Thinking Critically and Analytically about Critical-Analytic Thinking: an Introduction

Situating Higher-Order, Critical, and Critical-Analytic Thinking in Problem- and Project-Based Learning Environments: A Systematic Review

Critical thinking (CT) is widely regarded as an important competence to obtain in education. Students’ exposure to problems and collaboration have been proven helpful in promoting CT processes. These elements are present in student-centered instructional environments such as problem-based and project-based learning (P(j)BL). Next to CT, also higher-order thinking (HOT) and critical-analytic thinking (CAT) contain elements that are present in and fostered by P(j)BL. However, HOT, CT, and CAT definitions are often ill-defined and overlap. The present systematic review, therefore, investigated how HOT, CT, and CAT were conceptualized in P(j)BL environments. Another aim of this study was to review the evidence on the effectiveness of P(j)BL environments in fostering HOT, CT, or CAT. Results demonstrated an absence of CAT in P(j)BL research and a stronger focus on CT processes than CT dispositions (i.e., trait-like tendency or willingness to engage in CT). Further, while we found positive effects of P(j)BL on HOT and CT, there was a lack of clarity and consistency in how researchers conceptualized and measured these forms of thinking. Also, essential components of P(j)BL were often overlooked. Finally, we identified various design issues in effect studies, such as the lack of control groups, that bring the reported outcomes of those investigations into question.

Synthesizing Results From Empirical Research on Computer-Based Scaffolding in STEM Education: A Meta-Analysis

Computer-based scaffolding assists students as they generate solutions to complex problems, goals, or tasks, helping increase and integrate their higher order skills in the process. However, despite decades of research on scaffolding in STEM (science, technology, engineering, and mathematics) education, no existing comprehensive meta-analysis has synthesized the results of these studies. This review addresses that need by synthesizing the results of 144 experimental studies (333 outcomes) on the effects of computer-based scaffolding designed to assist the full range of STEM learners (primary through adult education) as they navigated ill-structured, problem-centered curricula. Results of our random effect meta-analysis (a) indicate that computer-based scaffolding showed a consistently positive (ḡ = 0.46) effect on cognitive outcomes across various contexts of use, scaffolding characteristics, and levels of assessment and (b) shed light on many scaffolding debates, including the roles of customization (i.e., fading and adding) and context-specific support. Specifically, scaffolding's influence on cognitive outcomes did not vary on the basis of context-specificity, presence or absence of scaffolding change, and logic by which scaffolding change is implemented. Scaffolding's influence was greatest when measured at the principles level and among adult learners. Still scaffolding's effect was substantial and significantly greater than zero across all age groups and assessment levels. These results suggest that scaffolding is a highly effective intervention across levels of different characteristics and can largely be designed in many different ways while still being highly effective.
