This research study examined inclusive teaching practices, class policies, and course structures in active learning Calculus classes. Analyzing interview data, along with focus group discussions and classroom observations, obtained from 23 students and 4 instructors, themes were extracted through open-coding methodology, employing scholarly…

Though statistical testing is commonly practiced, the logic of statistical tests is confusing, thinking about distributions is difficult, and the way statisticians formulate expectations as probability distributions is poorly understood. To support instruction, the statistics education community has increasingly utilized simulation-based…

COVID-19 exacerbated a pre-existing and well-documented mental health crisis on college campuses in the United States. During COVID-19, more college students than ever before in recorded history reported feelings of anxiety and depression, among other mental health issues. There are myriad possible causes for the decline in mental health among…

In this dissertation, I report results from a study that investigated the impact of students' engagement in a series of tasks in an introductory proof course that was designed to stimulate their learning of reading strategies to support their comprehension of mathematics proofs. Specifically, I investigated the impact of the design of five…

The purpose of this study was to examine how pre-service teachers (PSTs) develop their teaching adaptive competence through teaching rehearsal and repeated teaching, which is one of the focused teacher education strategies in practice-based teacher education (PBTE). This study was conducted in an introductory teaching methods course of a physical…

The focus of this dissertation is on students' thinking regarding the function concept in the context of abstract algebra, focusing on the properties of well- and everywhere-definedness. This dissertation follows a three-paper format, where each paper has a different yet related focus. In the first paper, I analyze (non-)examples found in…

Attracting and retaining diverse individuals is a core goal for reform efforts within in Science, Technology, Engineering, and Mathematics (STEM) gateway courses. Evidence-based instructional strategies in STEM, including those that incorporate scientific practices, have demonstrated promising findings regarding student learning gains. Inspired by…

Introductory calculus is mandatory for postsecondary science, technology, engineering, and mathematics (STEM) majors (Bressoud, 2015); however, many students do not persist through introductory calculus to further STEM study (Rasmussen et al., 2019). One reason for this may be that students struggle with the prior mathematical knowledge required…

Globally, the demand for people prepared to enter Science, Technology, Engineering and Math (STEM) careers is increasing. To help fill this demand, many formal and informal STEM educational interventions have been implemented in the K-12 domain. However, due to the lack of a clearly defined framework for documenting the nature and scope of the…

Many colleges and universities take a "weeding out the weak" approach to teaching STEM, despite substantial literature that emphasizes the values and effectiveness of various other approaches. Introductory, foundational, STEM courses which are often taken by students during their first and second years of college, have been shown to…

Large class sizes can be a barrier to seeking assistance, inhibiting student success. Efforts to improve student outcomes and address the reluctance of students to access academic resources lead many institutional leaders to turn to unique academic support initiatives, like supplemental instruction (SI). There is ample evidence that supplemental…

To realize more equitable technology futures, it is not enough to simply adapt technology to be more inclusive "after" it is created. We will also need to equip technology creators with the skills they need to critically reflect upon bias and exclusion "during" the technology design process. The question of how to best to…

There is a consistent concern for students' success in undergraduate introductory cell biology as this foundational course may impact their persistence towards earning a degree in the health sciences. Institutions need to consider the delivery method of instruction and the potential impacts on student success and enrollment. For five years, the…

Due to the life-altering effects reading ability has on one's life, the public, government, and educators have a vested interest in understanding how reading acquisition occurs and is most effectively taught. The body of research termed the 'science of reading' shows that at least 92 percent of children can read at grade level when given…

Touted as the future of language teaching, task-based pedagogy is grounded in current Second Language Acquisition (SLA) theories, and is in line with the trend of learner-centeredness in general education. However, the method has yet to be fully embraced by the language teaching community due to the lack of 1) clear delineation of pedagogical…
