This is the first of seven modules designed to help teachers gain the knowledge and skills needed for successful team teaching. The user may choose one, several or all of the modules, in any sequence, with module 1 recommended as a prerequisite to all the others, and module 5 as a prerequisite to module 6. The pattern of each module is: 1) study guide, with a series of questions and an interpreting key to decide on a specific course of study of the remaining materials; 2) a group of multi-media learning activities which the user studies according to the results of the study guide questions; 3) questions following each learning activity to enable the user to check his recall of information; and 4) module posttest which gives the user the opportunity to demonstrate his recall and integrate information for a complete understanding of team teaching. The user's manual on the modules and the outlines of the content are repeated at the beginning of each module. The study material in module 1 includes a review of selected literature; two articles: "Teaching in the Big Room," and "Team Teaching, Team Learning, Coordinate and Collaborative Teaching"; a viewing guide for the film "Team Teaching on the Elementary Level"; a guide for the tape "General Background of Organizational Changes in the School"; and mastery quizzes for the study materials.
