There is a need for robust evidence about which educational interventions work in preschool to foster children's cognitive and socio-emotional learning (SEL) outcomes. Lab-based individually randomized experiments can develop and refine such interventions, and field-based randomized experiments (e.g., cluster randomized trials) evaluate their…

Cost-utility analyses are slowly becoming part of randomized control trials evaluating physical and mental health treatments and (preventive) interventions in child and adolescent development. The British National Institute of Health and Care Excellence, for example, insists on the use of gains in Quality Adjusted Life Years (QALYs) to compute the…

This report presents findings from exploratory, descriptive meta-analyses of effect sizes reported by the first 82 EEF evaluations that used a randomised controlled trial (RCT) or clustered RCT impact evaluation design published up to January 2019. The review used a theoretical framework derived from literature with five overarching themes to…

Background: The link between disorders of attachment and psychopathology is well documented. Consequently, a person's attachment style has a profound effect on his or her development and psychological well-being. At-risk populations such as adopted children are more prone to developing pervasive patterns of attachment, given the maternal…

Persons with mental illness smoke at rates two to four times higher than do persons without mental illness and comprise 30.9% of the U.S. tobacco market. Given the prevalence of mental illness and the known detrimental effects of tobacco, concerted efforts are needed to promote the use of evidence-based treatment options. We conducted a systematic…

There are concerns that too many young people, from disadvantaged backgrounds, are moving into secondary education in the UK, and elsewhere, without the necessary literacy skills to make progress with the wider secondary school curriculum. A large number of interventions have been proposed to reduce this poverty gradient. This paper summarises the…

Individuals with traumatic brain injury (TBI) often struggle to obtain competitive employment after sustaining a TBI, commonly as a result of the post-injury difficulties they exhibit (Andelic, Stevens, Sigurdardottir, Arango-Lasprilla, & Roe, 2009; Mansfield et al., 2015). The currently reported unemployment rate for people with TBI is…

Understanding the effects of class size reduction (CSR) has been an enduring issue in education. For the past 3 decades, Project STAR has stimulated research and policy discussions regarding the effects of CSR on a variety of outcomes. Schanzenbach (2007) reviewed STAR studies and concluded that small classes improved student academic outcomes.…

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar,…

This meta-analysis summarizes research on the effects of a comprehensive, interactive web-based software (AXXX) on the development of reading competencies among kindergarteners and elementary students. Findings from seven randomized control trials and quasi-experimental studies undertaken in a variety of contexts across Canada, Australia and Kenya…
