Sensory processing difficulties (SPD) can significantly impact a child's behavior, learning, and overall well-being. However, many educators, particularly those teaching in the early grades, lack the necessary training to recognize and effectively respond to these challenges. Consequently, students exhibiting atypical behaviors are often…

Understanding human behavior and reasoning is essential for developing successful instruction. Discipline-based education researchers have examined how students learn, informing the development of successful instructional strategies. Researchers have also identified barriers to the successful implementation of such strategies. This work utilizes…

Improving education, particularly for the sciences, is an important and necessary endeavor which can lead to positive social change. Education reform tends to involve updating and aligning curriculum standards without considering methodologies or teaching strategies involved. Identifying evidence-based practices to improve achievement in science,…

This action research study aimed to find ways to adjust my practice by incorporating inquiry-based, science activities and virtual simulations to improve student conceptual understanding of physical and chemical changes. A multi-lesson, curricular intervention combining inquiry-based activities and virtual simulations was developed using…

Engineering education has a long and well-researched history; however, recent declines in the number of undergraduate students entering and matriculating through to graduation has commanded the engineering education community's attention. To help counter the declining number of students entering and persisting in engineering, an engineering…

Background: Higher education is more diverse than ever with a drastic increase in college enrollment over the past two decades by those who have not traditionally sought undergraduate credentials, including students with disabilities (Espinosa, Turk, Taylor, & Chessman, 2019; Clouder et al., 2020). Despite the growing demographic diversity of…

More than 85% of federally funded research initiatives fail to produce significant positive results (Coalition for Evidence-Based Policy, 2013). Moreover, of the less than 15% that do yield positive results, none show replicability outside of their original setting (Pogrow, 2017; Kizilcec et al., 2020). Mixed results are present in even the most…

Statistics connected to the national workforce demand for science, technology, engineering, and mathematics (STEM) graduates, and the apparent shortage of these graduates is staggering. Internet data reveal that by 2020 there will be 1.4 million computer-science-related jobs and only about 400,000 computer science graduates who have the skills…

It has been well-establishing in the field of educational research that traditional educational methods such as passive lectures and labs where students follow pre-designed procedures to verify information already told to them are not effective for promoting meaningful and lasting conceptual understanding. Alongside this knowledge have come a…

This thesis explores impact of evidence-based active-engagement courses (EBAE) on student achievement and gender gap in introductory physics. The first study is about the pedagogical content knowledge (PCK) of the physics teaching assistants (TAs) at identifying introductory students' difficulties using the Conceptual Survey of Electricity and…

The purpose of this descriptive case study was to describe elementary level school teachers' experiences who worked with English Learners in a project-based learning model of instruction. The study focused on how teachers developed, planned, or utilized curriculum to support the language acquisition of their English Learners to meet state and…

The purpose of this study was to examine the impact of teacher education and professional development on teachers' perceptions of efficacy with providing effective English language instructional support to English learners. Using Bandura's (1997) self-efficacy theory, this study also analyzed the relationship between perceptions of efficacy and…

Currently, the majority of students with disabilities are educated in a general education classroom, which led to a paradigm shift and pedagogies used to meet the needs of all students. The research problem was that general education teachers use of highly effective evidence-based interventions that improve academic achievement for students with…
