Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

Purpose: To advance the study of principal time use (PTU), the purpose of this study is to report findings from a systematic review of PTU research. In addition to identifying common findings, this study also examined the supporting evidence and methodologies of PTU studies. From this dual approach, this study specified the evidence that supports…

Problematic smartphone use has become a global problem with broad implications for education. The present meta-analysis studies the relationship between problematic smartphone use and procrastination in students. A literature search was conducted in Web of Science, PsycInfo and Scopus databases, obtaining a total of 18 articles that met the…

Students have misconceptions about many scientific topics they encounter in the classroom--such misconceptions are especially rife in subjects with counterintuitive concepts. Several studies have copiously documented students' misconceptions in different science domains. Research shows that students' misconceptions can be resistant to change and…

An ongoing debate points to a possible gap between the published research about and the delivery of leisure services. For example, two of the major research journals in the field of leisure studies, "Journal of Leisure Research" ("JLR") and "Journal of Parks and Recreation Administration" ("JPRA"), are…

Self-handicapping is a maladaptive strategy that students employ to protect their self-image when they fear or anticipate academic failure. Instead of increasing their effort, students may harm their chances of success by procrastinating, strategically withdrawing effort, or engaging in destructive behaviors like drug abuse, so that potential…

Objective: College students with attention-deficit/hyperactivity disorder (ADHD) and/or a learning disorder (LD) are at higher risk for not attaining a bachelor's degree. The purpose is to identify the predictors of academic success in college for students with ADHD and/or LD using a systematic review of the literature. Method: Academic Search…

In this research, the effects of cooperative learning on mathematics achievement in Turkey were examined by meta-analysis method. For this purpose, the average effect size value and the average effect size values of the moderator variables (cooperative learning technique, education level, learning domain and implementation period) were calculated.…

In experimental research, internal validity refers to what extent researchers can conclude that changes in dependent variable (i.e. outcome) are caused by manipulations in independent variable. The causal inference permits researchers to meaningfully interpret research results. This article discusses (a) internal validity threats in social and…

Promoting students' critical thinking skills is an important task of higher education. Colleges and universities have designed various instructional interventions to enhance students' critical thinking skills. Empirical studies have yielded inconsistent results in terms of the effects of such interventions. This meta-analysis presents a synthesis…

Increased accountability in education has resulted in a focus on implementing interventions with strong empirical support. Both student outcome and treatment integrity data are needed to draw valid conclusions about intervention effectiveness. Reviews of the literature in other fields (e.g., applied behavior analysis, prevention science) suggest…

This meta-analysis examined the influence of attributes related to the implementation of learning strategy instruction interventions on students' academic performance, and also examined how the attributes related to the method of testing the intervention effects affected the actual effects measured. Using metaregression, we analyzed the…

This chapter introduces theory that undergirds the role of testing adaptations in assessment, provides examples of item modifications and testing accommodations, reviews research relevant to each, and introduces a new paradigm that incorporates opportunity to learn (OTL), academic enablers, testing adaptations, and inferences that can be made from…

The purpose of this study was to examine the college enrollment and persistence rates of rural high schools in Pennsylvania; the types of postsecondary institutions in which students from such schools enroll; and the student, school, and college characteristics associated with enrollment and persistence outcomes. The study used extant data from…

The purpose of this brief is to provide information to state, district, and school personnel seeking support to determine whether their students are on a path to postsecondary success. The College and Career Readiness and Success Center (CCRS Center) has received technical assistance requests from a number of states regarding factors that predict…
