Given the information age, an important educational objective is cultivating innovators who can propose unique ideas. Learner-centred education is a way to achieve this objective; however, what is the current effectiveness of learner-centred education? A meta-analysis was conducted to analyse 72 effect sizes from 42 quantitative studies to…

In this pre-registered meta-analysis, we investigated the effectiveness of morphology instruction on literacy outcomes for primary school children in English-speaking countries. We were interested in overall reading and spelling outcomes, but we also looked separately at results for trained and untrained words in order to determine whether there…

This meta-analysis synthesizes research on media use in early childhood (0-6 years), word-learning, and vocabulary size. Multi-level analyses included 266 effect sizes from 63 studies (N[subscript total] = 11,413) published between 1988-2022. Among samples with information about race/ethnicity (51%) and sex/gender (73%), most were majority…

The integration of wearables in education environments to enhance teaching and learning is an emerging area of research. However, many studies lack the rigor of formal research designs and results are inconclusive. The purpose of this meta-analysis was to examine the overall effect of wearable use on learning and motivation outcomes and describe…

In a systematic review, 194 studies on learning from animation were analysed. The analysis covers the learning domains, the representational characteristics of the animations, the assessed perceptual and cognitive achievements, and the assessment formats. Research on learning from animation focuses on assessing conceptual at the neglect of…

This methodological guidance article discusses the elements of a high-quality meta-analysis that is conducted within the context of a systematic review. Meta-analysis, a set of statistical techniques for synthesizing the results of multiple studies, is used when the guiding research question focuses on a quantitative summary of study results. In…

This study aims to reinterpret the findings of the studies investigating the effectiveness of using infographics on academic achievement. A mixed methods research design including both quantitative and qualitative sections was adopted on the use of infographics in education. For this purpose, a meta-analysis of 12 empirical studies on the effect…

The aim of this research is to analyze the effect of the flipped learning model on the academic success of students. In this research featuring a descriptive survey model, a quantitative research method has been used. While criterion sampling method has been used for selecting the sample of this research, meta-analysis has been used to analyze the…

This meta-analysis synthesized 26 published single-case design (SCD) studies on Tier 2 behavior interventions implemented within the educational framework of school-wide positive behavioral interventions and supports. We used Tau-U indices to determine the overall magnitudes of effect of the Tier 2 behavior interventions and the potential…

School climate is one of the variables that affect academic achievement, but the level of correlation between school climate and academic achievement differs. On the basis of these inconsistent results between school climate and academic achievement, researchers can use meta-analyses to shed light on relevant literature. The present study ran a…

Family involvement is a cornerstone of early intervention (EI). Therefore, positive caregiver outcomes are vital, particularly in caregiver-implemented interventions. As such, caregiver instructional approaches should optimize adult learning. This study investigated the comparative efficacy of coaching and traditional caregiver instruction on…

The What Works Clearinghouse (WWC) seeks to provide practitioners information about "what works in education." One challenge in understanding "what works" is that effect sizes may not be comparable across studies, which limits the ability to compare the relative effectiveness of multiple interventions. One factor that…

This study introduces an innovative meta-analytic approach, two-stage multilevel meta-analysis that considers the hierarchical structure of single-case experimental design (SCED) data. This approach is unique as it is suitable to include moderators at the intervention level, participant level, and study level, and is therefore especially…

The effect sizes of studies included in a meta-analysis do often not share a common true effect size due to differences in for instance the design of the studies. Estimates of this so-called between-study variance are usually imprecise. Hence, reporting a confidence interval together with a point estimate of the amount of between-study variance…

School leaders today are making important decisions regarding education innovations based on published average effect sizes, even though few understand exactly how effect sizes are calculated or what they mean. This article explains how average effect sizes are determined in meta-analyses and the importance of including measures of variability…
