This investigation delineates a multi-year action research agenda designed to develop an instructional model for teaching the nature of science (NOS) to preservice science teachers. Our past research strongly supports the use of explicit reflective instructional methods, which includes Thomas Kuhn's notion of learning by ostention and treating…

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…

The use of collaborative case studies is an important tool for promoting teacher development, providing preservice teachers with opportunities to apply what they have learned in a real life context. This paper describes the design and evolution of a unique application of case study methodology by two early childhood/elementary education professors…

Two perspectives on teaching that have framed other inquiries are first discussed: the teacher knowledge perspective,…
