This study investigates the use of GeoGebra, a Dynamic Geometry Software (DGS) for math learning in Virtual Reality (VR) using head-mounted displays. We conducted a study with n = 20 middle school students receiving a mathematics tutoring intervention over time in a VR environment. Using theories of embodied cognition and playful mathematics, this…

This dissertation closely examines the model of a suburban northern Delaware alternative program. The researcher determined how well this program successfully prepared 52 scholars to successfully transition forward into a comprehensive school. Each student in the study was removed from the comprehensive school and enrolled into the alternative…

In this systematic evaluation of intervention research for transition-age autistic youth, we examined quality indicators in 193 group and single-case design intervention studies, which tested effects on 1258 outcomes. Behaviorally based interventions were the most common intervention type. We found significant threats to internal validity for the…

This study used a multiple probe design to evaluate the effects of a teacher-implemented video-schedule intervention on the mathematical skills and untargeted challenging behaviors of five elementary-school students with autism. Results indicated that the intervention was effective in improving participants' academic performance, and a decrease in…

The Faith and Wellness: A Daily Mental Health Resource is a school-based, teacher-led social-emotional learning (SEL) intervention resource for elementary students. It is designed to address the challenges faced by existing SEL interventions, including lack of time, training, and resources. Using a randomized control trial design, this study…

Gaps in advanced high school coursework by socioeconomic status and geography persist in the United States, even among students with the ability and access to succeed in them. Lack of information on course availability and inaccurate self-perceptions may contribute to these inequities. We report on a large-scale experiment designed to increase…

Purpose: This systematic review aimed to identify studies evaluating the impact of high-intensity interval training when delivered in school and sports training. Methods: A systematic search of 10 databases (September 2019) identified 24 eligible studies (including children and/or adolescents 5-18 years and reporting cardiometabolic health and/or…

Autistic children commonly experience mealtime difficulties; however, it is unknown what makes an effective transdisciplinary mealtime service for autistic children. This study used a realist evaluation framework to explore caregivers' and therapists' perceptions of the contexts, mechanisms and associated outcomes of a transdisciplinary mealtime…

Despite increased diagnostic prevalence, Black parents raising autistic youth still experience additional and unique barriers to accessing and using autism-related services compared to their non-Black peers. Increasing parent advocacy capacity may be one way to reduce these disparities. This efficacy study examined the effects of the FACES…

U.S. Department of Education research indicates that early warning indicator systems are being used in at least half of high schools in the United States. Previous findings from an efficacy study of one early warning indicator and response system, the Early Warning Indicator (EWI) team model, indicated that ninth grade students in schools using…

The current study aimed to qualitatively explore participants' perceived effectiveness of the UWorkItOut UWin program (a six-week exercise and counseling intervention) as well as the perceived outcomes. Previous research has found the UWorkItOut UWin program to be effective at decreasing psychological distress in university students. Exit…

School social workers are integral to the school mental health workforce and the leading social service providers in educational settings. In recent decades, school social work practice has been largely influenced by the multi-tiered systems of support (MTSS) approach, ecological systems views, and the promotion of evidence-based practice.…

The use of speech-generating devices (SGD) in early interventions for children with autism spectrum disorder (ASD) can improve communication and spoken language outcomes. The purpose of this study was to describe children's responsiveness to SGD input modeled by a social partner during adult-child play interactions over a 24-week intervention…

Interventions to develop functional capacity for children with developmental difficulties have tended to be therapist driven. Such approaches can present difficulties for parents who describe increased stress and feelings of incompetence in a paradigm that can feel imposed. Recent findings have questioned the efficacy of the approach, given a…

Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…
