Preparing Mentors to Support Novices in Eliciting Student Thinking in Mathematics Discussions



TeachSIM is partnering with researchers at Boston University and the University of Michigan to design online, portable mentor teacher professional development (PD) materials, including simulations and coaching supports, that target mentors’ teaching and feedback skills in elementary mathematics.


This work is essential for many reasons, including the following:


  • Mentor teachers (termed mentors), provide the most immediate and enduring influence on how candidates teach (Smagorinsky et al., 2006). However, elementary classrooms continue to be dominated by teacher-centered exchanges in which students provide brief, immediately assessed responses (Cohen, 2015, 2018; Kane & Staiger, 2012) that fail to position students as sense-makers (Kazemi & Stipek, 2009).
  • Robust professional development (PD) opportunities for mentors are scarce (Feiman-Nemser et al., 1993; Grossman, Ronfeldt, & Cohen, 2011). In order to model the ambitious teaching practices advocated in mathematics education research and to provide actionable feedback to candidates on such practices, mentors likely need PD as both teacher learners and as teacher educators (Matsko et al., 2020).
  • Several recent studies suggest that an effective mentor during student teaching can greatly accelerate candidate development, leading to more instructionally effective early career teachers (Goldhaber et al., 2018; Matsko et al., 2018; Ronfeldt, Brockman, et al., 2018; Ronfeldt, Goldhaber, et al., 2018; Ronfeldt, Matsko, et al., 2020), who are far more likely to teach historically marginalized and minoritized youth.

Using a randomized control trial with mentor-candidate pairs, we will investigate the causal impact of the PD materials on both mentors’ teaching and feedback skills, as well as candidate’s teaching skills. We will also observe the mentors’ uptake and transfer of the practices from the PD materials, to the simulations, to live classrooms and mentoring conversations.


Development of the mentor PD materials and assessments will occur throughout the 2022-2023 academic year.
