Improving Undergraduate STEM Education through Hospitableness, Justice, Status, and Identity Público
Hayward, Jennifer (Fall 2020)
Abstract
Despite the plethora of studies on STEM persistence and the disparities within STEM since the 1990s, uneven progress has been made in substantially increasing women and underrepresented groups across STEM disciplines. The time students spend in their post-secondary education critically influences their future development as people, employees, citizens of a nation, consumers, activists, and many other identities and roles. I explore STEM students’ experiences in the classroom, their perceptions of these experiences, as well as possible implications of their experiences on their persistence. Specifically, I focus on overlooked social psychological processes (see Xie, Fang, and Shauman 2015) unfolding in STEM classrooms as potential facilitators or inhibitors of continuation in such fields.
Broadly, my dissertation research investigates the influence of classroom dynamics on students’ experiences in the classroom. More specifically, in Chapter 1 I investigate the pedagogical practices and conditions that shape the classroom climate students experience as they take their classes. In Chapter 2, I explore how students’ experience of classroom dynamics through justice and status processes shape their emotions and perceptions of competence. Finally, in Chapter 3, I turn to students’ development and solidification of a science identity, and the effects of a science identity on persistence in STEM.
The dissertation consists of three empirical papers stemming from data collected through observations and surveys in fall 2017 and fall 2018. I draw on data gathered from 137 hours of classroom observations in introductory biology and computer science classes over the Fall 2017 semester at a private university in the Southeast to provide the basis for Chapter 1 addressing classroom climate. Chapters 2 and 3 take a quantitative approach to students’ experiences in the undergraduate STEM classroom relying on survey data collected from students (n=786) in biology and computer science over the course of two fall (2017, 2018) semesters. I use this survey data to examine how perceived classroom dynamics, assessed in terms of justice and status processes, affect emotional and cognitive responses (Chapter 2) and how those responses to the classroom facilitate or inhibit the development of science identities and persistence in STEM (Chapter 3).
