Recent evidence suggests a mental health crisis among graduate students, particularly with regard to anxiety. To manage anxieties, graduate students can employ coping strategies. Coping is an individual's response(s) to external stressors, often with the goal of reducing or tolerating the stress; these strategies are generally considered adaptive…

Biology graduate teaching assistants (GTAs) are significant contributors to the educational mission of universities, particularly in introductory courses, yet there is a lack of empirical data on how to best prepare them for their teaching roles. This essay proposes a conceptual framework for biology GTA teaching professional development (TPD)…

Graduate teaching assistants (GTAs) are often used as instructors in undergraduate introductory science courses, particularly in laboratory and discussion sections associated with large lectures. These GTAs are often novice teachers with little opportunity to develop their teaching skills through formal professional development. Focused…

Science education reform documents identify nature of science (NOS) as a critical component of scientific literacy and call for universities, colleges, and K-12 schools to explicitly integrate NOS learning into science curricula. In response to these calls, this study investigated the classroom practices of nine graduate assistants (GAs) who…

Graduate teaching assistants (GTAs) are used extensively as instructors in higher education, yet their status and authority as teachers may be unclear to undergraduates, to administrators, and even to the GTAs themselves. This study explored undergraduate perception of classroom instruction by GTAs and professors to identify factors unique to each…

Undergraduates often use single words to describe their instructors, including "boring," "enthusiastic," and "organized," but what instructional behaviors cause students to use these words? This study utilized interviews and an online survey to ask students to translate commonly used instructor descriptions into their…

Undergraduate experiences in lower-division science courses are important factors in student retention in science majors. These courses often include a lecture taught by faculty, supplemented by smaller sections, such as discussions and laboratories, taught by graduate teaching assistants (GTAs). Given that portions of these courses are taught by…

This study assessed student attitude towards reformed laboratories featuring a factorial design of inquiry (IN) and explicit/reflective (ER) pedagogy to foster nature of science understanding. Students in thirty-one lab sections responded to pre and post semester assessments of their confidence, perception of usefulness, and effectance motivation…

Students need to reflect on the practice of science to fully understand the nature of science (NOS), which is an important component of scientific literacy. In this paper, the authors describe how to implement an explicit and reflective pedagogy in college science laboratories and share examples from their implementation in a multiple-section…
