Within the framework of the Dutch national policy for the integration of computers in education, a cooperative research and development project is being carried out by two pilot schools (grades 7-12) and a team of researchers. Based on the results of an analysis of experiences and current practice on computer use in the two pilot schools and findings from research literature on teacher training, a plan for inservice training at the school-building level has been developed. The emphasis is on the training of teachers within the same subject area. This training consists of five steps: (1) orientation to and selection of courseware; (2) hands-on experience with this courseware; (3) development of an instructional unit in which courseware integration is realized; (4) execution and observation, by colleagues, of this unit; and (5) reflection and revision. The aim of the training is to improve the skills and confidence of teachers in computer use, and to stimulate the interaction between teachers in exploring and realizing computer integration in their teaching practice.
