Replicating a study conducted 10 years earlier in Colorado, a research project documented current gender perceptions of Wisconsin students and compared responses to those reported in the earlier study. The Wisconsin study included 3,363 students in grades 4, 6, 8, 10, and 12 in 26 schools who were asked the question, "If you woke up tomorrow and discovered you were the opposite sex, how do you think your life would be different?" Findings indicated that almost all girls and boys at all grade levels were satisfied with their gender. However, both girls and boys thought boys' lives were easier and more fun, whereas girls needed to be more reasonable and serious. From about the sixth grade on, there was no doubt that both boys and girls thought there was a difference in the quality of treatment by others and agreed that girls were not treated as well as boys. In the upper grades, girls said their parents would be more relaxed and not worry so much if they were boys. Surprisingly, few children mentioned differences in relationships with family members. There was almost no evidence that boys and girls agreed they were treated differently in the classroom. Both boys and girls agreed that the opportunity to be able to participate in sports, both on the playground and on school and community teams, was the major advantage of being male. At all grade levels males and females thought job opportunities were different and that males had more opportunities. (Data tables and instruments are appended.) (YLB)
