The main focus of this work is on didactic planning (in high schools) with a special emphasis on the following topics: the use of problem-solving and social media in a course centered on scientific knowledge, participatory and collaborative activities, on and off line, the paradigms of collective intelligence (), and connective intelligence (, ) and technical skills. The work methodology includes the creation of an integrated educational environment functional to the promotion of process-based learning for the presence of learning practices in the formal didactic setting taken from non-formal or informal contexts, as suggested by Luciano . The leading hypothesis of the work is concerned with the participatory practices (production-sharing-socialization) which are used in a structured learning context and on their effects: a) to increase the degree of interest and involvement of the students and, b) to have a positive effect on subject knowledge (learning history), and cross-curricular knowledge (responsible use of technologies).
