A concern of the probable damaging effects of the treatment of women in high school textbooks on United States government led to this study of eight textbooks popularly used in senior high schools. A content analysis is reported along with recommendations for action and change. Chapters of analysis begin with a survey of where women are left out, noting index listings, quotations, illustrations, pictorial chapter openings, and terminology as examples of omissions. Next, methods by which women are put down are delineated, such as sex stereotyping in text, illustrations, and cartoons. Final focus is on subject matter important to women but usually ignored; examples include woman's role in voting, in political parties and elective office, and in relation to the judicial system and employment. Recommendations for building women up in new textbooks and for what to do until nonsexist textbooks are available are based on the conclusion that urgent revision is needed to incorporate attention to the role of women in political and governmental institutions. The final chapter contains an annotated source list of over 150 studies on sexism in textbooks and practical remedies. (Author/KSM)
