The increasing availability and the highly variable quality of computer hardware and software make it imperative that school professionals become acquainted with issues of legal liability and professional ethics regarding the use of computers in education. This document explores problems associated with the lack of proper training of school professionals and suggests ways to minimize the potential for such problems. The document begins by defining liability, its three basic categories (nonfeasance, misfeasance, and malfeasance), and seven points of law that apply to personal injury or complaint liabilities. The document then lists (1) eight environmental influences on public and private educational policymaking that are hampering the adequate and appropriate use of computers in education and (2) six misdirected uses of computers in the classroom. Next, the document considers nine general areas (case topics) of legal liability, gives examples of the kinds of computer misuse that could fall under each category, and shows how schools might be held liable for certain transgressions. The document then provides an 18-point checklist of activities for teachers and administrators to use in avoiding liability problems and concludes by arguing for more adequate and appropriate teacher and administrator training.
