Problem based learning (PBL) has great potential to enhance learning outcomes and this potential has been investigated and proved in different disciplines by many meta-analysis studies. However, there are not any meta-analysis studies aiming to investigate the effectiveness of problem based learning in English as a Foreign Language (EFL)…

This meta-analysis study aimed to scrutinize the effect of the problem-based learning (PBL) approach on students' academic achievement in science lessons compared to the traditional instructional approach. As research data, the researcher accessed 55 experimental studies as a result of steps of a systematic review with the keywords…

The objective of this study is to perform a meta-analysis of published data on the effects of active learning on Asian students' performance in science, technology, engineering, and mathematics (STEM) subjects. This comprehensive meta-analysis study includes a systematic review of papers related to various active learning approaches and…

Computer-based scaffolding (CBS) has been regarded as an effective way to help individual students complete and gain skill at completing complex tasks beyond their current ability level. Previous meta-analyses also have demonstrated that CBS for collaborative learning leads to positive cognitive outcomes in problem-centered instruction for STEM…

In the past 50 years, the original McMaster PBL model has been implemented, experimented, revised, and modified, and is still evolving. Yet, the development of PBL is not a series of success stories, but rather a journey of experiments, failures and lessons learned. In this paper, we analyzed the meta-analyses and systematic reviews on PBL from…

There has been extensive research using centrality measures in educational settings. One of the most common lines of such research has tested network centrality measures as indicators of success. The increasing interest in centrality measures has been kindled by the proliferation of learning analytics. Previous works have been dominated by…

Preparing students for the real challenges in life is one of the most important goals in education. Constructivism is an approach that uses real-life experiences to construct knowledge. Problem-Based Learning (PBL), for almost five decades now, has been the most innovative constructivist pedagogy used worldwide. However, with the rising…

The aim of this study is to investigate the research trends in dissertations on PBL from 2002 to 2015 in Turkey. For this purpose, the master's and doctorate dissertations in the National Thesis Database of Council of Higher Education (CoHE) were selected for rigorous content analysis. The analysis was utilized to classify the type of study, the…

This meta-analytic study compared the effect of peer-led learning versus non peer-led learning on students' cognitive achievement in post-secondary education. Twenty-eight studies published in English from six countries between 1993 and 2017 were identified and used in the analysis. Result of the analysis on the random-effect model showed a…

Computer-based scaffolding plays a pivotal role in improving students' higher-order skills in the context of problem-based learning for Science, Technology, Engineering and Mathematics (STEM) education. The effectiveness of computer-based scaffolding has been demonstrated through traditional meta-analyses. However, traditional meta-analyses suffer…

This study reports the results of a meta-analysis synthesizing the available literature on the effectiveness of various forms of small-group learning methods on the academic achievement of college students in undergraduate engineering and technology classrooms. The meta-analytic results showed that cooperative learning, collaborative learning,…

To date, researchers have frequently investigated students' attitudes toward courses supported by problem-based learning. There are several studies with different results in the literature. It is necessary to combine and interpret the findings of these studies through a meta-analysis method. This method aims to combine different results of similar…

Computer-based scaffolding provides temporary support that enables students to participate in and become more proficient at complex skills like problem solving, argumentation, and evaluation. While meta-analyses have addressed between-subject differences on cognitive outcomes resulting from scaffolding, none has addressed within-subject gains.…

This research aimed to examine the effect of a problem-based learning approach in comparison to traditional learning approaches. In this context, the question "What is the effect size of problem-based learning on students' attitudes?" was tried to be answered. Among 190 studies made in national and international field between the…

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…
