A study was conducted to review the summer experiences of industrial arts students who participated in Tennessee's Summer Youth Development Program at Camp Clements State Park and the affective behavior changes that took place as a result of the students' summer experience. The study used an ethnographic research design to examine the culture of the middle school industrial arts classroom before, during, and after the summer youth leadership development experience. The school selected was a Knoxville, Tennessee, middle school close to the researchers, with an industrial arts program having an aggregate of students from low to middle socioeconomic status and a racial mix representative of the geographic area. The researchers observed in the classroom before and after the summer camp experience, with particular attention to five factors: ambition; self-control; organization; enthusiasm; and conscientiousness. Three students were singled out for particular observation. Results of the study showed that the students who participated in the camp, although leaders before the summer, exhibited growth in all five factors. They took a more active role in the classroom and assumed responsibility without direction of the teacher. It was noted, however, that the behavior may also have been influenced by teacher expectations. (KC)
