This guide, one of a series designed to aid the social studies teacher, discusses the importance of a class study, offers suggestions for collecting information, a convenient form for recording the data, and suggestions for its analysis and use. The class study plan is presented in two parts: a study and composite picture of individuals of the class, and a study of the class as a group. The information provides analysis of the class as individuals for diagnostic purposes, as well as an understanding of the dynamics of the group's interaction. The composite picture includes general data on each individual, his academic competence, personal perceptions, and extra-school factors. The class as a group is examined for its structure, satisfaction of needs, group perceptions and behavior, and general class atmosphere. Utilization of the class study includes spotting future problems, meeting existing problems, pupil teacher planning, and evaluating the class and the teacher. A copy of the form is included.
