Investigating The Relationship Between Departmental Support Structures, Self-Efficacy And Intention To Persist: An Examination Of Students' Experience In 19 Physics Graduate Programs Across The United States, Diana Sachmpazidi
Dissertations
Science, Technology, Engineering, and Mathematics (STEM) graduate programs experience consistently high attrition rates. Moreover, persistent disparities exist in racial and gender representation. Women and People of Color are significantly underrepresented and have higher attrition rates than men and white and Asian American students. To date, little work is done to understand graduate student attrition or persistence. There is also a lack of information regarding the causes of demographic disparities in attrition. Most past studies in this context have focused on students' attributes, undergraduate preparation, and mentoring relationships. Moreover, student self-efficacy is a contributing factor for undergraduate student retention. Yet, there …

Instructional Change In Academic Departments: An Analysis From The Perspective Of Two Environment-Focused Change Strategies, Kathleen M. Quardokus
Dissertations
Numerous reports demand changes in college and university teaching practices. This is especially true for science, technology, engineering and mathematics (STEM) disciplines. STEM stakeholders are concerned about student retention within STEM majors, as well as the lack of sufficient graduates with the knowledge to advance these fields. A common conclusion of these reports is that teaching practices must change. Although these calls for change have occurred for decades, STEM fields have yet to experience widespread change. Thus, there is a need for more effective change strategies. Recently, researchers have suggested that effective change strategies should focus on changing the environments …
Chemistry Graduate Teaching Assistants: A Comparison Of The Classroom Discourse Within Expository And Problem-Based Learning Laboratories, Kelley M. Current
Chemistry Graduate Teaching Assistants: A Comparison Of The Classroom Discourse Within Expository And Problem-Based Learning Laboratories, Kelley M. Current
Masters Theses
Graduate Teaching Assistants (GTAs) commonly function as instructors within undergraduate chemistry laboratories. This study sought to explore and describe GTA classroom discourse within two distinct instructional modes, using discourse analysis as the theoretical framework. Theclassroom discourse within a series of verification style labs was comparedto the classroom discourse produced within a set of Problem-Based Learning (PBL) labs. The results suggest three primary findings: (1) the apparent relationship between the instructional mode and form of GTA classroom discourse, (2) the patterns in classroom discourse observed within a given instructional mode repeat, irrespective of content, and (3) the classroom discourse observed within …
