This master's thesis investigates the effects of exposing children to curriculum materials that show men and women can do the same work. Four classes of second graders served as subjects. All subjects were pretested on an occupational classification measure. Two of the participating classes were randomly selected to receive the experimental curriculum treatment. The experimental materials, consisting of a six-week social studies unit, represented male and female workers performing the same jobs in a Chinese commune. One class received a placebo treatment consisting of materials dealing with the children's own community and representing male and female workers doing different jobs. The fourth class served as a combarison group. Between pretests and posttests the number of jobs which subjects said could be done by both sexes increased significantly for one of the two experimental classes and for the placebo class. Children's responses on a subset of six jobs done by both male and female workers from the occupational classification measure were studied separately. Between the pretests and the posttests the number of subset jobs which subjects said could be done by both sexes increased significantly for both experimental classes and the placebo class. It was concluded that curriculum materials can be used to expand the number of jobs children classify as suitable for both sexes. (Author/RH)
