<< Objectives >>The project promotes interest in science, technology and green skills through an increase in both the quantity and the quality of STEAM in schools. To ensure that future-oriented, sustainability-based green STEAM becomes an entrenched part of the education landscape to fulfill local economic and societal needs, the project establishes local green STEAM ecosystems in partner regions with the help of regional authorities, education providers, businesses, and other stakeholders.<< Implementation >>The activities fall into three main categories:1. STEAM practice in schools (The What): The development of green STEAM teaching practices, methods, and materials.2. Teacher competence building in STEAM (The How): The development of green STEAM teacher training modules for in- and pre-service training.3. Local STEAM ecosystem building (The Why): The development of local collaboration platforms for schools, regions, businesses and other stakeholders to keep STEAM locally relevant.<< Results >>The project will result in marked expansion of STEAM in participating schools and regions, improved teacher abilities in sustainable STEAM through specific green STEAM training, and a network of four functioning STEAM ecosystems in the Baltic Sea region. It will also produce the Green STEAM Handbook, which will include the best teaching practices developed in the project, a model for green STEAM teacher training, and a guide to entrenching STEAM through local ecosystem building.
