Talk moves simulations were used in tutorials for a mathematics education unit. Pre-service teachers (PSTs) and tutors were surveyed about their perceptions of the purposes, benefits, and drawbacks of the simulations. There was strong support from both groups for the benefits of talk moves in developing PSTs' ability to manage discussions, ask good questions, and understand students' thinking. Tutors were more inclined than PSTs to note improvements to PSTs' mathematical knowledge. Challenges to implementation were authentic engagement in the simulations, PSTs' lack of experience with children, the cognitive load associated with managing discussions, and limited mathematical knowledge.
