A case study of the development of a beginning chemistry teacher's knowledge about models and modelling

Abstract

In this paper, we present a case study of a beginning chemistry teacher who enrolled in a project aimed to contribute to the development of teachers' knowledge of models and modelling in science. The project consisted of a series of institutional meetings in combination with an action research project the teacher conducted in her own classes. By explaining how the project was conducted and mainly by focusing on the teacher's voice, her dynamic, continuous, and non-linear process of knowledge development is discussed in detail. We were able to investigate and describe this development in terms of various types of knowledge - content knowledge, curricular knowledge and pedagogical content know..
