Multimedia is ubiquitous in 21st-century education. Cognitive load theory and the cognitive theory of multimedia learning both postulate that the quality of multimedia design heavily influences learning. We sought to identify how to best design multimedia and review how well those learning theories held up to meta-analyses. We conducted an…

A compelling demonstration of implicit learning is the human ability to unconsciously detect and internalize statistical patterns of complex environmental input. This ability, called statistical learning, has been investigated in people with dyslexia using various tasks in different orthographies. However, conclusions regarding impaired or intact…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

When previous research is cited incorrectly, misinformation can infiltrate scientific discourse and undermine scholarly knowledge. One of the more damaging citation issues involves incorrectly citing article content (called quotation errors); therefore, investigating quotation accuracy is an important research endeavor. One field where quotation…

According to the internal/external frame of reference model, academic achievement has a strong impact on people's self-concept, both within and between subjects. We conducted a series of meta-analyses of k = 505 data sets containing the six bivariate correlations between achievement and self-concept in two subjects. Negative paths from achievement…

In this article, we reviewed and interpreted the evidence from 223 rigorous impact evaluations of educational initiatives conducted in 56 low- and middle-income countries. We considered for inclusion in our review all studies in recent syntheses that have reached seemingly conflicting conclusions about which interventions improve educational…

The history of research on interventions for struggling readers in Grades 4 through 12 dates back to 19th-century case studies of seemingly intelligent children who were unable to learn to read. Physicians, psychologists, educators, and others were determined to help them. In the process, they launched a century of research on a wide variety of…

The current review addresses the validity of published meta-analyses in education that determines the credibility and generalizability of study findings using a total of 56 meta-analyses published in education in the 2000s. Our objectives were to evaluate the current meta-analytic practices in education, identify methodological strengths and…

This article systematically reviews the cost study literature as it relates to the treatment of English language learners (ELLs). Despite the substantial number of costing out studies that have been conducted over the past several decades, the school finance literature has failed to focus on ELLs--the fastest growing segment of the school-age…

This article reports a synthesis of intervention studies conducted between 1994 and 2004 with older students (Grades 6-12) with reading difficulties. Interventions addressing decoding, fluency, vocabulary, and comprehension were included if they measured the effects on reading comprehension. Twenty-nine studies were located and synthesized.…

The dominant literature on research synthesis methods has positivist and neo-positivist origins. In recent years, the landscape of research synthesis methods has changed rapidly to become inclusive. This article highlights methodologically inclusive advancements in research synthesis methods. Attention is drawn to insights from interpretive,…

A meta-analysis including 96 experimental studies considers the effects of reinforcement/reward on intrinsic motivation. Results indicate that reward does not decrease intrinsic motivation, although interaction effects must be examined. An analysis with five studies also indicates that reinforcement does not harm intrinsic motivation. (SLD)

Through meta-analysis, 51 studies are examined in which interventions were aimed to enhance student learning by improving student use of either one or a combination of learning or study skills. Results obtained, through categorizing the interventions in hierarchical levels of structural complexity and as either near or far in terms of transfer,…

Reports the results of a meta-analysis that integrates research on undergraduate science, mathematics, engineering, and technology education since 1980. The meta-analysis of 39 studies demonstrates that various forms of small-group learning promote achievement, improve attitudes toward learning, and increase persistence in these fields. Contains…

Research on science education (case studies, cost-effectiveness estimates, surveys, and experiments), particularly for primary and secondary schools in low- and middle-income areas, is reviewed. Meta-analysis suggests that science education in developing countries can be made more productive. Effective ways of promoting science education are…
