When directing a class discussion, teachers must consider many factors: Who speaks? For how long? And what type of questions are they asked? In this tech demo, participants will experience a simulation called Managing Whole Class Discussions designed to give teachers the opportunity to manage a whole class discussion. We will then reflect and discuss in-simulation actions using the EQUIP tool (Reinholz and Shah, 2018), an analytic framework for “quantifying” equity in a class discussion to promote teacher reflection. Participants will also look at data visualizations of simulated data to give feedback for future design iterations.
