Peer Mentor Program

The Peer Mentor Program helps graduate students in mathematics transition from Graduate Teaching Assistant (GTA) to Graduate Student Instructor (GSI) through teaching observation and small group discussions.


During a mathematics graduate student’s development at UofSC, graduate students transition from Graduate Teaching Assistant (GTA, e.g. recitation instructor) to Graduate Student Instructor (GSI, e.g. full instructor of record). This transition is supported through mathematics graduate student orientation, observations, the two pedagogy courses (Math 791 and Math 792), and the peer mentor program. Initially funded by the National Science Foundation (NSF Awards #1544346 & #1725295), the peer mentor program provides two critical foundations for support: teaching observations and small-group discussions around teaching. Experienced graduate students are trained as mentors to facilitate productive and open discussions about the challenges facing teaching and provide post-observation feedback to first year (novice) GSIs. These two levels of support have been beneficial to the UofSC mathematics department culture of graduate student teaching as well as undergraduate student learning (Yee & Rogers, 2016; Yee & Rogers, 2017a, 2017b, 2017c; Rogers & Yee, 2018).

The following logic model demonstrates the layers of support from GTAs to GSIs at UofSC:

Parts of Peer Mentor Program

Included in the development of the peer mentor program are:

  • A full semester-long professional development to teach mentors how to facilitate meetings and observations with novices.
  • The Graduate Student Instructor Observation Protocol (GSIOP, Yee et al., 2019) designed for GSIs teaching service mathematics courses emphasizing student engagement.
  • Post-Observation Feedback Structure (Red-Yellow-Green Feedback, Yee et al., 2019) where mentors give supportive and nurturing feedback on how to improve.
  • Small group meeting topics of value to novice GSIs including, but not limited to: collaborative learning, student engagement, critical reflection, managing constructive criticism, formative and summative assessment, grading, classroom management, creating/modifying lesson plans, time management, specific content advice.
