Laser Pointers: Low-cost, Low-tech Innovative, Interactive Instruction Tool Original Research Article

This paper discusses the use of laser pointers at the Engineering and Physical Sciences Library, University of Maryland, College Park, as a personal response system (PRS) tool to encourage student engagement in and interactivity with one-shot, lecture-based information literacy sessions. Unlike more sophisticated personal response systems like clickers, laser pointers are low-cost and low-tech, but comparable in increasing student engagement.
