Project Adventure, an innovative educational program combining experiential learning in academics with a rigorous physical education curriculum at the high school level, was successful in its first year (1971-72). Project staff attempted to: develop and teach the physical education component; involve students and faculty in experiential dimensions of the existing science and social science curriculum; and develop student self-confidence. Six quantitative pre- and post-tests were given to the 224 participating high school sophomores (120 males, 104 females). Both boys and girls significantly improved their performance on virtually all physical education tests and generally increased their self-concept. Girls showed significant gains in self-concept. Contrary to expectations, no group significantly changed their perceptions of their physical selves. Also unexpectedly, girls in the program performed as well as boys despite the outdoor orientation and emphasis on materials usually associated with boys. At the end of the year participating students reported greater self-confidence (especially due to the physical education component), perception of less external control, and more activity both in and out of class. Recommendations included continuation of the program and periodic evaluation. The cover sheet notes availability of Project Adventure materials. (SB)
