This paper describes a three-year project funded by Title IV/C of the Elementary and Secondary Education Act (ESEA) and initiated by the Minnesota state board of education to reduce sex bias among students and teachers in Minneapolis. Emphasis during the first year of the project was on the development of nonsexist curriculum materials to be used in intermediate and secondary classrooms. During the second year, lessons were developed for use in primary classrooms. The third year focused on the extent of attitude change. By the end of the project, 95 percent of Minneapolis teachers had received inservice training in nonsexism with the understanding they would teach the nonsexist lessons in their classrooms. Data were collected via questionnaires, interviews, and observations. Results showed that the use of nonsexist curriculum materials changed student and teacher attitudes to a significant degree. With the exception of the secondary level, teachers reported they and their students became more aware of the need to focus on the elimination of sex bias from the educational system. The report hypothesized that because students continually change classes at the secondary level, there is less chance for any single teacher to serve as a role model. Also, nonsexist lessons being taught become much more diffused when they are only a part of a one-hour class. (Author/LD)
