Since 1990, the implementation of the Science at Key Stages 1 and 2 of the National Curriculum in England has exerted a profound impact on the style of inservice training supporting the teaching of science in the primary curriculum. This paper explores the potential of distance learning to deliver inservice training in primary science using evidence from a five year research, development, and training program from the Open University, the Science for Primary Teachers' project. Teachers throughout England participated in this initiative, providing key information through the use of learning files, reflective diaries, questionnaires, and dialogue with course tutors. In addition, teachers produced assignments showing the impact of the science they had learned on their practice. (Author)
