Abstract
Open schooling is a new concept used in policy making based on cooperation between the schools and wider society. Students and teachers in cooperation with other stakeholders are actively involved in solving real-life projects related to important and topical community topics often linked to the environmental sustainability issues like climate change, clean energy or good health and well-being.
Based on the think aloud method - retrospection applied to the experts dealing with open schooling projects in the last year we come up with the information about three clusters of barriers - on the students' side, e.g. differences in the degree to which boys and girls are motivated; on the teachers' side e.g. lack of support from school management; and on the community side, e.g. difficulties in finding appropriate community partner. Because such obstacles need to be overcome in order to successfully implement open schooling projects in schools, we convey experiences of experts and schools on how to deal with these barriers.
