Academically talented students with autism, also known as twice-exceptional students with autism (2eASD), are increasingly identified in school. These students present challenges to educators who attempt to plan and implement successful instructional opportunities, as teachers' knowledge and use of evidence-based practices (EBPs) for students…

This convergent parallel mixed-methods study examines the relationship between high school mathematics teachers' research-based instructional practices and students' learning outcomes in Algebra 1 classrooms at a high school in a central region of a Southern U.S. State. The research addresses improving mathematics proficiency in the United States,…

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…

This study explores the efficacy of the Math Workshop Model in enhancing the capacity of secondary mathematics teachers to differentiate instruction, implement equitable teaching practices, and meet the diverse needs of students in mixed-ability classrooms. Through a mixed methods approach, including classroom observations, interviews, and surveys…

This qualitative historical single-case study examines how a practitioner-directed approach to professional development for teachers resulted in successful technology integration in a newly unified school district in California's Central Valley. The study details the process of creating and implementing a professional development plan for newly…

Adapting and combining evidence-based practices (EBPs) for use in high school special and general education in support of autistic youth can be a daunting process for researchers and practitioners alike. Ensuring the process is informed by autistic voices, is strengths-based, and addresses outcomes identified as priorities for autistic youth can…

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…

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…

We investigated the receptive American Sign Language (ASL) skills of four separate groups using the 42-item ASL-Receptive Skills Test: Deaf high school-aged students who attended a residential school; deaf incoming college students who preferred signed language; deaf incoming college students who preferred spoken language; and typically hearing…

The Mathematics Teaching Practices identified by the National Council of Teachers of Mathematics are eight research-based practices that promote mathematics teachers' implementation of specific knowledge to support student understanding. We wondered which practices mathematics teachers perceived as most characteristic and least characteristic of…

Teaching resources and professional development based on mathematics education research have the potential to support teachers to develop and sustain improved pedagogies. The Queensland Department of Education provided online professional learning modules for teachers of Prep (Foundation) to Year 10 mathematics. To support implementation of the…

Despite national curricula and instructional reforms calling for collaborative problem-solving skills (CPS), however, there is an absence of a theory-laden model showing how to effectively construct CPS for science learning. We therefore developed and validated a simulation-based CPS model that exploits its constructs, sequences, and causal…

High school graduates should be able to read to complete everyday tasks. Without this ability, their quality of life could decline from the lack, a negative mindset, or both. Therefore, educational stakeholders aiding students with reading struggles must find the most effective solutions for these students. Students achieving below-average on…

Background: The research-practice gap has not been explored within civics education, and in particular the role of evidence-based civics curriculum in times of political trauma. Such research is critical in equipping educators with evidence-based resources to help mitigate political trauma experienced by students. Here, we explore the types of…

Students with mild intellectual disabilities need explicit vocabulary instruction with multiple exposures in different contexts and extra practice in associating meanings to unfamiliar words to build their word knowledge. The purpose of this study was to examine the effect of multimedia-based computer assisted instruction on learning the meanings…
