Chemistry ConcepTests: A Pathway to Interactive Classrooms is an introduction to an emerging peer-teaching technique for the effective teaching of introductory chemistry courses. The simple method of asking focused questions in lecture, then permitting students to vote, discuss, and vote again on the answer, has altered not just course mechanics but course culture. The peer instructional practices that it promotes can enliven a course for both students and instructors. This book introduces chemistry teachers to this technique and some of its many variations.
