I just came across a new book on using classroom response systems, AKA clickers.
Bruff, D. (2009). Teaching with Classroom Response Systems: Creating Active Learning Environments. Jossey-Bass, San Francisco, CA.
Bruff provides suggestions for how to use clickers to engage students in learning, including peer teaching, group learning, and gathering information about student understanding. He provides examples from a variety of disciplines ranging from physics to language instruction. There’s also practical advice on structuring class time, preparing questions, and using clickers for grading.
Finally, Bruff discusses technical and logistic issues, providing practical suggestions on getting started with low tech alternatives to clickers.
