm to the human race have been intensely debated, an undeniable fact is that AI is capable of undertaking recursive self-improvement. With the increasing improvement of this capability, more intelligent generations of AI will appear rapidly. On the other hand, HI has its own limits and its development requires continuous efforts and investment from generation to generation. Education is the main approach humans use to develop and improve HI. Given the extraordinary growth gap between AI and HI, eventually AI can surpass HI. However, that is no reason to neglect the development and improvement of HI. In addition, in contrast to the slow development rate of HI, the growth of funding support to AI has been rapidly increasing according to the following comparison of support for artificial and human intelligence.

The funding support for artificial and human intelligence

There are challenges in comparing artificial and human intelligence by identifying funding for both. Both terms are somewhat vague and can include a variety of aspects. Some analyses will include big data and data analytics within the sphere of artificial intelligence and others will treat them separately. Some will include early childhood developmental research within the sphere of support for HI and others treat them separately. Education is a major way of human beings to develop and improve HI. The investments in education reflect the efforts put on the development of HI, and they pale in comparison with investments in AI.

Sources also vary from governmental funding of research and development to business and industry investments in related research and development. Nonetheless, there are strong indications of increased funding support for AI in North America, Europe and Asia, especially in China. The growth in funding for AI around the world is explosive. According to ZDNet, AI funding more than doubled from 2016 to 2017 and more than tripled from 2016 to 2018. The growth in funding for AI in the last 10 years has been exponential. According to Venture Scanner, there are approximately 2500 companies that have raised $60 billion in funding from 3400 investors in 72 different countries (see https://www.slideshare.net/venturescanner/artificial-intelligence-q1-2019-report-highlights ). Areas included in the Venture Scanner analysis included virtual assistants, recommendation engines, video recognition, context-aware computing, speech recognition, natural language processing, machine learning, and more.

The above data on AI funding focuses primarily on companies making products. There is no direct counterpart in the area of HI where the emphasis is on learning and education. What can be seen, however, are trends within each area. The above data suggest exponential growth in support for AI. In contrast, according to the Urban Institute, per-student funding in the USA has been relatively flat for nearly two decades, with a few states showing modest increases and others showing none (see http://apps.urban.org/features/education-funding-trends/ ). Funding for education is complicated due to the various sources. In the USA, there are local, state and federal sources to consider. While that mixture of funding sources is complex, it is clear that federal and state spending for education in the USA experienced an increase after World War II. However, since the 1980s, federal spending for education has steadily declined, and state spending on education in most states has declined since 2010 according to a government report (see https://www.usgovernmentspending.com/education_spending ). This decline in funding reflects the decreasing emphasis on the development of HI, which is a dangerous signal.

Decreased support for education funding in the USA is not typical of what is happening in other countries, according to The Hechinger Report (see https://hechingerreport.org/rest-world-invests-education-u-s-spends-less/ ). For example, in the period of 2010 to 2014, American spending on elementary and high school education declined 3%, whereas in the same period, education spending in the 35 countries in the OECD rose by 5% with some countries experiencing very significant increases (e.g., 76% in Turkey).

Such data can be questioned in terms of how effectively funds are being spent or how poorly a country was doing prior to experiencing a significant increase. However, given the performance of American students on the Program for International Student Assessment (PISA), the relative lack of funding support in the USA is roughly related with the mediocre performance on PISA tests (see https://nces.ed.gov/surveys/pisa/pisa2015/index.asp ). Research by Darling-Hammond ( 2014 ) indicated that in order to improve learning and reduce the achievement gap, systematic government investments in high-need schools would be more effective if the focus was on capacity building, improving the knowledge and skills of educators and the quality of curriculum opportunities.

Though HI could not be simply defined by the performance on PISA test, improving HI requires systematic efforts and funding support in high-need areas as well. So, in the following section, we present a reflection on HI.

Reflection on human intelligence

Though there is a variety of definitions of HI, from the perspective of psychology, according to Sternberg ( 1999 ), intelligence is a form of developing expertise, from a novice or less experienced person to an expert or more experienced person, a student must be through multiple learning (implicit and explicit) and thinking (critical and creative) processes. In this paper, we adopted such a view and reflected on HI in the following section by discussing learning and critical thinking.

What is learning?

We begin with Gagné’s ( 1985 ) definition of learning as characterized by stable and persistent changes in what a person knows or can do. How do humans learn? Do you recall how to prove that the square root of 2 is not a rational number, something you might have learned years ago? The method is intriguing and is called an indirect proof or a reduction to absurdity – assume that the square root of 2 is a rational number and then apply truth preserving rules to arrive at a contradiction to show that the square root of 2 cannot be a rational number. We recommend this as an exercise for those readers who have never encountered that method of learning and proof. (see https://artofproblemsolving.com/wiki/index.php/Proof_by_contradiction ). Yet another interesting method of learning is called the process of elimination, sometimes accredited to Arthur Conan Doyle’s ( 1926 ) in The Adventure of the Blanched Soldier – Sherlock Holmes says to Dr. Watson that the process of elimination “starts upon the supposition that when you have eliminated all which is impossible, that whatever remains, however improbable, must be the truth ” (see https://www.dfw-sherlock.org/uploads/3/7/3/8/37380505/1926_november_the_adventure_of_the_blanched_soldier.pdf ).

The reason to mention Sherlock Holmes early in this paper is to emphasize the role that observation plays in learning. The character Sherlock Holmes was famous for his observation skills that led to his so-called method of deductive reasoning (a process of elimination), which is what logicians would classify as inductive reasoning as the conclusions of that reasoning process are primarily probabilistic rather than certain, unlike the proof of the irrationality of the square root of 2 mentioned previously.

In dealing with uncertainty, it seems necessary to make observations and gather evidence that can lead one to a likely conclusion. Is that not what reasonable people and accomplished detectives do? It is certainly what card counters do at gambling houses; they observe high and low value cards that have already been played in order to estimate the likelihood of the next card being a high or low value card. Observation is a critical process in dealing with uncertainty.

Moreover, humans typically encounter many uncertain situations in the course of life. Few people encounter situations which require resolution using a mathematical proof such as the one with which this article began. Jonassen ( 2000 , 2011 ) argued that problem solving is one of the most important and frequent activities in which people engage. Moreover, many of the more challenging problems are ill-structured in the sense that (a) there is incomplete information pertaining to the situation, or (b) the ideal resolution of the problem is unknown, or (c) how to transform a problematic situation into an acceptable situation is unclear. In short, people are confronted with uncertainty nearly every day and in many different ways. The so called key 21st century skills of communication, collaboration, critical thinking and creativity (the 4 Cs; see http://www.battelleforkids.org/networks/p21 ) are important because uncertainty is a natural and inescapable aspect of the human condition. The 4 Cs are interrelated and have been presented by Spector ( 2018 ) as interrelated capabilities involving logic and epistemology in the form of the new 3Rs – namely, re-examining, reasoning, and reflecting. Re-examining is directly linked to observation as a beginning point for inquiry. The method of elimination is one form of reasoning in which a person engages to solve challenging problems. Reflecting on how well one is doing in the life-long enterprise of solving challenging problems is a higher kind of meta-cognitive activity in which accomplished problem-solvers engage (Ericsson et al. 1993 ; Flavell 1979 ).

Based on these initial comments, a comprehensive definition of critical thinking is presented next in the form of a framework.

A framework of critical thinking

Though there is variety of definitions of critical thinking, a concise definition of critical thinking remains elusive. For delivering a direct understanding of critical thinking to readers such as parents and school teachers, in this paper, we present a comprehensive definition of critical thinking through a framework that includes many of the definitions offered by others. Critical thinking, as treated broadly herein, is a multi-dimensioned and multifaceted human capability. Critical thinking has been interpreted from three perspectives: education, psychology, and epistemology, all of which are represented in the framework that follows.

In a developmental approach to critical thinking, Spector ( 2019 ) argues that critical thinking involves a series of cumulative and related abilities, dispositions and other variables (e.g., motivation, criteria, context, knowledge). This approach proceeds from experience (e.g., observing something unusual) and then to various forms of inquiry, investigation, examination of evidence, exploration of alternatives, argumentation, testing conclusions, rethinking assumptions, and reflecting on the entire process.

Experience and engagement are ongoing throughout the process which proceeds from relatively simple experiences (e.g., direct and immediate observation) to more complex interactions (e.g., manipulation of an actual or virtual artifact and observing effects).

The developmental approach involves a variety of mental processes and non-cognitive states, which help a person’s decision making to become purposeful and goal directed. The associated critical thinking skills enable individuals to be likely to achieve a desired outcome in a challenging situation.

In the process of critical thinking, apart from experience, there are two additional cognitive capabilities essential to critical thinking – namely, metacognition and self-regulation . Many researchers (e.g., Schraw et al. 2006 ) believe that metacognition has two components: (a) awareness and understanding of one’s own thoughts, and (b) the ability to regulate one’s own cognitive processes. Some other researchers put more emphasis on the latter component. For example, Davies ( 2015 ) described metacognition as the capacity to monitor the quality of one’s thinking process, and then to make appropriate changes. However, the American Psychology Association (APA) defines metacognition as an awareness and understanding of one’s own thought with the ability to control related cognitive processes (see https://psycnet.apa.org/record/2008-15725-005 ).

Although the definition and elaboration of these two concepts deserve further exploration, they are often used interchangeably (Hofer and Sinatra 2010 ; Schunk 2008 ). Many psychologists see the two related capabilities of metacognition and self-regulation as being closely related - two sides on one coin, so to speak. Metacognition involves or emphasizes awareness, whereas self-regulation involves and emphasizes appropriate control. These two concepts taken together enable a person to create a self-regulatory mechanism, which monitors and regulates the corresponding skills (e.g., observation, inquiry, interpretation, explanation, reasoning, analysis, evaluation, synthesis, reflection, and judgement).

As to the critical thinking skills, it should be noted that there is much discussion about the generalizability and domain specificity of them, just as there is about problem-solving skills in general (Chi et al. 1982 ; Chiesi et al. 1979 ; Ennis 1989 ; Fischer 1980 ). The research supports the notion that to achieve high levels of expertise and performance, one must develop high levels of domain knowledge. As a consequence, becoming a highly effective critical thinker in a particular domain of inquiry requires significant domain knowledge. One may achieve such levels in a domain in which one has significant domain knowledge and experience but not in a different domain in which one has little domain knowledge and experience. The processes involved in developing high levels of critical thinking are somewhat generic. Therefore, it is possible to develop critical thinking in nearly any domain when the two additional capabilities of metacognition and self-regulation are coupled with motivation and engagement and supportive emotional states (Ericsson et al. 1993 ).

Consequently, the framework presented here (see Fig. 1 ) is built around three main perspectives about critical thinking (i.e., educational, psychological and epistemological) and relevant learning theories. This framework provides a visual presentation of critical thinking with four dimensions: abilities (educational perspective), dispositions (psychological perspective), levels (epistemological perspective) and time. Time is added to emphasize the dynamic nature of critical thinking in terms of a specific context and a developmental approach.

Critical thinking often begins with simple experiences such as observing a difference, encountering a puzzling question or problem, questioning someone’s statement, and then leads, in some instances to an inquiry, and then to more complex experiences such as interactions and application of higher order thinking skills (e.g., logical reasoning, questioning assumptions, considering and evaluating alternative explanations).

If the individual is not interested in what was observed, an inquiry typically does not begin. Inquiry and critical thinking require motivation along with an inquisitive disposition. The process of critical thinking requires the support of corresponding internal indispositions such as open-mindedness and truth-seeking. Consequently, a disposition to initiate an inquiry (e.g., curiosity) along with an internal inquisitive disposition (e.g., that links a mental habit to something motivating to the individual) are both required (Hitchcock 2018 ). Initiating dispositions are those that contribute to the start of inquiry and critical thinking. Internal dispositions are those that initiate and support corresponding critical thinking skills during the process. Therefore, critical thinking dispositions consist of initiating dispositions and internal dispositions. Besides these factors, critical thinking also involves motivation. Motivation and dispositions are not mutually exclusive, for example, curiosity is a disposition and also a motivation.

Critical thinking abilities and dispositions are two main components of critical thinking, which involve such interrelated cognitive constructs as interpretation, explanation, reasoning, evaluation, synthesis, reflection, judgement, metacognition and self-regulation (Dwyer et al. 2014 ; Davies 2015 ; Ennis 2018 ; Facione 1990 ; Hitchcock 2018 ; Paul and Elder 2006 ). There are also some other abilities such as communication, collaboration and creativity, which are now essential in current society (see https://en.wikipedia.org/wiki/21st_century_skills ). Those abilities along with critical thinking are called the 4Cs; they are individually monitored and regulated through metacognitive and self-regulation processes.

The abilities involved in critical thinking are categorized in Bloom’s taxonomy into higher order skills (e.g., analyzing and synthesizing) and lower level skills (e.g., remembering and applying) (Anderson and Krathwohl 2001 ; Bloom et al. 1956 ).

The thinking process can be depicted as a spiral through both lower and higher order thinking skills. It encompasses several reasoning loops. Some of them might be iterative until a desired outcome is achieved. Each loop might be a mix of higher order thinking skills and lower level thinking skills. Each loop is subject to the self-regulatory mechanism of metacognition and self-regulation.

But, due to the complexity of human thinking, a specific spiral with reasoning loops is difficult to represent. Therefore, instead of a visualized spiral with an indefinite number of reasoning loops, the developmental stages of critical thinking are presented in the diagram (Fig. 1 ).

Besides, most of the definitions of critical thinking are based on the imagination about ideal critical thinkers such as the consensus generated from the Delphi report (Facione 1990 ). However, according to Dreyfus and Dreyfus ( 1980 ), in the course of developing an expertise, students would pass through five stages. Those five stages are “absolute beginner”, “advanced beginner”, “competent performer”, “proficient performer,” and “intuitive expert performer”. Dreyfus and Dreyfus ( 1980 ) described the five stages the result of the successive transformations of four mental functions: recollection, recognition, decision making, and awareness.

In the course of developing critical thinking and expertise, individuals will pass through similar stages which are accompanied with the increasing practices and accumulation of experience. Through the intervention and experience of developing critical thinking, as a novice, tasks are decomposed into context-free features which could be recognized by students without the experience of particular situations. For further improving, students need to be able to monitor their awareness, and with a considerable experience. They can note recurrent meaningful component patterns in some contexts. Gradually, increased practices expose students to a variety of whole situations which enable the students to recognize tasks in a more holistic manner as a professional. On the other hand, with the increasing accumulation of experience, individuals are less likely to depend simply on abstract principles. The decision will turn to something intuitive and highly situational as well as analytical. Students might unconsciously apply rules, principles or abilities. A high level of awareness is absorbed. At this stage, critical thinking is turned into habits of mind and in some cases expertise. The description above presents a process of critical thinking development evolving from a novice to an expert, eventually developing critical thinking into habits of mind.

We mention the five-stage model proposed by Dreyfus and Dreyfus ( 1980 ) to categorize levels of critical thinking and emphasize the developmental nature involved in becoming a critical thinker. Correspondingly, critical thinking is categorized into 5 levels: absolute beginner (novice), advanced beginner (beginner), competent performer (competent), proficient performer (proficient), and intuitive expert (expert).

Ability level and critical thinker (critical thinking) level together represent one of the four dimensions represented in Fig. 1 .

In addition, it is noteworthy that the other two elements of critical thinking are the context and knowledge in which the inquiry is based. Contextual and domain knowledge must be taken into account with regard to critical thinking, as previously argued. Besides, as Hitchcock ( 2018 ) argued, effective critical thinking requires knowledge about and experience applying critical thinking concepts and principles as well.

Critical thinking is considered valuable across disciplines. But except few courses such as philosophy, critical thinking is reported lacking in most school education. Most of researchers and educators thus proclaim that integrating critical thinking across the curriculum (Hatcher 2013 ). For example, Ennis ( 2018 ) provided a vision about incorporating critical thinking across the curriculum in higher education. Though people are aware of the value of critical thinking, few of them practice it. Between 2012 and 2015, in Australia, the demand of critical thinking as one of the enterprise skills for early-career job increased 125% (Statista Research Department, 2016). According to a survey across 1000 adults by The Reboot Foundation 2018 , more than 80% of respondents believed that critical thinking skills are lacking in today’s youth. Respondents were deeply concerned that schools do not teach critical thinking. Besides, the investigation also found that respondents were split over when and how to teach critical thinking, clearly.

In the previous analysis of critical thinking, we presented the mechanism of critical thinking instead of a concise definition. This is because, given the various perspectives of interpreting critical thinking, it is not easy to come out with an unitary definition, but it is essential for the public to understand how critical thinking works, the elements it involves and the relationships between them, so they can achieve an explicit understanding.

In the framework, critical thinking starts from simple experience such as observing a difference, then entering the stage of inquiry, inquiry does not necessarily turn the thinking process into critical thinking unless the student enters a higher level of thinking process or reasoning loops such as re-examining, reasoning, reflection (3Rs). Being an ideal critical thinker (or an expert) requires efforts and time.

According to the framework, simple abilities such as observational skills and inquiry are indispensable to lead to critical thinking, which suggests that paying attention to those simple skills at an early stage of children can be an entry point to critical thinking. Considering the child development theory by Piaget ( 1964 ), a developmental approach spanning multiple years can be employed to help children develop critical thinking at each corresponding development stage until critical thinking becomes habits of mind.

Although we emphasized critical thinking in this paper, for the improvement of intelligence, creative thinking and critical thinking are separable, they are both essential abilities that develop expertise, eventually drive the improvement of HI at human race level.

As previously argued, there is a similar pattern among students who think critically in different domains, but students from different domains might perform differently in creativity because of different thinking styles (Haller and Courvoisier 2010 ). Plus, students have different learning styles and preferences. Personalized learning has been the most appropriate approach to address those differences. Though the way of realizing personalized learning varies along with the development of technologies. Generally, personalized learning aims at customizing learning to accommodate diverse students based on their strengths, needs, interests, preferences, and abilities.

Meanwhile, the advancement of technology including AI is revolutionizing education; students’ learning environments are shifting from technology-enhanced learning environments to smart learning environments. Although lots of potentials are unrealized yet (Spector 2016 ), the so-called smart learning environments rely more on the support of AI technology such as neural networks, learning analytics and natural language processing. Personalized learning is better supported and realized in a smart learning environment. In short, in the current era, personalized learning is to use AI to help learners perform at a higher level making adjustments based on differences of learners. This is the notion with which we conclude – the future lies in using AI to improve HI and accommodating individual differences.

The application of AI in education has been a subject for decades. There are efforts heading to such a direction though personalized learning is not technically involved in them. For example, using AI technology to stimulate critical thinking (Zhu 2015 ), applying a virtual environment for building and assessing higher order inquiry skills (Ketelhut et al. 2010 ). Developing computational thinking through robotics (Angeli and Valanides 2019 ) is another such promising application of AI to support the development of HI.

However, almost all of those efforts are limited to laboratory experiments. For accelerating the development rate of HI, we argue that more emphasis should be given to the development of HI at scale with the support of AI, especially in young children focusing on critical and creative thinking.

In this paper, we argue that more emphasis should be given to HI development. Rather than decreasing the funding of AI, the analysis of progress in artificial and human intelligence indicates that it would be reasonable to see increased emphasis placed on using various AI techniques and technologies to improve HI on a large and sustainable scale. Well, most researchers might agree that AI techniques or the situation might be not mature enough to support such a large-scale development. But it would be dangerous if HI development is overlooked. Based on research and theory drawn from psychology as well as from epistemology, the framework is intended to provide a practical guide to the progressive development of inquiry and critical thinking skills in young children as children represent the future of our fragile planet. And we suggested a sustainable development approach for developing inquiry and critical thinking (See, Spector 2019 ). Such an approach could be realized through AI and infused into HI development. Besides, a project is underway in collaboration with NetDragon to develop gamified applications to develop the relevant skills and habits of mind. A game-based assessment methodology is being developed and tested at East China Normal University that is appropriate for middle school children. The intention of the effort is to refocus some of the attention on the development of HI in young children.

Organized in 11 parts, this his textbook includes introductory information about critical thinking and details about the academic research process. The basics of critical thinking related to doing academic research in Parts I and II. Parts III – XI provide specifics on various steps in doing academic research including details on finding and citing source material. There is a linked table of contents so the reader is able to jump to a specific section as needed. There is also a works cited page with information and links to works used for this textbook.

Content Accuracy rating: 5

The content of this textbook is accurate and error free. It contains examples that demonstrate concepts from a variety of disciplines such as “hard science” or “popular culture” that assist in eliminating bias. The authors are librarians so it is clear that their experience as such leads to clear and unbiased content.

Relevance/Longevity rating: 5

General concepts about critical thinking and academic research methodology is well defined and should not become obsolete. Specific content regarding use of citation tools and attribution structure may change but the links to various research sites allow for simple updates.

Clarity rating: 5

This textbook is written in a conversational manner that allows for a more personal interaction with the textbook. It is like the reader is having a conversation with a librarian. Each part has an introduction section that fully defines concepts and terms used for that part.

Consistency rating: 5

In addition to the written content, this textbook contains links to short quizzes at the end of each section. This is consistent throughout each part. Embedded links to additional information are included as necessary.

Modularity rating: 4

This textbook is arranged in 11 modular parts with each part having multiple sections. All of these are linked so a reader can go to a distinct part or section to find specific information. There are some links that refer back to previous sections in the document. It can be challenging to return to where you were once you have jumped to a different section.

Organization/Structure/Flow rating: 5

There is clear definition as to what information is contained within each of the parts and subsequent sections. The textbook follows the logical flow of the process of researching and writing a research paper.

Interface rating: 4

The pictures have alternative text that appears when you hover over the text. There is one picture on page 102 that is a link to where the downloaded picture is from. The pictures are clear and supportive of the text for a visual learner. All the links work and go to either the correct area of the textbook or to a valid website. If you are going to use the embedded links to go to other sections of the textbook you need to keep track of where you are as it can sometimes get confusing as to where you went based on clicking links.

Grammatical Errors rating: 4

This is not really a grammatical error but I did notice on some of the quizzes if you misspelled a work for fill in the blank it was incorrect. It was also sometimes challenging to come up with the correct word for the fill in the blanks.

Cultural Relevance rating: 5

There are no examples or text that are culturally insensitive or offensive. The examples are general and would be applicable to a variety of students study many different academic subjects. There are references and information to many research tools from traditional such as checking out books and articles from the library to more current such as blogs and other electronic sources. This information appeals to a wide expanse of student populations.

I really enjoyed the quizzes at the end of each section. It is very beneficial to test your knowledge and comprehension of what you just read. Often I had to return and reread the content more critically based on my quiz results! They are just the right length to not disrupt the overall reading of the textbook and cover the important content and learning objectives.

Critical Thinking in Academic Research thoroughly covers the basics of academic research for undergraduates, including well-guided deeper dives into relevant areas. The authors root their introduction to academic research principles and practices in the Western philosophical tradition, focused on developing students' critical thinking skills and habits around inquiry, rationales, and frameworks for research.

This text conforms to the principles and frames of the Framework for Information Literacy for Higher Education, published by the Association of College and Research Libraries. It includes excellent, clear, step-by-step guides to help students understand rationales and techniques for academic research.

Essential for our current information climate, the authors present relevant information for students who may be new to academic research, in ways and with content that is not too broad or too narrow, or likely to change drastically in the near future.

The authors use clear and well-considered language and explanations of ideas and terms, contextualizing the scholarly research process and tools in a relatable manner. As mentioned earlier, this text includes excellent step-by-step guides, as well as illustrations, visualizations, and videos to instruct students in conducting academic research.

(4.75) The terminology and framework of this text are consistent. Early discussions of critical thinking skills are tied in to content in later chapters, with regard to selecting different types of sources and search tools, as well as rationales for choosing various formats of source references. Consciously making the theme of critical thinking as applied to the stages of academic research more explicit and frequent within the text would further strengthen it, however.

Modularity rating: 5

Chapters are divided in a logical, progressive manner throughout the text. The use of embedded links to further readings and some other relevant sections of the text are an excellent way of providing references and further online information, without overwhelming or side-tracking the reader.

Topics in the text are organized in logical, progressive order, transitioning cleanly from one focus to the next. Each chapter begins with a helpful outline of topics that will be covered within it.

There are no technical issues with the interface for this text. Interactive learning tools such as the many self-checks and short quizzes that are included throughout the text are a great bonus for reinforcing student learning, and the easily-accessible table of contents was very helpful. There are some slight inconsistencies across chapters, however, relative to formatting images and text and spacing, and an image was missing in the section on Narrowing a Topic. Justifying copy rather than aligning-left would prevent hyphenation, making the text more streamlined.

Grammatical Errors rating: 5

(4.75) A few minor punctuation errors are present.

The authors of this text use culturally-relevant examples and inclusive language. The chapter on Barriers to Critical Thinking works directly to break down bias and preconceived notions.

Overall, Critical Thinking in Academic Research is an excellent general textbook for teaching the whys and hows of academic research to undergraduates. A discussion of annotated bibliographies would be a great addition for future editions of the text. ---- (As an aside for the authors, I am curious if the anonymous data from the self-checks and quizzes is being collected and analyzed for assessment purposes. I'm sure it would be interesting!)

This book provides a comprehensive yet easily comprehensible introduction to critical thinking in academic research. The author lays a foundation with an introduction to the concepts of critical thinking and analyzing and making arguments, and then moves into the details of developing research questions and identifying and appropriately using research sources. There are many wonderful links to other open access publications for those who wish to read more or go deeper.

The content of the book appears to be accurate and free of bias.

The examples used throughout the book are relevant and up-to-date, making it easy to see how to apply the concepts in real life.

The text is very accessibly written and the content is presented in a simple, yet powerful way that helps the reader grasp the concepts easily. There are many short, interactive exercises scattered throughout each chapter of the book so that the reader can test their own knowledge as they go along. It would be even better if the author had provided some simple feedback explaining why quiz answers are correct or incorrect in order to bolster learning, but this is a very minor point and the interactive exercises still work well without this.

The book appears consistent throughout with regard to use of terminology and tone of writing. The basic concepts introduced in the early chapters are used consistently throughout the later chapters.

This book has been wonderfully designed into bite sized chunks that do not overwhelm the reader. This is perhaps its best feature, as this encourages the reader to take in a bit of information, digest it, check their understanding of it, and then move on to the next concept. I loved this!

The book is organized in a manner that introduces the basic architecture of critical thinking first, and then moves on to apply it to the subject of academic research. While the entire book would be helpful for college students (undergraduates particularly), the earlier chapters on critical thinking and argumentation also stand well on their own and would be of great utility to students in general.

This book was extremely easy to navigate with a clear, drop down list of chapters and subheadings on the left side of the screen. When the reader clicks on links to additional material, these open up in a new tab which keeps things clear and organized. Images and charts were clear and the overall organization is very easy to follow.

I came across no grammatical errors in the text.

Cultural Relevance rating: 4

This is perhaps an area where the book could do a little more. I did not come across anything that seemed culturally insensitive or offensive but on the other hand, the book might have taken more opportunities to represent a greater diversity of races, ethnicities, and backgrounds.

This book seems tailor made for undergraduate college students and I would highly recommend it. I think it has some use for graduate students as well, although some of the examples are perhaps little basic for this purpose. As well as using this book to guide students on doing academic research, I think it could also be used as a very helpful introduction to the concept of critical thinking by focusing solely on chapters 1-4.

More and more often, we hear that higher education should foment critical thinking. The new skills focus for university teaching grants a central role to critical thinking in new study plans; however, using these skills well requires a certain degree of conscientiousness and its regulation. Metacognition therefore plays a crucial role in developing critical thinking and consists of a person being aware of their own thinking processes in order to improve them for better knowledge acquisition. Critical thinking depends on these metacognitive mechanisms functioning well, being conscious of the processes, actions, and emotions in play, and thereby having the chance to understand what has not been done well and correcting it. Even when there is evidence of the relation between metacognitive processes and critical thinking, there are still few initiatives which seek to clarify which process determines which other one, or whether there is interdependence between both. What we present in this study is therefore an intervention proposal to develop critical thinking and meta knowledge skills. In this context, Problem-Based Learning is a useful tool to develop these skills in higher education. The ARDESOS-DIAPROVE program seeks to foment critical thinking via metacognition and Problem-Based Learning methodology. It is known that learning quality improves when students apply metacognition; it is also known that effective problem-solving depends not only on critical thinking, but also on the skill of realization, and of cognitive and non-cognitive regulation. The study presented hereinafter therefore has the fundamental objective of showing whether instruction in critical thinking (ARDESOS-DIAPROVE) influences students’ metacognitive processes. One consequence of this is that critical thinking improves with the use of metacognition. The sample was comprised of first-year psychology students at Public University of the North of Spain who were undergoing the aforementioned program; PENCRISAL was used to evaluate critical thinking skills and the Metacognitive Activities Inventory (MAI) for evaluating metacognition. We expected an increase in critical thinking scores and metacognition following this intervention. As a conclusion, we indicate actions to incentivize metacognitive work among participants, both individually via reflective questions and decision diagrams, and at the interactional level with dialogues and reflective debates which strengthen critical thinking.

Introduction

One of the principal objectives which education must cover is helping our students become autonomous and effective. Students’ ability to use strategies which help them direct their motivation toward action in the direction of the meta-proposal is a central aspect to keep at the front of our minds when considering education. This is where metacognition comes into play—knowledge about knowledge itself, a component which is in charge of directing, monitoring, regulating, organizing, and planning our skills in a helpful way, once these have come into operation. Metacognition helps form autonomous students, increasing consciousness about their own cognitive processes and their self-regulation so that they can regulate their own learning and transfer it to any area of their lives. As we see, it is a conscious activity of high-level thinking which allows us to look into and reflect upon how we learn and to control our own strategies and learning processes. We must therefore approach a problem which is increasing in our time, that of learning and knowledge from the perspective of active participation by students. To achieve these objectives of “learning to learn” we must use adequate cognitive learning strategies, among which we can highlight those oriented toward self-learning, developing metacognitive strategies, and critical thinking.

Metacognition is one of the research areas, which has contributed the most to the formation of the new conceptions of learning and teaching. In this sense, it has advanced within the constructivist conceptions of learning, which have attributed an increasing role to student consciousness and to the regulation which they exercise over their own learning ( Glaser, 1994 ).

Metacognition was initially introduced by John Flavell in the early 1970s. He affirmed that metacognition, on one side, refers to “the knowledge which one has about his own cognitive processes products, or any other matter related with them” and on the other, “to the active supervision and consequent regulation and organization of these processes in relation with the objects or cognitive data upon which they act” ( Flavell, 1976 ; p. 232). Based on this, we can differentiate two components of metacognition: one of a declarative nature, which is metacognitive knowledge, referring to knowledge of the person and the task, and another of a procedural nature, which is metacognitive control or self-regulated learning, which is always directed toward a goal and controlled by the learner.

Different authors have pointed out that metacognition presents these areas of thought or skills, aimed knowledge or toward the regulation of thought and action, mainly proposing a binary organization in which attentional processes are oriented, on occasions, toward an object or subject, and the other hand, toward to interact with objects and/or subjects ( Drigas and Mitsea, 2021 ). However, it is possible to understand metacognition from another approach that establishes more levels of use of metacognitive thinking to promote knowledge, awareness, and intelligence, known as the eight pillars of metacognition model ( Drigas and Mitsea, 2020 ). These pillars allow thought to promote the use of deep knowledge, cognitive processes, self-regulation, functional adaptation to society, pattern recognition and operations, and even meaningful memorization ( Drigas and Mitsea, 2020 ).

In addition to the above, Drigas and Mitsea’s model establishes different levels where metacognition could be used, in a complex sequence from stimuli to transcendental ideas, in which each of the pillars could manifest a different facet of the process metacognitive, thus establishing a dialectical and integrative approach to learning and knowledge, allowing it to be understood as an evolutionary and complex process in stages ( Drigas and Mitsea, 2021 ).

All this clarifies the importance of and need for metacognition, not only in education but also in our modern society, since this need to “teach how to learn” and the capacity to “learn how to learn” in order to achieve autonomous learning and transfer it to any area of our lives will let us face problems more successfully. This becomes a relevant challenge, especially today where it is required to have a broad view regarding reflection and consciousness, and to transcend simplistic and reductionist models that seek to center the problem of knowledge only around the neurobiological or the phenomenological scope ( Sattin et al., 2021 ).

Critical thinking depends largely on these mechanisms functioning well and being conscious of the processes used, since this gives us the opportunity to understand what has not been done well and correct it in the future. Consciousness for critical thinking would imply a continuous process of reuse of thought, in escalations that allow thinking to be oriented both toward the objects of the world and toward the subjective interior, allowing to determine the ideas that give greater security to the person, and in that perspective, the metacognitive process, represents this use of Awareness, also allowing the generation of an identity of knowing being ( Drigas and Mitsea, 2021 ).

We know that thinking critically involves reasoning and deciding to effectively solve a problem or reach goals. However, effective use of these skills requires a certain degree of consciousness and regulation of them. The ARDESOS-DIAPROVE program seeks precisely to foment critical thinking, in part, via metacognition ( Saiz and Rivas, 2011 , 2012 , 2016 ).

However, it is not only centered on developing cognitive components, as this would be an important limitation. Since the 1990s, it has been known that non-cognitive components play a crucial role in developing critical thinking. However, there are few studies focusing on this relation. This intervention therefore considers both dimensions, where metacognitive processes play an essential role by providing evaluation and control mechanisms over the cognitive dimension.

Metacognition and Critical Thinking

Critical Thinking is a concept without a firm consensus, as there have been and still are varying conceptions regarding it. Its nature is so complex that it is hard to synthesize all its aspects in a single definition. While there are numerous conceptions about critical thinking, it is necessary to be precise about which definition we will use. We understand that “ critical thinking is a knowledge-seeking process via reasoning skills to solve problems and make decisions which allows us to more effectively achieve our desired results” ( Saiz and Rivas, 2008 , p. 131). Thinking effectively is desirable in all areas of individual and collective action. Currently, the background of the present field of critical thinking is also based in argumentation. Reasoning is used as the fundamental basis for all activities labeled as thinking. In a way, thinking cannot easily be decoupled from reasoning, at least if our understanding of it is “deriving something from another thing.” Inference or judgment is what we essentially find behind the concept of thinking. The question, though, is whether it can be affirmed that thinking is only reasoning. Some defend this concept ( Johnson, 2008 ), while others believe the opposite, that solving problems and making decisions are activities which also form part of thinking processes ( Halpern, 2003 ; Halpern and Dunn, 2021 , 2022 ). To move forward in this sense, we will return to our previous definition. In that definition, we have specified intellectual activity with a goal intrinsic to all mental processes, namely, seeking knowledge. Achieving our ends depends not only on the intellectual dimension, as we may need our motor or perceptive activities, so it contributes little to affirm that critical thinking allows us to achieve our objectives as we can also achieve them by doing other activities. It is important for us to make an effort to identify the mental processes responsible for thinking and distinguish them from other things.

Normally, we think to solve our problems. This is the second important activity of thought. A problem can be solved by reasoning, but also by planning course of action or selecting the best strategy for the situation. Apart from reasoning, we must therefore also make decisions to resolve difficulties. Choosing is one of the most frequent and important activities which we do. Because of this, we prefer to give it the leading role it deserves in a definition of thinking. Solving problems demands multiple intellectual activities, including reasoning, deciding, planning, etc. The final characteristic goes beyond the mechanisms peculiar to inference. What can be seen at the moment of delineating what it means to think effectively is that concepts are grouped together which go beyond the nuclear ideas of what has to do with inferring or reasoning. The majority of theoreticians in the field ( APA, 1990 ; Ennis, 1996 ; Halpern, 1998 , 2003 ; Paul and Elder, 2001 ; Facione, 2011 ; Halpern and Dunn, 2021 , 2022 ) consider that, in order to carry out this type of thinking effectively, apart from having this skill set, the intervention of other types of components is necessary, such as metacognition and motivation. This is why we consider it necessary to speak about the components of critical thinking, as we can see in Figure 1 :

Components of critical thinking ( Saiz, 2020 ).

In the nature of thinking, there are two types of components: the cognitive and the non-cognitive. The former include perception, learning, and memory processes. Learning is any knowledge acquisition mechanism, the most important of which is thinking. The latter refer to motivation and interests (attitudes tend to be understood as dispositions, inclinations…something close to motives); with metacognition remaining as a process which shares cognitive and non-cognitive aspects as it incorporates aspects of both judgment (evaluation) and disposition (control/efficiency) about thoughts ( Azevedo, 2020 ; Shekhar and Rahnev, 2021 ). Both the cognitive and non-cognitive components are essential to improve critical thinking, as one component is incomplete without the other, that is, neither cognitive skills nor dispositions on their own suffice to train a person to think critically. In general, relations are bidirectional, although for didactic reasons only unidirectional relations appear in Figure 1 ( Rivas et al., 2017 ). This is because learning is a dynamic process which is subject to all types of influence. For instance, if a student is motivated, they will work more and better—or at least, this is what is hoped for. If they can achieve good test scores as well, it can be supposed that motivation is reinforced, so that they will continue existing behaviors in the same direction that is, working hard and well on their studies. This latter point appears to arise at least because of an adjustment between expectations and reality which the student achieves thanks to metacognition, which allows them to effectively attribute their achievements to their efforts ( Ugartetxea, 2001 ).

Metacognition, which is our interest in this paper, should also have bidirectional relations with critical thinking. Metacognition tends to be understood as the degree of consciousness which we have about our own mental processes and similar to the capacity for self-regulation, that is, planning and organization ( Mayor et al., 1993 ). We observe that these two ideas have very different natures. The former is simpler, being the degree of consciousness which we reach about an internal mechanism or process. The latter is a less precise idea, since everything which has to do with self-regulation is hard to differentiate from a way of understanding motivation, such as the entire tradition of intrinsic motivation and self-determination from Deci, his collaborators, and other authors of this focus (see, e.g., Deci and Ryan, 1985 ; Ryan and Deci, 2000 ). The important thing is to emphasize the executive dimension of metacognition, more than the degree of consciousness, for practical reasons. It can be expected that this dimension has a greater influence on the learning process than that of consciousness, although there is little doubt that we have to establish both as necessary and sufficient conditions. However, the data must speak in this regard. Due to all of this, and as we shall see hereinafter, the intervention designed incorporates both components to improve critical thinking skills.

We can observe, though, that the basic core of critical thinking continues to be topics related to skills, in our case, reasoning, problem-solving, and decision-making. The fact that we incorporate concepts of another nature, such as motivation, in a description of critical thinking is justified because it has been proven that, when speaking about critical thinking, the fact of centering solely on skills does not allow for fully gathering its complexity. The purpose of the schematic in Figure 2 is to provide conceptual clarity to the adjective “critical” in the expression critical thinking . If we understand critical to refer to effective , we should also consider that effectiveness is not, as previously mentioned, solely achieved with skills. They must be joined together with other mechanisms during different moments. Intellectual skills alone cannot achieve the effectiveness assumed within the term “critical.” First, for said skills to get underway, we must want to do so. Motivation therefore comes into play before skills and puts them into operation. For its part, metacognition allows us to take advantage of directing, organizing, and planning our skills and act once they have begun to work. Motivation thus activates our abilities, while metacognition lets them be more effective. The final objective should always be to gain proper knowledge of reality to resolve our problems.

Purpose of critical thinking ( Saiz, 2020 , p.27).

We consider that the fact of referring to components of critical thinking while differentiating the skills of motivation and metacognition aids with the conceptual clarification we seek. On one side, we specify the skills which we discuss, and on another, we mention which other components are related to, and even overlap with them. We must be conscious of how difficult it is to find “pure” mental processes. Planning a course of action, an essential trait of metacognition, demands reflection, prediction, choice, comparison, and evaluation… And this, evidently, is thinking. The different levels or dimensions of our mental activity must be related and integrated. Our aim is to be able to identify what is substantial in thinking to know what we are able to improve and evaluate.

It is widely known that for our personal and professional functioning, thinking is necessary and useful. When we want to change a situation or gain something, all our mental mechanisms go into motion. We perceive the situation, identify relevant aspects of the problem, analyze all the available information, and appraise everything we analyze. We make judgments about the most relevant matters, decide about the options or pathways for resolution, execute the plan, obtain results, evaluate the results, estimate whether we have achieved our purpose and, according to the level of satisfaction following this estimation, consider our course of action good, or not.

The topic we must pose now is what things are teachable. It is useful to specify that what is acquired is clearly cognitive and some of the non-cognitive, because motivation can be stimulated or promoted, but not taught. The concepts of knowledge and wisdom are its basis. Mental representation and knowledge only become wisdom when we can apply it to reality, when we take it out of our mind and adequately situate it in the world. For our teaching purposes, we only have to take a position about whether knowledge is what makes critical thinking develop, or vice versa. For us, skills must be directly taught, and dominion is secondary. Up to now, we have established the components of critical thinking, but these elements still have to be interrelated properly. What we normally find are skills or components placed side by side or overlapping, but not the ways in which they influence each other. Lipman (2003) may have developed the most complete theory of critical and creative thinking, along Paul and his group, in second place, with their universal thought structures ( Paul and Elder, 2006 ). However, a proposal for the relation between the elements is lacking.

To try to explain the relation between the components of thought, we will use Figure 2 as an aid.

The ultimate goal of critical thinking is change that is, passing from one state of wellbeing into a better state. This change is only the fruit of results, which must be the best. Effectiveness is simple achieving our goals in the best way possible. There are many possible results, but for our ends, there are always some which are better than others. Our position must be for effectiveness, the best response, the best solution. Reaching a goal is resolving or achieving something, and for this, we have mechanisms available which tell us which are the best course of action. Making decisions and solving problems are fundamental skills which are mutually interrelated. Decision strategies come before a solution. Choosing a course of action always comes before its execution, so it is easy to understand that decisions contribute to solutions.

Decisions must not come before reflection, although this often can and does happen. As we have already mentioned, the fundamental skills of critical thinking, in most cases, have been reduced to reasoning, and to a certain degree, this is justified. There is an entire important epistemological current behind this, within which the theory of argumentation makes no distinction, at least syntactically, between argumentation and explanation. However, for us this distinction is essential, especially in practice ( Saiz, 2020 ). We will only center on an essential difference for our purpose. Argumentation may have to do with values and realities, but explanation only has to do with the latter. We can argue about beliefs, convictions, and facts, but we can only explain realities. Faced with an explanation of reality, any argumentation would be secondary. Thus, explanation will always be the central skill in critical thinking.

The change which is sought is always expressed in reality. Problems always are manifested and resolved with actions, and these are always a reality. An argument about realities aids in explaining them. An argument about values upholds a belief or a conviction. However, beliefs always influence behavior; thus, indirectly, the argument winds up being about realities. One may argue, for example, only for or against the death penalty, and reach the conviction that it is good or bad and ultimately take a position for or against allowing it. This is why we say that deciding always comes before resolving; furthermore, resolution always means deciding about something in a particular direction—it always means choosing and taking an option; furthermore, deciding is often only from two possibilities, the better or that which is not better, or which is not as good. Decisions are made based on the best option possible of all those which can be presented. Resolution is a dichotomy. Since our basic end lies within reality, explanation must be constituted as the basic pillar to produce change. Argumentation must therefore be at the service of causality (explanation), and both must be in the service of solid decisions leading us to the best solution or change of situation. We now believe that the relation established in Figure 2 can be better understood. From this relation, we propose that thinking critically means reaching the best explanation for an event, phenomenon, or problem in order to know how to effectively resolve it ( Saiz, 2017 , p.19). This idea, to our judgment, is the best summary of the nature of critical thinking. It clarifies details and makes explicit the components of critical thinking.

Classroom Activities to Develop Metacognition

We will present a set of strategies to promote metacognitive work in the classroom in this section, aimed at improving critical thinking skills. These strategies can be applied both at the university level and the secondary school level; we will thus focus on these two levels, although metacognitive strategies can be worked on from an earlier age ( Jaramillo and Osses, 2012 ; Tamayo-Alzate et al., 2019 ) and some authors have indicated that psychological maturity has a greater impact on effectively achieving metacognition ( Sastre-Riba, 2012 ; García et al., 2016 ).

At the individual level, metacognition can be worked on via applying questions aimed at the relevant tasks which must be undertaken regarding a task (meta-knowledge questions), for example:

• Do I know how much I know about this subject?
• Do I have clear instructions and know what action is expected from me?
• How much time do I have?
• Am I covering the proper and necessary subjects, or is there anything important left out?
• How do I know that my work is right?
• Have I covered every point of the rubric for the work to gain a good grade or a sufficient level?

These reflective questions facilitate supervising knowledge level, resource use, and the final product achieved, so that the decisions taken for said activities are the best and excellent learning results are achieved.

Graphs or decision diagrams can also be used to aid in organizing these questions during the different phases of executing a task (planning, progress, and final evaluation), which is clearly linked with the knowledge and control processes of metacognition ( Mateos, 2001 ). These diagrams are more complex and elaborate strategies than the questions, but are effective when monitoring the steps considered in the activity ( Ossa et al., 2016 ). Decision diagrams begin from a question or task, detailing the principal steps to take, and associating an alternative (YES or NO) to each step, which leads to the next step whenever the decision is affirmative, or to improve or go further into the step taken if the decision is negative.

Finally, we can work on thinking aloud, a strategy which facilitates making the thoughts explicit and conscious, allowing us to monitor their knowledge, decisions, and actions to promote conscious planning, supervision and evaluation ( Ávila et al., 2017 ; Dahik et al., 2019 ). For example:

• While asking a question, the student thinks aloud: I am having problems with this part of the task, and I may have to ask the teacher to know whether I am right.

Thinking aloud can be done individually or in pairs, allowing for active monitoring of decisions and questions arising from cognitive and procedural work done by the student.

Apart from the preceding strategies, it is also possible to fortify metacognitive development via personal interactions based on dialogue between both the students themselves and between the teacher and individual students. One initial strategy, similar to thinking out loud in pairs, is reflective dialogue between teacher and student, a technique which allows for exchanging deep questions and answers, where the student becomes conscious of their knowledge and practice thanks to dialogical interventions by the teacher ( Urdaneta, 2014 ).

Reflective dialogue can also be done via reflective feedback implemented by the teacher for the students to learn by themselves about the positive and negative aspects of their performance on a task.

Finally, another activity based on dialogue and interaction is related to metacognitive argumentation ( Sánchez-Castaño et al., 2015 ), a strategy which uses argumentative resources to establish a valid argumentative structure to facilitate responding to a question or applying it to a debate. While argumentative analysis is based on logic and the search for solid reasons, these can have higher or lower confidence and reliability as a function of the data which they provide. Thus, if a reflective argumentative process is performed, via questioning reasons or identifying counterarguments, there is more depth and density in the argumentative structure, achieving greater confidence and validity.

We can note that metacognition development strategies are based on reflective capacity, which allow thought to repeatedly review information and decisions to consider, without immediately taking sides or being carried away by superficial or biased ideas or data. Critical thought benefits strongly from applying this reflective process, which guides both data management and cognitive process use. These strategies can also be developed in various formats (written, graphic, oral, individual, and dialogical), providing teachers a wide range of tools to strengthen learning and thinking.

Metacognitive Strategies to Improve Critical Thinking

In this section, we will describe the fundamental metacognitive strategies addressed in our critical thinking skills development program ARDESOS-DIAPROVE.

First, one of the active learning methodologies applied is Problem-Based Learning (PBL). This pedagogical strategy is student-centered and encourages autonomous and participative learning, orienting students toward more active and decisive learning. In PBL each situation must be approached as a problem-solving task, making it necessary to investigate, understand, interpret, reason, decide, and resolve. It is presented as a methodology which facilitates joint knowledge acquisition and skill learning. It is also good for working on daily problems via relevant situations, considerably reducing the distance between learning context and personal/professional life and aiding the connection between theory and practice, which promote the highly desired transference. It favors organization and the capacity to decide about problem-solving, which also improves performance and knowledge about the students’ own learning processes. Because of all this, this methodology aids in reflection and analysis processes, which in turn promotes metacognitive skill development.

The procedure which we carried out in the classroom with all the activities is based on the philosophy of gradual learning control transference ( Mateos, 2001 ). During instruction, the teacher takes on the role of model and guide for students’ cognitive and metacognitive activity, gradually bringing them into participating in an increasing level of competency, and slowly withdrawing support in order to attain control over the students’ learning process. This methodology develops in four phases: (1) explicit instruction, where the teacher directly explains the skills which will be worked on; (2) guided practice, where the teacher acts as a collaborator to guide and aid students in self-regulation; and (3) cooperative practice, where cooperative group work facilitates interaction with a peer group collaborating to resolve the problem. By explaining, elaborating, and justifying their own points of view and alternative solutions, greater consciousness, reflection, and control over their own cognitive processes is promoted. Finally, (4) individual practice is what allows students to place their learning into practice in individual evaluation tasks.

Regarding the tasks, it is important to highlight that the activities must be aimed not only at acquiring declarative knowledge, but also at procedural knowledge. The objective of practical tasks, apart from developing fundamental knowledge, is to develop CT skills among students in both comprehension and expression in order to favor their learning and its transference. The problems used must be common situations, close to our students’ reality. The important thing in our task of teaching critical thinking is its usefulness to our students, which can only be achieved during application since we only know something when we are capable of applying it. We are not interested in students merely developing critical skills; they must also be able to generalize their intellectual skills, for which they must perceive them as useful in order to want to acquire them. Finally, they will have to actively participate to apply them to solving problems. Furthermore, if we study the different ways of reasoning without context, via overly academic problems, their application to the personal sphere becomes impossible, leading them to be considered hardly useful. This makes it important to contextualize skills within everyday problems or situations which help us get students to use them regularly and understand their usefulness.

Reflecting on how one carries things out in practice and analyzing mistakes are ways to encourage success and autonomy in learning. These self-regulation strategies are the properly metacognitive part of our study. The teacher has various resources to increase these strategies, particularly feedback oriented toward task resolution. Similarly, one of the most effective instruments to achieve it is using rubrics, a central tool for our methodology. These guides, used in student performance evaluations, describe the specific characteristics of a task at various performance levels, in order to clarify expectations for students’ work, evaluate their execution, and facilitate feedback. This type of technique also allows students to direct their own activity. We use them with this double goal in mind; on the one hand, they aid students in carrying out tasks, since they help divide the complex tasks they have to do into simpler jobs, and on the other, they help evaluate the task. Rubrics guide students in the skills and knowledge they need to acquire as well as facilitating self-evaluation, thereby favoring responsibility in their learning. Task rubrics are also the guide for evaluation which teachers carry out in classrooms, where they specify, review, and correctly resolve the tasks which students do according to the rubric criteria. Providing complete feedback to students is a crucial aspect for the learning process. Thus, in all sessions time is dedicated to carrying it out. This is what will allow them to move ahead in self-regulated skill learning.

According to what we have seen, there is a wide range of positions when it comes to defining critical thinking. However, there is consensus in the fact that critical thinking involves cognitive, attitudinal, and metacognitive components, which together favor proper performance in critical thinking ( Ennis, 1987 ; Facione, 1990 ). This important relation between metacognition and critical thinking has been widely studied in the literature ( Berardi-Coletta et al., 1995 ; Antonietti et al., 2000 ; Kuhn and Dean, 2004 ; Black, 2005 ; Coutinho et al., 2005 ; Orion and Kali, 2005 ; Schroyens, 2005 ; Akama, 2006 ; Choy and Cheah, 2009 ; Magno, 2010 ; Arslan, 2014 ) although not always in an applied way. Field studies indicate the existence of relations between teaching metacognitive strategies and progress in students’ higher-order thinking processes ( Schraw, 1998 ; Kramarski et al., 2002 ; Van der Stel and Veenman, 2010 ). Metacognition is thus considered one of the most relevant predictors of achieving a complex higher-order thought process.

Along the same lines, different studies show the importance of developing metacognitive skills among students as it is related not only with developing critical thinking, but also with academic achievement and self-regulated learning ( Klimenko and Alvares, 2009 ; Magno, 2010 ; Doganay and Demir, 2011 ; Özsoy, 2011 ). Klimenko and Alvares (2009) indicated that one way for students to acquire necessary tools to encourage autonomous learning is making cognitive and metacognitive strategies explicit and well-used and that teachers’ role is to be mediators and guides. Inspite of this evidence, there is less research about the use of metacognitive strategies in encouraging critical thinking. The principal reason is probably that it is methodologically difficult to gather direct data about active metacognitive processes which are complex by nature. Self-reporting is also still very common in metacognition evaluation, and there are few studies which have included objective measurements aiding in methodological precision for evaluating metacognition.

However, in recent years, greater importance has been assigned to teaching metacognitive skills in the educational system, as they aid students in developing higher-order thinking processes and improving their academic success ( Flavell, 2004 ; Larkin, 2009 ). Because of this, classrooms have seen teaching and learning strategies emphasizing metacognitive knowledge and regulation. Returning to our objective, which is to improve critical thinking via the ARDESOS-DIAPROVE program, we have achieved our goal in an acceptable way ( Saiz and Rivas, 2011 , 2012 , 2016 ).

However, we need to know which specific factors contribute to this improvement. We have covered significant ground through different studies, one of which we present here. In this one, we attempt to find out the role of metacognition in critical thinking. This is the central objective of the study. Our program includes motivational and metacognitive variables. Therefore, we seek to find out whether metacognition improves after this instruction program focused on metacognition. Therefore, our hypothesis is simple: we expect that the lesson will improve our students’ metacognition. The idea is to know whether applying metacognition helps us achieve improved critical thinking and whether after this change metaknowledge itself improves. In other words, improved critical thinking performance will make us think better about thinking processes themselves. If this can be improved, we can expect that in the future it will have a greater influence on critical thinking. The idea is to be able to demonstrate that applying specifically metacognitive techniques, the processes themselves will subsequently improve in quality and therefore contribute better volume and quality to reasoning tasks, decision-making and problem-solving.

Materials and Methods

Participants.

In the present study, we used a sample of 89 students in a first-year psychology course at Public University of the North of Spain. 82% (73) were women, and the other 18% (16) were men. Participants’ median age was 18.93 ( SD 1.744).

Instruments

Critical thinking test.

To measure critical thinking skills, we applied the PENCRISAL test ( Saiz and Rivas, 2008 ; Rivas and Saiz, 2012 ). The PENCRISAL is a battery consisting of 35 production problem situations with an open-answer format, composed of five factors: Deductive Reasoning , Inductive Reasoning , Practical Reasoning , Decision-Making , and Problem-Solving , with seven items per factor. Items for each factor gather the most representative structures of fundamental critical thinking skills.

The items’ format is open, so that the person has to answer a concrete question, adding a justification for the reasons behind their answer. Because of this, there are standardized correction criteria assigning values between 0 and 2 points as a function of answer quality. This test offers us a total score of critical thinking skills and another five scores referring to the five factors. The value range is located between 0 and 72 points as a maximum limit for total test scoring, and between 0 and 14 for each of the five scales. The reliability measures present adequate precision levels according to the scoring procedures, with the lowest Cronbach’s alpha values at 0.632, and the test–retest correlation at 0.786 ( Rivas and Saiz, 2012 ). PENCRISAL administration was done over the Internet via the evaluation platform SelectSurvey.NET V5: http://24.selectsurvey.net/pensamiento-critico/Login.aspx .

Metacognitive Skill Inventory

Metacognitive skill evaluation was done via the metacognitive awareness inventory from Schraw and Dennison (1994) (MAI; Huertas Bustos et al., 2014 ). This questionnaire has 52 Likert scale-type items with five points. The items are distributed in two general dimensions: cognitive knowledge (C) and regulation of cognition (R). This provides ample coverage for the two aforementioned ideas about metaknowledge. There are also eight defined subcategories within each general dimension. For C, these are: declarative knowledge (DK), procedural knowledge (PK), and conditional knowledge (CK). In R, we find: organization (O), monitoring (M), and evaluation (E). This instrument comprehensively, and fairly clearly, brings together essential aspects of metacognition. On one side, there is the level of consciousness, containing types of knowledge—declarative, procedural, and strategic. On the other, it considers everything important in the processes of self-regulation, planning, organization, direction or control (monitoring), adjustment (troubleshooting), and considering the results achieved (evaluation). It provides a very complete vision of everything important in this dimension. Cronbach’s alpha for this instrument is 0.94, showing good internal consistency.

Intervention Program

As previously mentioned, in this study, we applied the third version of the ARDESOS_DIAPROVE program ( Saiz and Rivas, 2016 ; Saiz, 2020 ), with the objective of improving thinking skills. This program is centered on directly teaching the skills which we consider essential to develop critical thinking and for proper performance in our daily affairs. For this, we must use reasoning and good problem-solving and decision-making strategies, with one of the most fundamental parts of our intervention being the use of everyday situations to develop these abilities.

DIAPROVE methodology incorporates three new and essential aspects: developing observation, the combined use of facts and deduction, and effective management of de-confirmation procedures, or discarding hypotheses. These are the foundation of our teaching, which requires specific teaching–learning techniques.

The intervention took place over 16 weeks and is designed to be applied in classrooms over a timeframe of 55–60 h. The program is applied in classes of around 30–35 students divided into groups of four for classwork in collaborative groups, and organized into six activity blocks: (1) nature of critical thinking, (2) problem-solving and effectiveness, (3) explanation and causality, (4) deduction and explanation, (5) argumentation and deduction, and (6) problem-solving and decision-making. These blocks are assembled maintaining homogeneity, facilitating a global integrated skill focus which helps form comprehension and use of the different structures in any situation as well as a greater degree of ability within the domain of each skill.

Our program made an integrated use of problem-based learning (PBL) and cooperative learning (CL) as didactic teaching and learning strategies in the critical thinking program. These methodologies jointly exert a positive influence on the students, allowing them to participate more actively in the learning process, achieve better results in contextualizing content and developing skills and abilities for problem-solving, and improve motivation.

To carry out our methodology in the classrooms, we have designed a teaching system aligned with these directives. Two types of tasks are done: (1) comprehension and (2) production. The materials we used to carry out these activities are the same for all the program blocks. One key element in our aim of teaching how to think critically must be its usefulness to our students, which is only achieved through application. This makes it important to contextualize reasoning types within common situations or problems, aiding students to use them regularly and understand their usefulness. Our intention with the materials we use is to face the problems of transference, usefulness, integrated skills, and how to produce these things. Accordingly, the materials used for the tasks are: (1) common situations and (2) professional/personal problems.

The tasks which the students perform take place over a week. They work in cooperative groups in class, and then review, correct, and clarify together, promoting reflection on their achievements and errors, which fortifies metacognition. Students get the necessary feedback on the work performed which will help them progressively acquire fundamental procedural contents. Our goal here is that students become conscious of their own thought processes in order to improve them. In this way, via the dialogue achieved between teachers and students as well as between the students themselves in their cooperative work, metacognition is developed. For conscious performance of tasks, the students will receive rubrics for each and every task to guide them in their completion.

Application of the ARDESOS-DIAPROVE program was done across a semester in the Psychology Department of the Public University of the North of Spain. One week before teaching began; critical thinking and metacognition evaluations were done. This was also done 1 week after the intervention ended, in order to gather the second measurement for PENCRISAL and MAI. The timelapse between the pre-treatment and post-treatment measurements was 4 months. The intervention was done by instructors with training and good experience in the program.

To test our objective, we used a quasi-experimental pre-post design with repeated measurements.

Statistical Analysis

For statistical analysis, we used the IBM SPSS Statistics 26 statistical packet. The statistical tools and techniques used were: frequency and percentage tables for qualitative variables, exploratory and descriptive analysis of quantitative variables with a goodness of fit test to the normal Gaussian model, habitual descriptive statistics (median, SD, etc.) for numerical variables, and Student’s t -tests for significance of difference.

To begin, a descriptive analysis of the study variables was carried out. Tables 1 , ​ ,2 2 present the summary of descriptions for the scores obtained by students in the sample, as well as the asymmetry and kurtosis coefficients for their distribution.

As we see in the description of all study variables, the evidence is that the majority of them adequately fit the normal model, although some present significant deviations which can be explained by sample size.

Next, to verify whether there were significant differences in the metacognition variable based on measurements before and after the intervention, we contrasted medians for samples related with Student’s t -test (see Table 3 ).

Comparison of the METAKNOWLEDGE variable as a function of PRE-POST measurements.

The results show that there are significant differences in the metaknowledge scale total and in most of its dimensions, where all the post medians for both the scale overall and for the three dimensions of the knowledge factor (declarative, procedural, and conditional) are higher than the pre-medians. However, in the cognition regulation dimension, there are only significant differences in the total and in the planning, organization, and monitoring dimensions. The medians are also greater in the post-test than the pre-test. However, the troubleshooting and evaluation dimensions do not differ significantly after intervention.

Finally, for critical thinking skills, the results show significant differences in the scale total and in the five factors regarding the measurement time, where performance medians rise after intervention (see Table 4 ).

Comparison of the CRITICAL THINKING variable as a function of PRE-POST measurements.

These results show how metacognition improves due to CT intervention, as well as how critical thinking also improves with metacognitive intervention and CT skills intervention. Thus, it improves how people think about thinking as well as about the results achieved, since metacognition supports decision-making and final evaluation about proper strategies to solve problems.

Discussion and Conclusions

The general aim of our study was to know whether a critical thinking intervention program can also influence metacognitive processes. We know that our teaching methodology improves cross-sectional skills in argumentation, explanation, decision-making, and problem-solving, but we do not know if this intervention also directly or indirectly influences metacognition. In our study, we sought to shed light on this little-known point. If we bear in mind the centrality of how we think about thinking for our cognitive machinery to function properly and reach the best results possible in the problems we face, it is hard to understand the lack of attention given to this theme in other research. Our study aimed to remedy this deficiency somewhat.

As said in the introduction, metacognition has to do with consciousness, planning, and regulation of our activities. These mechanisms, as understood by many authors, have a blended cognitive and non-cognitive nature, which is a conceptual imprecision; what is known, though, is the enormous influence they exert on fundamental thinking processes. However, there is a large knowledge gap about the factors which make metacognition itself improve. This second research lacuna is what we have partly aimed to shrink here as well with this study. Our guide has been the idea of knowing how to improve metacognition from a teaching initiative and from the improvement of fundamental critical thinking skills.

Our study has shed light in both directions, albeit in a modest way, since its design does not allow us to unequivocally discern some of the results obtained. However, we believe that the data provide relevant information to know more about existing relations between skills and metacognition, something which has seen little contrast. These results allow us to better describe these relations, guiding the design of future studies which can better discern their roles. Our data have shown that this relation is bidirectional, so that metacognition improves thinking skills and vice versa. It remains to establish a sequence of independent factors to avoid this confusion, something which the present study has aided with to be able to design future research in this area.

As the results show, total differences in almost all metaknowledge dimensions are higher after intervention; specifically, we see how in the knowledge factor the declarative, procedural, and conditional dimensions improve in post-measurements. This improvement moves in the direction we predicted. However, the cognitive regulation dimension only shows differences in the total, and in the planning, organization, and regulation dimensions. We can see how the declarative knowledge dimensions are more sensitive than the procedural ones to change, and within the latter, the dimensions over which we have more control are also more sensitive. With troubleshooting and evaluation, no changes are seen after intervention. We may interpret this lack of effects as being due to how everything referring to evaluating results is highly determined by calibration capacity, which is influenced by personality factors not considered in our study. Regarding critical thinking, we found differences in all its dimensions, with higher scores following intervention. We can tentatively state that this improved performance can be influenced not only by interventions, but also by the metacognitive improvement observed, although our study was incapable of separating these two factors, and merely established their relation.

As we know, when people think about thinking they can always increase their critical thinking performance. Being conscious of the mechanisms used in problem-solving and decision-making always contributes to improving their execution. However, we need to go into other topics to identify the specific determinants of these effects. Does performance improve because skills are metacognitively benefited? If so, how? Is it only the levels of consciousness which aid in regulating and planning execution, or do other factors also have to participate? What level of thinking skills can be beneficial for metacognition? At what skill level does this metacognitive change happen? And finally, we know that teaching is always metacognitive to the extent that it helps us know how to proceed with sufficient clarity, but does performance level modify consciousness or regulation level of our action? Do bad results paralyze metacognitive activity while good ones stimulate it? Ultimately, all of these open questions are the future implications which our current study has suggested. We believe them to be exciting and necessary challenges, which must be faced sooner rather than later. Finally, we cannot forget the implications derived from specific metacognitive instruction, as presented at the start of this study. An intervention of this type should also help us partially answer the aforementioned questions, as we cannot obviate what can be modified or changed by direct metacognition instruction.

Critical Thinking and Academic Research

Academic research focuses on the creation of new ideas, perspectives, and arguments. The researcher seeks relevant information in articles, books, and other sources, then develops an informed point of view within this ongoing "conversation" among researchers.

The research process is not simply collecting data, evidence, or "facts," then piecing together this preexisting information into a paper. Instead, the research process is about inquiry—asking questions and developing answers through serious critical thinking and thoughtful reflection.

As a result, the research process is recursive, meaning that the researcher regularly revisits ideas, seeks new information when necessary, and reconsiders and refines the research question, topic, or approach. In other words, research almost always involves constant reflection and revision.

This guide is designed to help you think through various aspects of the research process. The steps are not sequential, nor are they prescriptive about what steps you should take at particular points in the research process. Instead, the guide should help you consider the larger, interrelated elements of thinking involved in research.

Research Anxiety?

Research is not often easy or straightforward, so it's completely normal to feel anxious, frustrated, or confused. In fact, if you feel anxious, it can be a good sign that you're engaging in the type of critical thinking necessary to research and write a high-quality paper.

Think of the research process not as one giant, impossibly complicated task, but as a series of smaller, interconnected steps. These steps can be messy, and there is not one correct sequence of steps that will work for every researcher. However, thinking about research in small steps can help you be more productive and alleviate anxiety.

Paul-Elder Framework

This guide is based on the "Elements of Reasoning" from the Paul-Elder framework for critical thinking. For more information about the Paul-Elder framework, click the link below.

11.5 Critical Thinking and Research Applications

Learning objectives.

• Analyze source materials to determine how they support or refute the working thesis.
• Identify connections between source materials and eliminate redundant or irrelevant source materials.
• Identify instances when it is appropriate to use human sources, such as interviews or eyewitness testimony.
• Select information from sources to begin answering the research questions.
• Determine an appropriate organizational structure for the research paper that uses critical analysis to connect the writer’s ideas and information taken from sources.

At this point in your project, you are preparing to move from the research phase to the writing phase. You have gathered much of the information you will use, and soon you will be ready to begin writing your draft. This section helps you transition smoothly from one phase to the next.

Beginning writers sometimes attempt to transform a pile of note cards into a formal research paper without any intermediary step. This approach presents problems. The writer’s original question and thesis may be buried in a flood of disconnected details taken from research sources. The first draft may present redundant or contradictory information. Worst of all, the writer’s ideas and voice may be lost.

An effective research paper focuses on the writer’s ideas—from the question that sparked the research process to how the writer answers that question based on the research findings. Before beginning a draft, or even an outline, good writers pause and reflect. They ask themselves questions such as the following:

• How has my thinking changed based on my research? What have I learned?
• Was my working thesis on target? Do I need to rework my thesis based on what I have learned?
• How does the information in my sources mesh with my research questions and help me answer those questions? Have any additional important questions or subtopics come up that I will need to address in my paper?
• How do my sources complement each other? What ideas or facts recur in multiple sources?
• Where do my sources disagree with each other, and why?

In this section, you will reflect on your research and review the information you have gathered. You will determine what you now think about your topic. You will synthesize , or put together, different pieces of information that help you answer your research questions. Finally, you will determine the organizational structure that works best for your paper and begin planning your outline.

Review the research questions and working thesis you developed in Chapter 11 “Writing from Research: What Will I Learn?” , Section 11.2 “Steps in Developing a Research Proposal” . Set a timer for ten minutes and write about your topic, using your questions and thesis to guide your writing. Complete this exercise without looking over your notes or sources. Base your writing on the overall impressions and concepts you have absorbed while conducting research. If additional, related questions come to mind, jot them down.

Selecting Useful Information

At this point in the research process, you have gathered information from a wide variety of sources. Now it is time to think about how you will use this information as a writer.

When you conduct research, you keep an open mind and seek out many promising sources. You take notes on any information that looks like it might help you answer your research questions. Often, new ideas and terms come up in your reading, and these, too, find their way into your notes. You may record facts or quotations that catch your attention even if they did not seem immediately relevant to your research question. By now, you have probably amassed an impressively detailed collection of notes.

You will not use all of your notes in your paper.

Good researchers are thorough. They look at multiple perspectives, facts, and ideas related to their topic, and they gather a great deal of information. Effective writers, however, are selective. They determine which information is most relevant and appropriate for their purpose. They include details that develop or explain their ideas—and they leave out details that do not. The writer, not the pile of notes, is the controlling force. The writer shapes the content of the research paper.

While working through Chapter 11 “Writing from Research: What Will I Learn?” , Section 11.4 “Strategies for Gathering Reliable Information” , you used strategies to filter out unreliable or irrelevant sources and details. Now you will apply your critical-thinking skills to the information you recorded—analyzing how it is relevant, determining how it meshes with your ideas, and finding how it forms connections and patterns.

Writing at Work

When you create workplace documents based on research, selectivity remains important. A project team may spend months conducting market surveys to prepare for rolling out a new product, but few managers have time to read the research in its entirety. Most employees want the research distilled into a few well-supported points. Focused, concise writing is highly valued in the workplace.

Identify Information That Supports Your Thesis

In Note 11.81 “Exercise 1” , you revisited your research questions and working thesis. The process of writing informally helped you see how you might begin to pull together what you have learned from your research. Do not feel anxious, however, if you still have trouble seeing the big picture. Systematically looking through your notes will help you.

Begin by identifying the notes that clearly support your thesis. Mark or group these, either physically or using the cut-and-paste function in your word-processing program. As you identify the crucial details that support your thesis, make sure you analyze them critically. Ask the following questions to focus your thinking:

• Is this detail from a reliable, high-quality source? Is it appropriate for me to cite this source in an academic paper? The bulk of the support for your thesis should come from reliable, reputable sources. If most of the details that support your thesis are from less-reliable sources, you may need to do additional research or modify your thesis.
• Is the link between this information and my thesis obvious—or will I need to explain it to my readers? Remember, you have spent more time thinking and reading about this topic than your audience. Some connections might be obvious to both you and your readers. More often, however, you will need to provide the analysis or explanation that shows how the information supports your thesis. As you read through your notes, jot down ideas you have for making those connections clear.
• What personal biases or experiences might affect the way I interpret this information? No researcher is 100 percent objective. We all have personal opinions and experiences that influence our reactions to what we read and learn. Good researchers are aware of this human tendency. They keep an open mind when they read opinions or facts that contradict their beliefs.

It can be tempting to ignore information that does not support your thesis or that contradicts it outright. However, such information is important. At the very least, it gives you a sense of what has been written about the issue. More importantly, it can help you question and refine your own thinking so that writing your research paper is a true learning process.

Find Connections between Your Sources

As you find connections between your ideas and information in your sources, also look for information that connects your sources. Do most sources seem to agree on a particular idea? Are some facts mentioned repeatedly in many different sources? What key terms or major concepts come up in most of your sources regardless of whether the sources agree on the finer points? Identifying these connections will help you identify important ideas to discuss in your paper.

Look for subtler ways your sources complement one another, too. Does one author refer to another’s book or article? How do sources that are more recent build upon the ideas developed in earlier sources?

Be aware of any redundancies in your sources. If you have amassed solid support from a reputable source, such as a scholarly journal, there is no need to cite the same facts from an online encyclopedia article that is many steps removed from any primary research. If a given source adds nothing new to your discussion and you can cite a stronger source for the same information, use the stronger source.

Determine how you will address any contradictions found among different sources. For instance, if one source cites a startling fact that you cannot confirm anywhere else, it is safe to dismiss the information as unreliable. However, if you find significant disagreements among reliable sources, you will need to review them and evaluate each source. Which source presents a sounder argument or more solid evidence? It is up to you to determine which source is the most credible and why.

Finally, do not ignore any information simply because it does not support your thesis. Carefully consider how that information fits into the big picture of your research. You may decide that the source is unreliable or the information is not relevant, or you may decide that it is an important point you need to bring up. What matters is that you give it careful consideration.

As Jorge reviewed his research, he realized that some of the information was not especially useful for his purpose. His notes included several statements about the relationship between soft drinks that are high in sugar and childhood obesity—a subtopic that was too far outside of the main focus of the paper. Jorge decided to cut this material.

Reevaluate Your Working Thesis

A careful analysis of your notes will help you reevaluate your working thesis and determine whether you need to revise it. Remember that your working thesis was the starting point—not necessarily the end point—of your research. You should revise your working thesis if your ideas changed based on what you read. Even if your sources generally confirmed your preliminary thinking on the topic, it is still a good idea to tweak the wording of your thesis to incorporate the specific details you learned from research.

Jorge realized that his working thesis oversimplified the issues. He still believed that the media was exaggerating the benefits of low-carb diets. However, his research led him to conclude that these diets did have some advantages. Read Jorge’s revised thesis.

Although following a low-carbohydrate diet can benefit some people, these diets are not necessarily the best option for everyone who wants to lose weight or improve their health.

Synthesizing and Organizing Information

By now your thinking on your topic is taking shape. You have a sense of what major ideas to address in your paper, what points you can easily support, and what questions or subtopics might need a little more thought. In short, you have begun the process of synthesizing information—that is, of putting the pieces together into a coherent whole.

It is normal to find this part of the process a little difficult. Some questions or concepts may still be unclear to you. You may not yet know how you will tie all of your research together. Synthesizing information is a complex, demanding mental task, and even experienced researchers struggle with it at times. A little uncertainty is often a good sign! It means you are challenging yourself to work thoughtfully with your topic instead of simply restating the same information.

Use Your Research Questions to Synthesize Information

You have already considered how your notes fit with your working thesis. Now, take your synthesis a step further. Analyze how your notes relate to your major research question and the subquestions you identified in Chapter 11 “Writing from Research: What Will I Learn?” , Section 11.2 “Steps in Developing a Research Proposal” . Organize your notes with headings that correspond to those questions. As you proceed, you might identify some important subtopics that were not part of your original plan, or you might decide that some questions are not relevant to your paper.

Categorize information carefully and continue to think critically about the material. Ask yourself whether the sources are reliable and whether the connections between ideas are clear.

Remember, your ideas and conclusions will shape the paper. They are the glue that holds the rest of the content together. As you work, begin jotting down the big ideas you will use to connect the dots for your reader. (If you are not sure where to begin, try answering your major research question and subquestions. Add and answer new questions as appropriate.) You might record these big ideas on sticky notes or type and highlight them within an electronic document.

Jorge looked back on the list of research questions that he had written down earlier. He changed a few to match his new thesis, and he began a rough outline for his paper.

Review your research questions and working thesis again. This time, keep them nearby as you review your research notes.

• Identify information that supports your working thesis.
• Identify details that call your thesis into question. Determine whether you need to modify your thesis.
• Use your research questions to identify key ideas in your paper. Begin categorizing your notes according to which topics are addressed. (You may find yourself adding important topics or deleting unimportant ones as you proceed.)
• Write out your revised thesis and at least two or three big ideas.

You may be wondering how your ideas are supposed to shape the paper, especially since you are writing a research paper based on your research. Integrating your ideas and your information from research is a complex process, and sometimes it can be difficult to separate the two.

Some paragraphs in your paper will consist mostly of details from your research. That is fine, as long as you explain what those details mean or how they are linked. You should also include sentences and transitions that show the relationship between different facts from your research by grouping related ideas or pointing out connections or contrasts. The result is that you are not simply presenting information; you are synthesizing, analyzing, and interpreting it.

Plan How to Organize Your Paper

The final step to complete before beginning your draft is to choose an organizational structure. For some assignments, this may be determined by the instructor’s requirements. For instance, if you are asked to explore the impact of a new communications device, a cause-and-effect structure is obviously appropriate. In other cases, you will need to determine the structure based on what suits your topic and purpose. For more information about the structures used in writing, see Chapter 10 “Rhetorical Modes” .

The purpose of Jorge’s paper was primarily to persuade. With that in mind, he planned the following outline.

Review the organizational structures discussed in this section and Chapter 10 “Rhetorical Modes” . Working with the notes you organized earlier, follow these steps to begin planning how to organize your paper.

• Create an outline that includes your thesis, major subtopics, and supporting points.
• The major headings in your outline will become sections or paragraphs in your paper. Remember that your ideas should form the backbone of the paper. For each major section of your outline, write out a topic sentence stating the main point you will make in that section.
• As you complete step 2, you may find that some points are too complex to explain in a sentence. Consider whether any major sections of your outline need to be broken up and jot down additional topic sentences as needed.
• Review your notes and determine how the different pieces of information fit into your outline as supporting points.

Collaboration

Please share the outline you created with a classmate. Examine your classmate’s outline and see if any questions come to mind or if you see any area that would benefit from an additional point or clarification. Return the outlines to each other and compare observations.

The structures described in this section and Chapter 10 “Rhetorical Modes” can also help you organize information in different types of workplace documents. For instance, medical incident reports and police reports follow a chronological structure. If the company must choose between two vendors to provide a service, you might write an e-mail to your supervisor comparing and contrasting the choices. Understanding when and how to use each organizational structure can help you write workplace documents efficiently and effectively.

Key Takeaways

• An effective research paper focuses on presenting the writer’s ideas using information from research as support.
• Effective writers spend time reviewing, synthesizing, and organizing their research notes before they begin drafting a research paper.
• It is important for writers to revisit their research questions and working thesis as they transition from the research phase to the writing phrase of a project. Usually, the working thesis will need at least minor adjustments.
• To organize a research paper, writers choose a structure that is appropriate for the topic and purpose. Longer papers may make use of more than one structure.
