A Window for a Purpose: Developing a Framework for Describing Effective Science Teaching and Learning

This paper describes the development of a framework - the SIS Components - for describing effective teaching and learning in science, to support a system wide change initiative. The methodology used and the analysis that led to their refinement, is traced to expose the different issues involved in constructing the notion of effective practice. These issues have to do with purpose, politics and audience. They determine features of the framework such as specificity, elements focused on, and the support structures that are put in place to establish the particular discourse being promoted. The paper describes the different research methods used to establish, to promote and to validate the components, and outlines the different senses in which this and any framework can be seen as contingent on the setting for which it is intended.
