Preparing Biology Graduate Teaching Assistants for Their Roles as Instructors: An Assessment of Institutional Approaches

The inconsistency of professional development (PD) in teaching for graduate teaching assistants (GTAs) is a widespread problem in higher education. Although GTAs serve an important role in retention of undergraduate science majors and in promotion of scientific literacy in nonmajors, they often lack preparation and ongoing support for teaching. Given the recent national focus on instructional quality in introductory courses, our goal was to use an online survey to identify current practices of teaching PD for biology GTAs and compare these results with the last national survey on this topic. In responses from 71 participant institutions, 96% reported some mandatory teaching preparation for biology GTAs; however, 52% of these programs required 10 or fewer hours per year. Respondents wanted to change their programs to include more pedagogical information and teaching observations with feedback to their GTAs. Programmatic self-ratings of satisfaction with GTA PD were positively correlated with the number of topics discussed during PD. Although more schools are requiring GTA PD for teaching compared with the last national survey, the lack of program breadth at many schools warrants a national conversation with regard to recent calls for improving undergraduate instruction.     

A qualitative investigation of a mindfulness-based yoga program for educators: How program attendance relates to outcomes

Contemplative professional development interventions seek to help educators manage stress and improve emotion regulation, yet the mechanisms of action revealing how they result in positive psychological and physical outcomes remain unclear. Using focus groups based on levels of attendance, this qualitative study examined how educators with different levels of attendance perceived their experiences in Community Approach to Learning Mindfully (CALM), a mindfulness-based yoga program. Using theory-driven and data-driven codes, two researchers adopted a thematic analytical approach to independently code interviews. Results suggest that individuals across all groups indicated participation in CALM stimulated awareness of some kind—somatic, emotional, or awareness of thought patterns. However, participants who attended more frequently were more likely to practice mindfulness informally during routine activities. This increased skill integration was associated with improved outcomes. Program acceptability was high across attendance groups although those with low attendance felt stressed making time to attend the program. Collegiality emerged as an important benefit and catalyst for reinforcing practices. Implications for professional development are discussed, including the role of collegiality and the importance of program readiness.     

Student use of out-of-class study groups in an introductory undergraduate biology course

Self-formed out-of-class study groups may benefit student learning; however, few researchers have quantified the relationship between study group use and achievement or described changes in study group usage patterns over a semester. We related study group use to performance on content exams, explored patterns of study group use, and qualitatively described student perceptions of study groups. A pre- and posttest were used to measure student content knowledge. Internet-based surveys were used to collect quantitative data on exam performance and qualitative data on study group usage trends and student perceptions of study groups. No relationship was found between gains in content knowledge and study group use. Students who participated in study groups did, however, believe they were beneficial. Four patterns of study group use were identified: students either always (14%) or never (55%) used study groups, tried but quit using them (22%), or utilized study groups only late in the semester (9%). Thematic analysis revealed preconceptions and in-class experiences influence student decisions to utilize study groups. We conclude that students require guidance in the successful use of study groups. Instructors can help students maximize study group success by making students aware of potential group composition problems, helping students choose group members who are compatible, and providing students materials on which to focus their study efforts.
