This manual was prepared for school administrators and staff in Illinois school districts. Following a statement of the rationale for preparing the manual, a section on discriminatory legislation discusses Title IX of the Education Amendments of 1972 and Public Law 19-597 of Illinois. The next section discusses sex role stereotyping in classroom activities and in textbook prose and illustrations. The next section gives examples of sexist and nonsexist use of language. "Balance vs. Imbalance" suggests how to examine instructional materials in math and science and in history and social science for portrayals of equality and inequality of the sexes. The following section presents five questions to ask in analyzing the content of an entire text. A summary gives guidelines for valid portrayal of the sexes. The conclusion suggests steps school administrators can take to help correct problems of sexist treatment and lists ways teachers can "neutralize" sexist materials in the classroom. A bibliography and list of resource organizations are included. (LMS)
