D ESIGNING A WEB - BASED APPLICATION TO SUPPORT P EER I NSTRUCTION FOR VERY LARGE G ROUPS Research - in - Progress

In this research, we introduce a web-based open source solution that enables the transfer of the widely established Peer Instruction approach to lectures with in excess of 350 participants. The proposed solution avoids several existing technical flaws that currently hinder the further adoption of Peer Instruction. We test our solution in a series of lectures with over 500 participants. Within these tests, we evaluate our prototype using the Technology Acceptance Model, the System Usability Scale, as well as qualitative interviews. Both the evaluation results and the feedback from course participants indicate that our new solution is a useful artifact for implementing Peer Instruction in lectures with very large groups.
