A study examined gender stereotyping in an outdoor adventure education program. Observations, interviews, and document reviews involving 138 adolescent students from 8 schools attending a residential outdoor education center in Queensland (Australia) found the following gender stereotypes: boys are physically stronger than girls; boys are practical and do things whereas girls plan ahead; boys are clowns; girls are bossier than boys; boys are more competitive than girls; and girls have better relationship skills than boys. Gender stereotyping provided structure and order that gave a sense of safety and familiarity to many participants. It also regulated behavior, placed limits on perceived abilities, and accorded different situational statuses to girls and boys. It was predominantly boys who were accorded the highest status, based upon their perceived greater physical strength and the way they claimed leadership and power. It was more difficult for girls' voices to be heard within this structure. Stereotyping worked through the assertion of power and control. Different types and levels of power were observed. The most obvious form was seen in who set the "tone" of the group, usually a boy or group of boys, who were loud, strong, and popular. Some boys asserted their power through physical strength and by taking the lead on the trail. Some girls asserted their power through group maintenance tasks. Some girls and boys demonstrated their empowerment through resistance of gender-stereotyped roles. Implications for practice are discussed. (TD)
