In this study, we estimated the cost of implementing the Self-Determined Learning Model of Instruction (SDLMI), an evidence-based practice in secondary transition, at scale in 17 U.S. school districts to enhance self-determination and transition goal attainment outcomes among 340 transition-age adolescents with intellectual disability. An…

Student achievement disparities in inclusive science classrooms are concerning, as knowledge about science, technology, engineering, and mathematics (STEM) is increasingly important for upward mobility. When students identify with multiple marginalized sociocultural groups, progress becomes more troubling, as the interplay among these factors is…

Professional development (PD) is one way to maintain or increase teacher effectiveness in any number of domains. However, PD comes in many formats and with a wide range of evidence on its effectiveness -- both of which can shape teachers' perspectives of the PD even before they participate. The purpose of this research was to examine how…

The literature review in this dissertation examined what writing intervention strategies have been implemented with high school students in special education, with what measures, and with what found outcomes. The study following the literature review surveyed and interviewed high school special education teachers to determine what practices the…

Evidence-based instructional strategies in mathematics provide critical support related to academic achievement for students with disabilities. Data from national achievement assessments suggest that students with disabilities' academic growth in mathematics stagnates at the secondary level. Given that the majority of previously researched…

Knowledge of instructional strategies in cotaught K-12 classrooms raises awareness of this unique collaboration for benefitting students with disabilities. The purposes of this qualitative study were to (1) identify pedagogical strategies that facilitate coteaching in inclusive environments and (2) explore the relevance of coteaching teams and…

The need for well-implemented evidence-based interventions (EBIs) for the prevention of behavioral issues among children and adolescents is substantial. In rural areas, the need often matches or surpasses that of urban areas. Schools have a wide reach for prevention-focused EBIs. However, implementation in rural schools is often hindered by…

Post-training consultation support is linked to improvements in evidence-based treatment fidelity following initial training, but little is known about what makes it work, and how clinician-level factors may moderate its effects. This study examined the adherence and competence of N = 33 school-based clinicians trained to provide modular Cognitive…

The quality of interventions for children with autism has improved thanks in part to the widespread dissemination of evidence-based practices (EBPs); however, teachers still report challenges developing focused interventions targeting the core challenges of students with autism. Tested in three randomized trials, COMPASS is a consultation-based…

Large-scale, evidence-based interventions face challenges to program fidelity of implementation. We developed implementation strategies to support teachers implementing an evidence-based HIV prevention program in schools, Focus on Youth in The Caribbean (FOYC) and Caribbean Informed Parents and Children Together (CImPACT) in The Bahamas. We…

Check-in/check-out (CICO) is an evidence-based practice for addressing the behavioral needs of students with and without disabilities from kindergarten through the 12th grade. The CICO intervention is easily adapted to address other areas of need, beyond behavior, including academics and social integration, making CICO appealing for all school…

Making connections within and between different aspects of mathematics is recognised as fundamental to learning mathematics with understanding. However, exactly what these connections are and how they serve the goal of learning mathematics is rarely made explicit in curriculum documents with the result that mathematics tends to be presented as a…

Infrared (IR) technologies have been universally acknowledged as a valuable pedagogical tool for exploring novel and abstract scientific subjects in science education. This study explores the roles of IR images played in middle school students' Evidence-based Reasoning (EBR) process in support of the understanding of the heat radiation process.…

The problem that guided this study was the low proportion of students scoring 3 or more on the Advanced Placement English Language and Composition (APELC) exam at one Department of Defense (DoD) school. Moreover, the qualifying ratios were lower than students attending all DoD and U.S. schools. The need for teachers to examine the performance of…
