Vocabulary learning is one of the crucial matters in second language learning. There is a vast body of research in this field which has been done by famous researchers around the world, but still there is no specific solution for extending lexical knowledge in the best way. Therefore, we have conducted a meta-analysis on a body of 30 research…

This article reports the results of a meta-analysis of the effectiveness of 7E learning cycle in science teaching. Totally 35 different effect sizes from 24 experimental studies, comprising 2918 students were included in the meta-analysis. The results confirmed that 7E learning cycle have a positive effect on students' achievement. The overall…

This research synthesis explores how academic achievement relates to two main components of self-regulated learning for students in elementary and secondary school. Two meta-analyses integrated previous findings on (1) the defining metacognitive processes of self-regulated learning and (2) students' use of cognitive strategies. Overall…

This paper serves two purposes. First, it statistically compares learning outcomes of face-to-face, online and blended learning instruction. Then it looks at the instructional practices that are associated with effective blended and online learning. A meta-analysis of 30 studies, with 3,687 participants, resulted in 36 effect sizes. The contrasts…

This study challenges the assertion that an increase in L1 glossing results in more L2 reading comprehension. The results of this study, a quantitative meta-analysis, indicate that there is a significant difference (p = 0.04) in L2 reading comprehension between groups based on how much L1 glossing is provided. It was found that the group with the…

Two previous reviews have indicated that self-regulated strategy instruction (SRSD) is an evidence-based practice that can improve the writing skills of students with emotional and behavioral disorders. The purpose of this meta-analysis is to extend the findings and analytic methods of previous reviews by examining published studies regarding…

This paper explores the concept of pragmatic meta-analytic studies in eLearning. Much educational technology literature focuses on developers and teachers describing and reflecting on their experiences. Few connections are made between these experiential "stories". The data set is fragmented and offers few generalisable lessons. The…

This project consisted of a meta-analysis of U.S. research published from 1980 to 2004 on the effect of specific science teaching strategies on student achievement. The six phases of the project included study acquisition, study coding, determination of intercoder objectivity, establishing criteria for inclusion of studies, computation of effect…
