This article describes the outcomes of using a scaffolded set of two digital, simulation-based approaches to support secondary mathematics and science preservice teachers (PSTs) in learning to facilitate argumentation-focused discussions. The researchers investigated PST and teacher educator (TE) impressions of the experience and collected…

In this study, three math and three science teacher educators (TEs) were positioned as designers of instruction. The investigation considered how TEs supported preservice teachers (PSTs) to learn to facilitate argumentation discussions using two digital simulations. Research questions were (a) How did TEs engage in instructional design around the…

Preservice teachers (PSTs) need to be able to use ambitious teaching practices to help support their students' productive engagement in scientific practices such as analyzing and interpreting data or using evidence-based reasoning to support their claims. Approximations of practice are one way in which teacher educators can support their PSTs to…
