This article systematically reviews the pedagogical approaches adopted in high school chemistry education with the aim of highlighting the most effective evidence-based instructional practices reported in the literature. For this, a meta-analysis of 35 pedagogical approaches is analyzed, and their effect sizes (Cohen's d) are compared in terms of…

Almost fifty years ago, Barrows (1986) claimed that problem-based learning (PBL) was broad enough that a single methodological description was not possible. It has only grown more complex since. In addition to meaningful variations of PBL, there are several related problem-centered pedagogies, such as case-based learning, project-based learning,…

In this meta-analysis, we examined the effects on students' motivation of student-centered, problem-driven learning methods compared to teacher-centered/lecture-based learning. Specifically, we considered problem-based (PBL), project-based (PjBL), and case-based learning (CBL). We viewed motivation as a multifaceted construct consisting of…

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…

This multiple paper dissertation addressed several issues revolving around the estimation of effect sizes for computer-based scaffolding in problem-centered STEM education. STEM jobs are outpacing all other jobs and STEM workers are expected to solve complex problems. However, students often struggle with complex problem activities. Research on…

An analysis of critical thinking research during 2010 to 2021 was conducted using effect size criteria; subsequently, a model was proposed for teaching and learning management that promoted critical thinking by students at the basic education level using the Thai digital collection data base. Based on a search of past research quality examination…

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…

Project based learning instructional strategies have been used in the K-12 and college setting to activate learning and engagement. Problem Based Learning allows students to learn by taking on real world problems. Research and literature shows that Project Based Learning can increase collaboration, problem-solving skills, communication,…

More than 85% of federally funded research initiatives fail to produce significant positive results (Coalition for Evidence-Based Policy, 2013). Moreover, of the less than 15% that do yield positive results, none show replicability outside of their original setting (Pogrow, 2017; Kizilcec et al., 2020). Mixed results are present in even the most…

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…

Predictors of student academic success do not always replicate well across different learning designs, subject areas, or educational institutions. This suggests that characteristics of a particular discipline and learning design have to be carefully considered when creating predictive models in order to scale up learning analytics. This study…

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…

Best instructional methods are essential tools to bring desirable changes in pre-service science teachers. The available literature lacks enough meta-analytic review illustrating the effect of various instructional methods on pre-service science teachers' learning outcomes. This meta-analytic review identified instructional methods used for…

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…
