Second language (L2) learners' beliefs about the nature of language learning, specifically language mindsets, is a recent productive line of L2 research. Researchers argue that language mindsets are key factors for language learning success. However, the association between language mindsets and different language learning outcomes is inconsistent…

Previous research evaluating behavior skills training and performance feedback has largely examined factors influencing interventionist performance outcomes. However, to our knowledge, researchers have yet to compile existing literature to specifically explore characteristics associated with improved learner outcomes in the context of…

Background: Inclusive STEM high schools seek to broaden STEM participation by accepting students on the basis of interest rather than test scores and providing a program sufficient to prepare students for a STEM major in college. Almost nonexistent before the present century, these high schools have proliferated over the last two decades as a…

Students' academic achievement is a central predictor of a long list of important educational outcomes, such as access to higher education and socioeconomic success. Prior studies have extensively focused on identifying variables that are related to academic achievement and an important variable in this context appears to be students' personality.…

The infusion and diffusion of the interactive whiteboard (IWB) has attracted considerable interest in educational contexts over the past years. However, research to date has been controversial with regard to the effectiveness of IWB-based instruction on cognitive learning outcomes. This study identified empirical publications that examine…

This meta-analysis intends to determine the impact of cooperative learning model research findings on the mathematics learning outcomes of Indonesian vocational high school students. Based on moderator variables, such as grade level and student sample size, identify efficacy and publication bias measures. Data from descriptive analysis, which…

This meta-analysis of 28 studies examines the relationship between parental involvement and the academic achievement and school behavior of Latino pre-kindergarten-college-age children. Analyses determined the effect sizes for parental involvement overall and specific categories of involvement. Results indicate a significant relationship between…

The current meta-analysis examined the use of deep touch pressure (DTP; e.g., weighted vests) with students with disabilities. DTP is a form of sensory integration therapy that is currently used extensively in schools with students with autism and other disabilities. Each study in the analysis was evaluated using the Council for Exceptional…

Students with disabilities experience poorer post-school outcomes compared with their peers without disabilities. Existing experimental literature on "what works" for improving these outcomes is rare; however, a rapidly growing body of research investigates correlational relationships between experiences in school and post-school…

Interventions based on the results of functional behavioral assessment (FBA) have been the topic of extensive research and, in certain cases, mandated for students with disabilities under the Individuals With Disabilities Education Act. There exist a wide variety of methods for conducting such assessments, with little consensus in the field. The…

A new effect size representing the predictive power of an independent variable from a multiple regression model is presented. The index, denoted as r[subscript sp], is the semipartial correlation of the predictor with the outcome of interest. This effect size can be computed when multiple predictor variables are included in the regression model…

When conducting a meta-analysis, it is common to find many collected studies that report regression analyses, because multiple regression analysis is widely used in many fields. Meta-analysis uses effect sizes drawn from individual studies as a means of synthesizing a collection of results. However, indices of effect size from regression analyses…

This meta-analysis was performed to determine the overall effectiveness of computer assisted instruction on students' academic achievement in science education from 2001 to 2007 in Turkey. The study reported the results of 65 effect sizes (ES) included in 52 studies. Grand mean for 65 ESs was found to be 1.12. This effect size can be interpreted…

Current quantitative research on the effectiveness of the National Board certification has resulted in contradictory findings. Consequently, this meta-analysis synthesized the results of 12 studies on National Board Certification and student achievement. Of those, 9 studies were used to calculate effect sizes for reading, and all 12 were used to…

Research on the validity of psychosocial factors (PSFs) and other noncognitive predictors of college outcomes has largely ignored the practical benefits implied by the validity. We summarize evidence of the validity of PSF measures as predictors of college outcomes and then explain how this validity directly translates into improved identification…
