The District of Columbia Public Schools Nature Computer Camp (NCC) is an environmental/computer program which has been operating in the Catoctin Mountain Park (Maryland) since 1983. The camp operates for five one-week sessions serving a total of 406 regular sixth-grade students representing 84 elementary schools with an average of 81 students per session. NCC is designed to: reduce geographical isolation of urban youngsters; provide opportunities to live and learn through contact with nature; develop computer literacy; and improve the children's social and interpersonal skills. Findings of this evaluation study are as follows: (1) all aspects of the program were given a high rating by a majority of students; (2) results of the student attitude surveys on 406 students showed that student campers maintained or increased positive views toward the program; (3) postassessment scores on counselor checklists showed that campers acquired appropriate socialization; and (4) students demonstrated mastery in measurement and problem solving skills. Results on a sample of 240 cases for which both pre- and posttest science and computer scores were available revealed significant increases in both areas. A recommendation and seven appendixes which include forms, records of student participation, checklists, and student attitude surveys and rating scales complete the document. (LL)
