This report presents a description and evaluation of the Nature-Computer Camp (NCC), an environmental and computer science program designed for sixth grade students in the District of Columbia public schools. Among the major components of the program were: planning for administration of operating the camp and for instruction in environmental science and computers; staff characteristics; staff development; record keeping procedures; scheduling; materials and supplies; academic curriculum (content and process); instructional process; and the socio-emotional curriculum (attitudes and skills). Observations of inputs for these program components revealed that the only problem encountered was lack of adequate materials and supplies. Overall, the implementation was completed with minimal problems. In addition, all program objectives were attained. These objectives included: a significant gain in knowledge in the areas of stream ecology, woodland ecology and geology, and in knowledge about computers; maintenance or an increase of a positive attitude toward the program; and demonstration of appropriate socialization using a set of social expectations established by staff and student campers. Supporting documentation (including evaluation model schema, data analysis summaries, camp schedules, and samples of expected social behaviors) is included in appendices. (JN)
