This meta-analysis is the first to provide a quantitative synthesis of empirical evaluations of mathematical intervention programs implemented in secondary schools for students with learning disabilities and mathematics difficulties. Included studies used a treatment-control group design. A total of 19 experimental and quasi-experimental studies…

The purpose of this research was to systematically review the effects of repeated reading (RR) interventions on reading fluency to provide instructional strategies for students with reading disabilities (RD). Correct words per minute were coded as an outcome variable in a search that yielded 34 RR intervention studies from 1990 to 2014 for…

Mathematics anxiety is recognized as a significant performance impediment that affects students across multiple ethnic and economic backgrounds. However, research has yet to fully examine the possible differential effect of mathematics anxiety on underrepresented K-12 students. Specifically, given the long-standing achievement gap between African…

Among the protective factors associated with reduced risk for suicide, scientific inquiries into school connectedness are especially important considering that schools are ideally situated to provide interventions reaching the vast majority of youth. Although there is a wealth of research that supports the association between school connectedness…

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…

Researchers consider the underrepresentation of Black, Hispanic, and Native American students is largely due to the use of traditional methods of identification (i.e., IQ and standardized achievement tests). To address this concern, researchers created novel nontraditional identification methods (e.g., nonverbal tests, student portfolios,…

Over the past two decades, the number and types of after-school programs (ASPs) have increased substantially as a result of increased federal and private spending and because ASPs are perceived to provide wide-ranging and far-reaching benefits to students, families, schools and the public. The purpose of this systematic review and meta-analysis is…

The objective of the present study is to review the evidence on the effectiveness concerning the Saluda program, a school-based substance use prevention protocol used amongst adolescents. We provide a description of the program content and the results from nine controlled trials evaluating the program effectiveness. Participants were Spanish…

A meta-analysis was undertaken, including 66 studies, to determine the relationship between father involvement and the educational outcomes of urban school children. Statistical analyses were done to determine the overall impact and specific components of father involvement. The possible differing effects of paternal involvement by race were also…

To facilitate second language learning, it has become increasingly popular to use a second language as the medium of instruction for content subjects for majority language students. Although numerous research studies have shown the advantages of such kind of programs in North America and Europe, those investigating English as the Medium of…

Dynamic geometry software (DGS) aims to enhance mathematics education. This systematic review and meta-analysis evaluated the quasi-experimental studies on the effectiveness of DGS-based instruction in improving students' mathematical achievement. Research articles published between 1990 and 2013 were identified from major databases according to a…

Linking country-level educational achievement with other country-level indicators has the potential to drive systemic educational changes, as these correlates may reflect characteristics relevant for policy-making decisions to improve educational effectiveness. This study establishes a nomological network of educational achievement at the country…

Research on the use of software programs and tools such as pedagogical agents has peaked over the last decade. Pedagogical agents are on-screen characters that facilitate instruction. This meta-analysis examined the effect of using pedagogical agents on learning by reviewing 43 studies involving 3,088 participants. Analysis of the results…

The authors sought to (a) identify interventions that immediately increased the oral reading fluency of students with or at risk for disabilities, (b) estimate to what extent these gains maintained over time, and (c) evaluate whether particular characteristics of students (e.g., gender, disability status) predicted their response to fluency…

Results of a previous meta-analysis of gender differences in reading achievement at the secondary school level (Lietz, in press) showed significant differences between major assessment programs. Thus, the gender gap in favour of girls was more pronounced for the assessment programs conducted by the National Assessment of Educational Programs in…
