This paper presents evidence on the amount of classroom variation in gains across various domains of achievement within the Tennessee Voluntary Pre-Kindergarten (TN-VPK) program; the data are taken from the randomized control trial (RCT) design of the TN-VPK evaluation. This study explores areas where those differences are largest, and offers…

Of all the approaches to collecting data in the social sciences, the administration of questionnaires to respondents is among the most prevalent. Despite their popularity, there is broad consensus among survey design experts that using these items introduces excessive error into respondents' ratings. The authors attempt to answer the following…

Mental health among children and adolescents is a growing national concern and schools have taken center stage in efforts to prevent problems and promote wellness. Although research and policymakers support the integration of mental health services into the schools, there is limited agreement on the ways to package or combine existing supports to…

Researchers may have multiple motivations for combining disparate pieces of evidence in a meta-analysis, such as generalizing experimental results or increasing the power to detect an effect that a single study is not able to detect. However, while in meta-analysis, the main question may be simple, the structure of evidence available to answer it…

This study described the commenting practices of Head Start teachers, and the relationship of comments to the expressive and receptive vocabulary growth of children with below-the-mean language ability across one year of preschool. Participants included 52 Head Start teachers, and 489 children (247 early intervention candidates and 242 Head Start…

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and…

The present study examined the effectiveness of the oral history approach with respect to students' historical competence. A total of 35 ninth-grade classes (N = 900) in Germany were randomly assigned to one of four conditions--live, video, text, or a (nontreated) control group--in a pretest, posttest, and follow-up design. Comparing the three…

Children affected by parental HIV/AIDS are at-risk for poor school outcomes including reduced attendance, lower grades, and lower school satisfaction compared to unaffected peers. Resilience-based interventions offer promise to improve functioning across a number of domains. A four-arm randomized controlled trial was conducted with 790 children…

Purpose: The purpose of this paper is to discuss the findings of an intervention program built on the concept of children's health literacy, particularly on its citizenship component. This intervention program employed the Investigation-Vision-Action-Change model for action-oriented teaching, where children were supported to investigate different…

Background: Social relationships can serve as important risk or protective factors for child development in general, and academic adjustment in particular. Aims: This study investigated the role of teacher-child interactions in academic adjustment among preschool boys at risk of externalizing behaviour, using a randomized controlled trial study…

Adolescent girls are at substantial risk of sexually transmitted diseases including HIV. To reduce these risks, we developed Health Education And Relationship Training (HEART), a web-based intervention focused on developing sexual assertiveness skills and enhancing sexual decision-making. This study assessed the feasibility and acceptability of…

To systematically review experimental evidence regarding animal-assisted therapies (AAT) for children or adolescents with or at risk for mental health conditions, we reviewed all experimental AAT studies published between 2000-2015, and compared studies by animal type, intervention, and outcomes. Studies were included if used therapeutically for…

The achievement gaps between poor and more affluent students are persistent and chronic, as many students living in poverty are also members of more isolated communities where dialects such as African American English and Southern Vernacular English are often spoken. Non-mainstream dialect use is associated with weaker literacy achievement. The…

The use of cognitive-behavioural therapy (CBT) as a treatment for children and adolescents with autism spectrum disorder (ASD) has been explored in a number of trials. Whilst CBT appears superior to no treatment or treatment as usual, few studies have assessed CBT against a control group receiving an alternative therapy. Our randomised controlled…

Individuals with disabilities comprise the largest minority group in the world, yet they are the most underrepresented minority group in higher education, the job market and entertainment media such as literature. This population is often underrepresented because of the overlapping physical, attitudinal and policy barriers that prevent them from…
