In order to equip teachers for the complexity of their job, teacher education programs have shifted away from training teachers in exactly what to do, focusing instead on how to approach the classroom. Teacher educators are working towards programs that develop beliefs that directly and positively affect the actions of teachers in the classrooms (Darling-Hammond, 2006). One particularly interesting case of teachers-in-training are graduate teaching assistants (GTAs), because they are both students and teachers simultaneously. In addition, GTAs are often learning how to teach while organizing, managing, and instructing classes, with varying levels of experience, training, responsibility, and support (Jordan & Howe, 2018; Patel, 2017). Although there is a body of work exploring the roles GTAs play as students and in institutions (Jordan & Howe, 2018; Park, 2004), GTAs have not generally been examined as classroom teachers. This study explores language GTAs’ beliefs about teaching, how their beliefs connect to their practice, and factors that affect their ability to implement their beliefs using data collected through semi-structured interviews and classroom observations. The findings show that GTAs (1) describe, instead of state, their beliefs focusing on classroom atmosphere and communicative language teaching factors; (2) are able to demonstrate their beliefs at least some of the time in their teaching; and (3) report contextual factors, such as time constraints and departmental training, that both hinder and facilitate their ability to implement their beliefs in their practices. Based on these findings, it is suggested that GTAs be provided opportunities to explicitly identify and reflect on their beliefs, make clear and accurate connections between their teaching and their beliefs, and experience an appropriate balance of support and autonomy. These suggestions are made so that GTAs might be more successful in integrating their beliefs and practices in ways that allow them to fulfill their roles as students and teachers well.

Through an exploratory qualitative, interpretive frame that employed an ethnographic methodological approach, this research focuses on teaching assistants (TAs) teaching in a lab, tutorial, or discussion group. Nine TAs share their learning journey as they begin teaching in higher education. The theoretical lens that frames this research is workplace learning. Interviews, observations, video-recordings, field notes, and learning diaries were subjected to thematic analysis, looking for dominant themes associated to TAs’ characteristics, their learning process related to teaching, and the knowledge they developed about teaching and student learning. Key findings include the recognition that TAs bring robust conceptions and dispositions to their first teaching position that is approached from a student subject position as they are becoming teachers. As TAs are being teachers, they control their self-directed learning process as they make decisions on-the-fly within a diverse learning environment that ranges from expansive to strategic to restrictive affordances. Coupled with a discretionary reflective practice, TAs’ knowledge development about teaching and student learning is solely dependent upon their experience, making forthcoming development of knowledge about teaching and student learning relegated to chance. This focus on TAs’ learning in the workplace illuminates the need for a deep learning approach to learning about teaching and student learning that needs to begin with graduate students’ first appointment as a TA. In addition, this deep learning approach needs to be encased in an expansive learning environment that provides opportunities for continuous support through various forms of mentorship, instruction, and development of reflective practice. / Graduate
