Zastrow's book is a rich resource and hands-on guide that students like to keep for future reference. This ten-part book has each chapter module broken down into a particular format. First, the goal of the chapter is stated; then the chapter provides the theoretical material for the class; and then, exercises are given to illustrate the key concepts in the chapter. Students are encouraged to break into groups and lead the class in the exercises - the class then becomes a lab for students to learn how to work in and lead all kinds of groups.
