|Abstract:||This study investigated the knowledge that experienced science teachers have of models and modelling in science in the context of a school curriculum innovation project in which the role and the nature of models and modelling in science are emphasized. The subjects in this study were teachers of biology, chemistry and physics preparing for the curriculum innovation. Two instruments were used: a questionnaire with seven open items on models and modelling, which was completed by 15 teachers, and a questionnaire consisting of 32 items on a Likert-type scale (n = 71). Results indicated that the teachers shared the same general definition of models. However, the teachers' content knowledge of models and modelling proved to be limited and diverse. A group of teachers who displayed more pronounced knowledge appeared to have integrated elements of both a positivist and a social constructivist epistemological orientation in their practical knowledge. Implications for the design of teacher education interventions are discussed.|
