The What Works Clearinghouse (WWC) Standards Briefs explain the rules the WWC uses to evaluate the quality of studies for practitioners, researchers, and policymakers. This brief explains what baseline equivalence is and why it matters. As part of the WWC review process for certain types of studies, reviewers assess whether the intervention group…

Purpose: The purpose of this study was to determine whether, and how, electricity consumption by students in university residence halls were impacted through three intervention strategies. Design/methodology/approach: The current investigation uses a quasi-experimental design by exposing freshman students in four matched residence halls and the…

Gaps in education attainment between high and low achieving children in the primary school years are frequently evidenced in educational reports. Linked to social disadvantage, these gaps have detrimental long-term effects on learning. There is a need to close the gap in attainment by addressing barriers to learning and offering alternative…

The field of language teaching and learning is in dire need of replications of vocabulary and comprehension research with diverse populations of learners. We propose for replication one large-scale vocabulary intervention carried out successfully in a middle-school with monolingual and multilingual students. This study was carried out several…

This dissertation portfolio is comprised of three first-authored pieces of writing that investigate the oral language and emergent literacy development of Spanish-speaking children with specific language impairment (SLI). Each piece features a unique but complementary aim. The first study investigates group differences on a battery of emergent…

Background: Children with chromosome 22q11.2 deletion syndrome (22q11DS) often have deficits in social cognition and social skills that contribute to poor adaptive functioning. These deficits may be of relevance to the later occurrence of serious psychiatric illnesses such as schizophrenia. Yet, there are no evidence-based interventions to improve…

Background: Translating research findings into practice should be one of the objectives of developmental psychology. Recently, research demonstrated the existence of individual differences in theory of mind (ToM) during middle childhood that are crucial for children's academic and social adjustment. Aims: This study aims to transfer the results of…

Misconceptions of psychological phenomena are widespread and often not easily eliminated--even among students completing college-level psychology courses. As part of a research methods psychology course, students developed public-service-announcement-style posters as part of a psychology myth-debunking campaign and presented these to students…

To evaluate the relative efficacy of two reading programs with and without adjunctive stimulant medication for children with attention-deficit/hyperactivity disorder and comorbid reading disorder (ADHD+RD). Sixty-five children (7-11 years in age) were assigned randomly to one of three intensive remedial academic programs (phonologically or…

Background: Young children are often required to carry out writing tasks in an educational context. However, little is known about the patterns of writing skills that children with specific language impairment (CwSLI) have relative to their typically developing peers. Aims: To assess the written language skills of CwSLI and compare these with…

The study reported here involved Cooperative Extension as a key research partner and was guided by a community-based participatory research approach and a feasibility study framework. The research objective was to assess four indicators of feasibility (i.e., acceptability, demand, implementation, and limited-effectiveness) of a gardening and…

There are no known biomedical or genetic markers to identify which infants with galactosaemia (GAL) are most at risk of poor language skill development, yet pre-linguistic communicative "red flag" behaviours are recognised as early identifiers of heightened vulnerability to impaired language development. We report on pre-linguistic…

The purpose of this study was to examine the influence of the social context, based within self-determination theory, on student's in-class physical activity. A total of 84 Year 11/12 physical education students were randomly assigned to one of three treatment groups; Autonomy-supportive, Controlling and Balanced. Data were collected using a…

Many individuals endorse feminist values but do not identify as feminist. The present set of studies tests the concept of threat, grounded in G. A. Kelly's personal construct theory of personality, as a potential factor in feminist nonidentification. Study 1 introduces the theoretically grounded "Feminist Threat Index" and evaluates its…
