Developing electronic classroom response apps for a wide variety of mobile devices. Insights into the PINGO project
1. The document discusses the PINGO project, which aims to develop electronic classroom response apps for a wide variety of mobile devices using a web-based approach. 2. It outlines challenges with using peer instruction in very large groups and how PINGO addresses issues like high costs, device compatibility, and scalability through a free web-based platform. 3. The platform allows instructors to push questions to students' mobile devices and sync response timers between the backend and devices to support peer instruction for groups of 5000 students or more.
