Curtin University of Technology has initiated Collaborative Science, a project to develop various modules on science teaching for pre-service early childhood teachers. The modules will be designed to help them integrate knowledge of science content with their pedagogical skills. Scientists, engineers and teacher educators will work with a cohort of pre-service early childhood teachers within a science curriculum and instruction unit. The teaching materials they develop will be used and evaluated by the pre-service teachers, as well as experienced early childhood teachers and science teacher educators.
