This workbook is designed to provide beginning and experienced teachers and administrators with a guide to evaluating and selecting materials with respect to the student who uses them, the instructor who teaches from them, and the program that orders them. It is intended to be either self-instructive or used in conjunction with a staff development workshop. Modules 1-4 consider the participants--the student and the teacher. Topics are forces that affect the returning adult students, teaching styles, assessment of teacher areas of expertise, and learning styles. Modules 5-11 discuss the text itself, including textbook organization; orientation of material; the roles of diagnosis, reinforcement, evaluation, and assessment; adult tone; format and appearance; readability formulas; and teacher development of supplemental lessons. Module 12 discusses the design of the program and how it affects the texts that are used in a class. Components of each module may include some or all of the following: an objective, introduction, informative material, examples, activities, suggestions for the reader, and a list of references. A simulation game, a suggested outline for a materials evaluation workshop, and a materials evaluation checklist are appended. (YLB)
