Working with a team of Graduate Student Instructors (GSIs) and/or Undergraduate Teaching/Learning Assistants (UTAs and ULAs) creates instructional opportunities in large courses that may not be possible otherwise. In this session, we will share examples of course teams from U-M and identify the benefits, challenges and best practices of building and working in these teams. Throughout our discussion, we will reflect on the process of developing a teaching team, roles and responsibilities for GSIs and UTAs, the training, interaction and support needed as the course is being taught, as well as mechanisms for feedback and evaluation. We will also explore the role of identity in relationships among faculty, GSIs, UTAs, and students.
