An overview of six major issues in computer ethics is provided in this paper: (1) unauthorized and illegal database entry, surveillance and monitoring, and privacy issues; (2) piracy and intellectual property theft; (3) equity and equal access; (4) philosophical implications of artificial intelligence and computer rights; (5) social consequences of robotics and the automated office, human skill obsolescence, and job displacement; and (6) computers as tools of war. Materials and activities which are appropriate for teaching computer ethics at the middle or high school level are described, including readings, arguable premises, movies, case studies, the Eliza software program, data exercises, guidelines/policies, debates, conferences, and content analysis exercises. Two of these strategies--the arguable premise and the case method--are expanded upon for the high school setting, and ways in which computer ethics might fit into the curriculum are discussed. The agenda of a new organization, the Center for Applied Ethics and New Technologies, which provides curricular material on computing technology ethical topics, is also introduced. Seven case studies for classroom use are appended. (MES)
