This study was conducted to compare upper elementary school children's attitudes toward physical activity, by grade level and gender across six attitude scale subdomains in order to assist physical education teachers in planning programs designed to foster positive attitudes toward physical activity. Subjects (N=429) were 243 girls and 186 boys in grades 3 though 6, from 11 elementary schools and 35 classrooms. The Children's Attitude Toward Physical Activity (CAPTA) inventory was utilized to assess attitudes across six subdomains: (1) social; (2) health and fitness; (3) vertigo; (4) aesthetic; (5) catharsis; and (6) ascetic. Findings indicate that: upper elementary school children's attitudes toward physical activity are best described by interaction of gender and specific attitude subdomains; androgynous programming in elementary physical education reduces gender differences, thereby expanding opportunities for both genders; and younger children's attitudes toward physical activity can be shaped more positively through androgynous socialization into physical activity. A list of references, an analysis of variance summary table, and four figures complete the document. (LL)
