EXPERIENCES INFLUENCING THE DEVELOPMENT OF REFORMED TEACHING BELIEFS AMONG FUTURE GEOSCIENCE PROFESSORS
This longitudinal research follows a broad population of geoscience graduate students and post-docs over a 12 to 18 month period to evaluate changes in teaching beliefs and to determine the significance of experiences such as participation in teaching-related professional development or serving as a teaching assistant. The Beliefs about Reformed Teaching and Learning (BARSTL) survey was administered to 609 geoscience graduate students and post-docs from various institutions across the US in year one. In year two, the BARSTL was re-administered to 308 of prior participants (51% of original population). The BARSTL is a 32-item Likert-type questionnaire designed to determine how aligned an instructor’s pedagogical beliefs are to reformed-based teaching of science. In addition, ten percent of the initial population (n=60) were interviewed during year one using the Teacher Belief Interview (TBI), a semi-structured interview with coding maps designed to capture the epistemological beliefs of teachers. Half (31) of these participants were re-interviewed in year two (52% of original population). The TBI allows for in-depth exploration of participants’ teaching beliefs.
BARSTL results show that participation in any professional development related to teaching beyond a short, required teaching assistant orientation has a statistically significant (p=0.01) impact on participants’ teaching beliefs. Participants who took part in semester-long professional development experienced a statistically significant shift in TBI score toward more reformed beliefs (p=0.02). We will present the findings of this study to suggest how we can best prepare our graduate students and post-docs for success in future careers.
