This study is a meta-analysis of the effects of out-of-school time (after school, summer camps, enrichment programs, etc.) on the student interest in STEM. This study was guided by the following research questions: (1) How effective is OST as a means to foster student interest in STEM? (2) How does the effectiveness of OST differ by program and…

Raising the literacy levels of young children is a major concern in many countries for which various programmes have been suggested. One of these is family literacy programmes. In previous meta-analyses wide variability in effects has been found and it has been suggested that this is partly caused by variability in implementation quality. This…

Mobile technology has become ubiquitous in the education and support of individuals with disabilities. While this practice is supported under the Universal Design for Learning framework, research in the area has yet to establish a solid evidence base. The majority of the studies in existence are single-subject design studies with a dearth of…

This review of research analyzed topics, conceptual models and research methods employed in 62 EDLM studies from Arab societies published between 2000 and 2016. Systematic review methods were used to identify relevant studies published in nine core international EDLM journals. Quantitative analyses identified patterns within this set of Arab…

The focus of this article is on the use of theories and on what we imply when we in research claim to use a theory. In this article, diverse uses of one theory will be illustrated with reference to 10 different studies. The aim is not to evaluate or judge how the theory is used in these studies, but to discuss how the diverse uses of one and the…

The purpose of this study was to provide an updated content analysis of articles published in major journals of school psychology spanning the years 2010-2014, with an emphasis on intervention research (including intervention and participant characteristics). Six journals--"School Psychology Review," "School Psychology…

In this article, we review the literature on the impact of family literacy programmes on young children's language and literacy learning. After defining family literacy, we present a brief historical overview of family literacy programmes, including persistent questions regarding their effectiveness with respect to young children's language and…

This study examined the relationship of Problem-based Learning (PBL) and medical students' attitudinal behavior and academic outcomes. The analyses of 14 independent, primary studies conducted between 2003-2016, on 4,981 medical students across various medical schools were included in the study. The data were examined using a meta-analysis…

Recently, researchers have begun associating personal epistemology with self-regulated learning. Therefore, in the literature there is a need to examine what degree the studies have supported the relationship between the two. The purpose of this meta-analysis is two folds: a) to compute the mean effect size for the relations between personal…

Group social skills interventions (GSSIs) are a commonly offered treatment for children with high functioning ASD. We critically evaluated GSSI randomised controlled trials for those aged 6-25 years. Our meta-analysis of outcomes emphasised internal validity, thus was restricted to trials that used the parent-report social responsiveness scale…

In this article, we trace the development of the Campbell Collaboration and its renewed efforts to build a world library of accurate, synthesized evidence to inform policy and practice and improve human well-being worldwide. Campbell systematic reviews and related evidence synthesis products provide unbiased summaries of entire bodies of empirical…

Being overweight or obese (overweight/obesity) or physically aggressive in childhood and adolescence can have lifelong consequences, hence are important public health problems. Identifying a relationship between these problems would assist in understanding their developmental origins. The present paper sought to review previous studies and use…

Purpose: This paper aims to test a nudge, or intervention, designed through behavioral insights at a university campus to discover cost-effective means for increasing recycling participation and methods for estimating waste removal cost savings. Design/methodology/approach: A series of studies were conducted demonstrating the effectiveness of…

The Implicit Association Test (IAT) is increasingly used in developmental research despite minimal evidence of whether children's IAT scores are reliable across time or predictive of behavior. When test-retest reliability and predictive validity have been assessed, the results have been mixed, and because these studies have differed on many…

Although their research agendas may vary widely, school library researchers from around the world share the common goal of conducting studies designed to advance the field of school librarianship. International school library scholars are united in their efforts to prove that quality school library programs can have a significant impact on student…
