Abstract

Cognitive and affective beliefs in physics classrooms are important indicators of student success beyond traditional measurements of academic performance. This body of work explores major beliefs and processes, including self-efficacy, self-regulation, and sense of belonging, as they relate to academic achievement among introductory undergraduate physics students. First, this dissertation explores the development of physics self-efficacy and physics sense of belonging, two highly correlated variables. This work identifies unique sources of physics self-efficacy and sense of belonging development from current and prior academic experiences, personality factors, and demographic variables. Then, relationships between early- semester self-efficacy and sense of belonging, mid-semester self-efficacy and sense of belonging, and influences from academic performance feedback are explored. Physics self-efficacy and sense of belonging are then observed to evolve over multiple introductory physics courses, identifying patterns over time, between demographic groups, and by academic achievement. The next part of this work applies the concept of self-regulated learning to introductory physics students. First, student learning strategies were tracked over a semester to explore how strategy use evolved over time and responded to academic feedback. Then, an instrument was designed and validated to measure self-regulated learning behaviors relevant to learning physics and used to identify behaviors that set high-achieving students apart from lower-achieving students. The last study in this body of work expands the principles of physics education research to mathematics education research, exploring differences in mathematics performance/competence, interest in mathematics, interest in mathematics graduate school, and perceived barriers to pursuing mathematics graduate education.
