The extent to which youth attend Tier 2 evidence-based intervention is an important dimension of implementation. This study examined attendance patterns of 369 middle schoolers involved in a randomized trial testing the impact of Coping Power, an evidence-based Tier 2 preventive intervention. We conducted latent profile analysis to examine student…

In paired experiments, participants are grouped into pairs with similar characteristics, and one observation from each pair is randomly assigned to treatment. The resulting treatment and control groups should be well-balanced; however, there may still be small chance imbalances. Building on work for completely randomized experiments, we propose a…

This exploratory study expands the literature on teachers' natural use of praise and reprimand, in terms of how teachers deliver praise and reprimand. Sixty-six middle and high school teachers' delivery of praise and reprimand to individual, small groups, and large groups during a 20-min observation were examined. Teachers delivered significantly…

Miami, Florida has the highest percentage of foreign-born residents in any large US metropolis and is characterized by Caribbean culture and economic practice in a way that is unseen in many other US cities. Haitian immigrants have been flowing rapidly into historically African American communities since the 1970s. Adults who grew up in these…

Research in this study investigated the effectiveness of robotics in promoting the critical thinking skills of middle school students in a public school classroom setting. The research began with an analysis of the effect of educational robotics in improving the critical thinking skills of middle school students. The researcher then sought to…

Many schools use paraprofessionals to implement and monitor interventions. Though paraprofessionals are cost-effective, many questions remain about the training and skills they need to implement a wide array of school-based interventions. In this study, we compare paraprofessionals' (i.e., undergraduates) implementation of the Group-Academic…

This study investigates learners' perceptions of the benefits and the difficulties of group work (GW) in EFL (English as a foreign language) classes. The purpose of this study is to explore the possible effects of GW, in order to better understand learners' attitudes towards GW, and to inform language teachers of students' views of using GW. A…

This study examines the use of an explicit, reflective method for teaching the difference and relationship between scientific theories and laws to ninth-grade students. Students reflected individually and then as a whole class on theories and laws using a Venn diagram, both before and after reading short articles describing features of theories…

I examined students' discourse while working in pairs at the computer in an eighth-grade mathematics class to understand how students kept track of the people and things they discussed. I found that students most often referenced themselves and objects within the environment, through references to shared knowledge and the representations on the…

This paper presents first results from a research project aimed at combining two theoretical frameworks, one concerning explanations and one related to rationality. The two theoretical lenses are used to understand one episode from a teaching experiment carried out in grade seven, concerning the construction of rectangles with a given perimeter.…

Group mentoring is an increasingly popular intervention, but is still under-studied. This article reports findings from a qualitative study of the Young Women Leaders Program (YWLP), a combined group and one-on-one mentoring program for early adolescent girls. Protégés (n = 113) were interviewed post-program about changes they made as a result of…

This paper originates from a study conducted to examine the challenges faced by the Schools for Special Education (SLB) in their effort to empower people living with disabilities. The study aimed: 1) to describe the stages involved in the education for empowerment of the disabled groups through schools for special education, 2) to present an…

This study examined a large, nationally-representative sample of eighth-grade students in the US to assess how the frequency of group learning activity in mathematics classrooms was associated with mathematics achievement and three measures of attitudes toward mathematics. Results showed that moderate amounts of group work in class had positive…

A growing program of research in science education acknowledges the beginnings of disciplinary reasoning in students' ideas and seeks to inform instruction that responds productively to these disciplinary progenitors in the moment to foster their development into sophisticated scientific practice. This dissertation examines secondary school…
