The overall aim of the EC call is building up a scientifically literate society, which enables its citizens to participate in the research and innovation process as part of Responsible Research and Innovation (RRI). This calls for democratic citizenship education, in which two educational approaches, often presented independently in schools, are integrated, viz. Inquiry-Based Science Education (IBSE) and Socio-Scientific Issues-Based Learning (SSI). We call this integrated approach Socio-Scientific Inquiry-Based Learning (SSIBL). The aim of the project is to collect and share existing best practices across Europe and develop learning tools, materials and in/pre-service training courses for science teachers based on the SSIBL approach.This educational methodology promotes democratic citizenship through the integration of social issues and related scientific knowledge. Our aim is to empower and facilitate science teachers and teacher educators, by in-service and pre-service professional development courses, based on reshaped best practices available among the partners.These shared selected best practices will be reflected on from an RRI perspective and improved by an international ‘community of learners’ who incorporate RRI in their teaching and learning processes. The project will establish a multidisciplinary team and facilitate networking activities among teachers, teacher educators and educational researchers of 18 institutions in 11 countries. In addition, the project will build on recently developed IBSE insights and foster implementation of IBSE in educational practice.
