This booklet outlines guidelines for choosing a teaching technique and describes a wide variety of techniques. It is intended as an aid to teachers of all subject matters. The first chapter develops a number of principles for choosing a teaching technique appropriate to a given situation, and divides techniques into three categories: 1) real-life, 2) simulations, and 3) abstractions from reality. The three subsequent chapters contain brief, concise descriptions of 10-12 techniques in each of these categories. Examples are 1) "real-life"--paid work experience, family membership, club activities, field trips; 2) "simulations"--role playing, games, inquiry training, laboratory experiments, in-basket, discussion; 3) "abstractions from reality"--lecture, recitation, programed instruction, computer assisted instruction, drill, examinations.
