GEO-Academy aims to create a European network offering a comprehensive teacher training and development program which will provide pre- and in-service teachers opportunities for professional learning and development by using an efficient pedagogical approach aiming at holistically educating the next generation of European citizens on Sustainable Development topics. The consortium (12 partners from 7 EU countries) will establish a network and a community of practice to develop innovative strategies and learning modules for preparatory and continuous professional development for in-service and pre-service teachers on new innovative digital technologies upon competence-based educational pedagogies. The ultimate goal is to prepare the groundwork for a unified framework to foster teachers’ pedagogical, digital, green and spatial skills needed to succeed as incubator staff and at running an accelerator for successful Education for Sustainable Development (ESD) programs in the respective countries and beyond. To utilize cutting edge geo-technologies, GEO-Academy aims to support the introduction of Geographic Information Systems (GIS), Remote Sensing (RS) and Earth Observation (EO) along with Geospatial Storytelling, through tools and materials freely accessible to all education institutions across Europe. The resources will be jointly developed by the consortium, designed to be easily attained, adopted and replicated, using state-of-the art educational approaches, methodologies and tools, with teachers acting as reflective professionals with roles both as trainees and co-designers. The material will be developed in English, German, Portuguese, Greek, Bulgarian and French. It will be the yeast of the GEO-Academy acting as hub for upskilling teachers’ pedagogical, green, digital and spatial skills to support students’ learning. During its lifecycle, GΕΟ-Academy will usher the activities through online, physical and blended training across Europe.
