This guide is one part of eight instructional units developed by the Human Behavior Curriculum Project. These units provide a systematic study of behavior which can increase understanding of everyday life. They can be used to supplement other courses or as a separate course of study. There are three themes common to the units: (1) Human behavior can be observed, but it is necessary to teach strategies for careful objective observation of behavior; (2) There is enough regularity in human thought and behavior so that it is possible to arrive at general statements about patterns and causes of psychological events; and (3) In addition to our similarities, it is essential to preserve the sense of human individuality. The units were prepared by teams of high school teachers, students, and specialists in the field of human behavior. All materials were designed to involve the student actively in the learning experience. The teacher's handbook contains supplemental resources, including a bibliography and suggested films, nine lessons, and handouts for class activities. (Author)
