The District of Columbia's Nature Computer Camp program, described and evaluated in this paper, was designed to reduce the geographical isolation of economically disadvantaged urban sixth graders, and to provide them with increased knowledge of the environmental and computer sciences. The paper begins by giving details of the program's management, and of the curricula and instructional focus. Next, the program's success in meeting its main objectives is evaluated; it is concluded that the objectives were indeed met. That is, the camp was established and implemented as planned, and following participation in the week-long program, students demonstrated improved social skills and gains in knowledge in the areas of stream ecology, woodland ecology, geology, and computers. Furthermore, at least 80% of the participants maintained or increased a positive attitude toward the program. Eight appendices, which make up more than half of the document, include a schedule of camp events, a sample description of instructional modules, material on a camp scavenger hunt, a description of trails and activities, the evaluation model schema, a sample reporting form, evaluation questionnaires, and data summaries.
