How do I select which Purdue-supported student response system I should use (Hotseat or iClickers)?

Overview

Purdue supports two student response systems. These are used within a class to solicit student questions, answers, etc. The instructor can then use this information to determine student understanding, lead discussions, etc. For more general information on how to use iClickers, click here.
