The basic goals of Peer Instruction are to encourage and make use of student interaction during lectures, while focusing students' attention on underlying concepts and techniques. The method has been assessed in many studies using standardized, diagnostic tests and shown to be considerably more effective than the conventional lecture approach to teaching. Peer Instruction is now used in a wide range of science and math courses at the college and secondary level. In this 90-minute workshop, participants will learn about Peer Instruction, serve as the "class" in which Peer Instruction is demonstrated, discuss several models for implementing the technique into the classroom, and learn about available teaching resources.
