Student response systems enable an instructor to pose a question or problem and have students respond. The instructor’s computer analyzes the responses and displays a summary. Some of the systems use a clicker, a device that resembles a TV remote control, and most of them integrate with – but do not require – PowerPoint.
At Notre Dame, we encourage faculty to use the online service Poll Everywhere, which allows students to respond with a cell phone or laptop instead of a clicker.
Potential instructional benefits include the ability to gauge student comprehension, to encourage class participation, and to keep students engaged. The instructor can pose impromptu questions or conduct an opinion survey. Questions posed with Poll Everywhere can be embedded into a web page.
