Our schools should be incubators of exploration and invention. They should be accelerators of innovation. They should promote Open Schooling. School leaders should set a vision for creating learning experiences that provide the right tools and supports for all learners to thrive. Teachers should be collaborators in learning, seeking new knowledge and constantly acquiring new skills alongside their students. A holistic approach to innovation is needed. We need to facilitate the process with a provision of the necessary catalyst: This is the foreseen role of the OSOS Coordination Action, to describe and implement at scale a process that will facilitate the transformation of schools to innovative ecosystems, acting as shared sites of science learning for which leaders, teachers, students and the local community share responsibility, over which they share authority, and from which they all benefit through the increase of their communities’ science capital and the development of responsible citizenship. In this framework the proposed coordination action is aiming to support a large number of European schools to implement Open Schooling approaches by a) developing a model that promote such a culture, b) offering guidelines and advice on issues such as staff development, redesigning time, and partnerships with relevant organisations (local industries, research organisations, parents associations and policy makers), and c) suggesting a range of possible implementation processes from small-scale prototypes through to setting up an “open school within a school” or even designing a new school while it is testing and assessing them in more than 1,000 school environments in 12 European countries. The themes of the project activities developed and pursuit in participating schools that will take place will focus on areas of science linked with the Grand Societal Challenges as shaped by the EC, will be related to RRI and will link with regional and local issues of interest.
