In the present meta-analysis, we systematically examined the association between students' initial level of metacognition and their academic achievement at least three months later. Using multilevel meta-analysis as well as meta-analytic structural equation modelling, we analysed data from 71,171 students provided by 28 independent studies. The…

Although convergent research demonstrates that well-designed graphics can facilitate readers' understanding of text, there are select situations where graphics have been shown to have no effect on learners' overall text comprehension. Therefore, the current meta-analytic study examined 39 experimental studies published between 1985 and 2018…

Since the standards-based education movement began in the early 1990s, mathematics education reformers have developed and evaluated many interventions to support students in mastering more rigorous content. We conducted a systematic review and meta-analysis of U.S. PreK-12 mathematics intervention effects from 1991 to 2017 to study sources of…

Second language (L2) anxiety has been the object of constant empirical and theoretical attention for several decades. As a matter of both theoretical and practical interest, much of the research in this domain has examined the relationship between anxiety and L2 achievement. The present study meta-analyzes this body of research. Following a…

The purpose of this meta-analytic review was to investigate the relation between motivation and reading achievement among students in kindergarten through 12th grade. A comprehensive search of peer-reviewed published research resulted in 132 articles with 185 independent samples and 1,154 reported effect sizes (Pearson's r). Results of our…

In this analysis of extant data from 3,011 schools implementing school-wide positive behavioral interventions and supports (SWPBIS) across multiple years, we assessed the predictive power of various school characteristics and speed of initial implementation on sustained fidelity of implementation of SWPBIS at 1, 3, and 5 years. In addition, we…

This study examined the effects of teacher characteristics, school conditions, teacher efficacy, external support, and remuneration on music educators' risk for attrition and migration. Data from the 1999-2000 Schools and Staffing Survey--a comprehensive, nationally representative survey of teachers, principals, and schools conducted by the…

This article reviews 34 studies in reading research. It identifies trends related to ambiguous findings about the effect of sentence-combining training on measures of reading comprehension. The effects of grade level and four other variables are described. The use of cloze procedures and standardized tests as measures is discussed. (Author/JL)

Using analysis of variance and regression techniques, the authors analyzed the results of 40 studies that were conducted between 1953 and 1976 and contained 232 correlations between various measures of motivation and achievement. The motivation variables were restricted to students' achievement motivation, locus-of-control perceptions, and general…
