Education research has confirmed the need for innovative approaches to teacher professional development and pre-service training, especially to improve teaching and learning in geography and science, technology, engineering and mathematics (STEM) disciplines. In providing high quality teaching about complex issues in Europe, it is critically important for teachers to have sound content knowledge, pedagogical awareness, pedagogical content knowledge, curricular knowledge, and knowledge of learners to be effective in the classroom. The primary objective of the GeoCapabilities 2: Teachers as curriculum leaders Comenius multilateral project will be to create a teacher training course to develop teachers as curriculum leaders in European geography education, through a ‘Capabilities’ approach. This approach asks teachers, curriculum developers and education policymakers to critically assess the role of education in providing students with intellectual, moral, and existential capabilities for lifelong learning, economic and social agency in citizenship, and the pursuit of personal well-being.The main outputs of the project will be to develop and pilot an online professional development communications platform for teacher preparation in geography. This will supply resources (instructional materials, multimedia and Cloud-based communication tools) to enhance geography teacher preparation in Europe and support trans-European collaborations and online exchanges among teachers and teacher professional development programs .The impact of GeoCapabilities 2 will assist national systems by providing a complementary approach to competence-based curricula, which too often focus on educational outputs at the expense of helping teachers reach a better understanding of educational aims. A ‘capabilities’ approach will therefore offer teachers a more holistic perspective of their discipline, thereby enhancing their capacities for leadership and curriculum making.
