In 2000 a consortium headed by Deakin University was funded by the Victorian Department of Education, Employment and Training to develop a model of effective teaching and learning for science in schools from P-10. Initially working with 27 study schools, the Project has continued in 2001 with 126 participating schools. This paper will discuss the model for school and classroom change that we have been developing, with a particular focus on the change strategies being used by the research team and in the participating schools. Central to the model has been the appointment in each school of a SiS (Science in Schools) coordinator with time release and additional funding for resources. The Coordinator has used strategies including mapping each participating teacher against the eight components of effective teaching and learning (the SiS components); student preferences surveying; auditing of curriculum, resources and school policy; and team planning of priorities, actions, implementation and monitoring strategies. The emphasis has been on school ownership of the change process and the school leadership has been identified as central to its success. As well as focusing on actions in schools the paper will also discuss the research process from the research team's perspective.
