This project investigates the potential contribution of Problem Based Learning to school based Science,Technology, Engineering, Mathematics (STEM) education. The project expects to generate new knowledge about how the principles defining this PBL approach can support primary and secondary teachers to enhance learning opportunities and build STEM literacy. The project actively positions teachers as researchers interrogating their practice. Expected project outcomes include a pedagogical framework developed with teachers, and illustrations of practice capturing problem based learning in a range of school settings. Potential benefits include support for teachers, school leadership and sectors seeking to enhance STEM education.
