Training Teaching Assistants by Offering an Introductory Course

ABSTRACTTeaching assistants (TAs) are often used in computer science (CS) courses to conduct tutorials in smaller groups and to be able to provide students with one-to-one help sessions. TAs can also assist with the assessment, which can be time-consuming in large classes. Previous research does, however, indicate that TAs can be poorly prepared for their work tasks. In this experience report, we present a TA training course that addresses this issue and prepares new TAs for their responsibilities. This includes conducting tutorials, tutoring and providing students with useful feedback in lab settings, and conducting assessments. In addition, we also aimed at creating a safe space for our TAs to discuss challenges and fears that they foresee or have already experienced as TAs. To do this, we developed an introductory course consisting of five modules, that are based on previous research on TAs in CS and in the Technological Pedagogical Content Knowledge (TPACK) framework. The modules are: HR questions, classroom teaching, helping and supervising in lab sessions, assessment, and reflection and discussion. The course is given in a blended learning format, where the first three modules are student-paced online modules, while the last two are synchronous meetings. To evaluate the training, we present course evaluation results from 53 TAs who enrolled in this 6-hours course during the 2020/2021 academic year. We conclude that this TA training course has been well appreciated by almost all the participants, discuss lessons learned and future plans.
