Research has demonstrated positive impacts of behavioral interventions on various educational outcomes for autistic youth, and implementation of these interventions in education settings has been widely advocated. However, recent studies have identified methodological shortcomings in the behavioral intervention evidence base, including lack of…

Every year, an increasing number of autistic youth enter a complex and underfunded adult service system after graduating from high school. Executive function (EF) challenges commonly co-occur with autism, especially related to flexible problem-solving and planning, and are linked to poor outcomes in post-secondary education and employment. The…

There is a lack of research on evidence-based intervention in relation to the issue of L2 variations in secondary schools. This study addresses some conceptual problems of L2, proposing a four-quadrant model of language processes. This model provides a framework to identify students' L2 developmental stages. With an action research method, the…

Teachers often receive little formal training in how to effectively intervene when a student is behaving in a non-productive manner. Research shows that punitive consequences are usually not effective and are connected to negative outcomes for students. This study aimed to provide teachers with a working knowledge of Scott and Colvin's…

I conducted a single instrumental case study to address the problem of practice in which approximately one-third of students entering the ninth grade for the 2019-2020 school year in the study school district were reading below grade level proficiency. I chose an instrumental case study method because it allows for an in-depth examination of a…

The final year of secondary school has been shown to be associated with heightened student stress. Psychological interventions have been shown to be effective in reducing and preventing distress in students during this school period, although the widespread adoption of these interventions into school settings is limited. There have been recent…

Peer-mediated interventions are an evidence-based practice for enhancing the social and learning outcomes of students with autism and other developmental disabilities. However, little is known about the peers who participate in these interventions or the ways they are impacted through their involvement. In this pilot study, we examined changes in…

Literacy skills are instrumental to unlocking a child's full potential and have a well-established link to long-term life outcomes. Children who can't read at grade level by 3rd grade are four times more likely to drop out of school, have fewer career prospects, and earn lower incomes as adults. However, despite some progress on literacy rates,…

One core feature of Positive Behavioral Interventions and Support (PBIS) is a systems-level teaming process for coordinating staff implementation of evidence-based practices and monitoring student progress across all three tiers. Prior research has shown schools that report regular teaming and team-based data use are more likely to successfully…

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…

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…

This protocol guided the review of research that informs the What Works Clearinghouse (WWC) practice guide entitled "Strategies for Postsecondary Students in Developmental Education -- A Practice Guide for College and University Administrators, Advisors, and Faculty." This protocol was used in conjunction with the "WWC Procedures…

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…

As part of a multiyear research project investigating the affordances of online citizen science (OCS) projects for enhancing school students' learning in relation to science and digital technology, teacher-researchers have designed and implemented classroom interventions incorporating one or more OCS projects. The project is situated in New…

High schools hold great potential as contexts within which educators implement evidence-based practices shown to change post-school outcomes for youth with autism spectrum disorder (ASD). Unfortunately, educators feel unprepared to use transition and disability-focused evidence-based practices. Coaching, as an essential feature of effective…
