Using Wireless Keypads in Lecture Classes

Experience using a wireless keypad system for five years in class rooms is discussed. This system is designed to increase student participation. The data can be displayed to students quickly and/or saved. The system is flexible and can accommodate a wide variety of teaching styles.
