This 1976 review by the Michigan Department of Education of senior high school government textbooks used in Michigan schools suggests that the majority of textbooks are "grossly lacking" in terms of the fair inclusion of the "achievements and accomplishments of ethnic and racial groups," as specified in Act 127 (Social Studies Textbook Act) of the Public Acts of 1966. To determine the acceptability of 12 recently published and widely used government textbooks, 18 Michigan educators were selected to write two reviews each (36 reviews total). The books were noted on a five-point scale from excellent to very poor. Of the 12 books rated, 17 percent were rated excellent; 19 percent were rated good; 28 percent were rated fair; 36 percent were rated poor, and no books were rated very poor. Chapter titles of the study include (1) Introduction; (2) Government-Related Courses in American Education: A Historical Review; (3) Government-Related Courses in Michigan Schools; (4) Design of the 1976 Social Studies Textbook Study; (5) Results and Discussion; and (6) The Government Textbook Reviews. Appendices are included. (Author/DB)
