The sample consisted of 208 predominantly African American low-income children with a mean age of 48.8 months. A quasi-experimental design was used in which 7 classrooms had…

This study focused on effects of high-ability programs on students' achievement emotions, i.e. emotions that students experience that are associated with achievement activities. Participants were students in grade 4-6 of primary education: 218 students attended full-time high-ability programs, 245 attended part-time high-ability programs (i.e.…

A mixed methods approach was applied to examine the effects of a naturally occurring teamwork intervention supported with training. The first objective was to integrate qualitative process evaluation and quantitative effect evaluation to examine "how" and "why" the training influence intervention outcomes. The intervention (N =…

While randomized experimental designs are the gold standard in education research concerned with causal inference, non-experimental designs are ubiquitous. For researchers who work with non-experimental data and are no less concerned for causal inference, the major problem is potential omitted variable bias. In this presentation, the authors…

This study investigates: (1) how principals' data-driven practices may vary by principals' and school backgrounds and how that changes over time; (2) how principals' data-driven practices influence teacher buy-in; and (3) how principals' data-driven practices and teachers' buy-in influence student outcomes. This study uses data from the Study of…

Background/Context: Most reforms in elementary education rely on teacher learning and improved instruction to increase student learning. This study increases our understanding of which types of professional development effectively change teaching practice in ways that boost student achievement. Purpose/Objective/Research Question/Focus of Study:…

This study examines whether the Communities That Care (CTC) prevention system influences targeted risk and protective factors and the subsequent development of problem behaviour among adolescents (12-18 years) in the Netherlands. In this quasi-experimental study of ten communities (five experimental, five control), adolescent outcomes were…
