The course briefly discusses contemporary theories that highlight the need for collaboration between contexts in the educational process. Basic theoretical approaches are presented for understanding the conditions and processes of collaboration between individuals and contexts, in the context of enhancing children’s education and school effectiveness. The characteristics and skills of teachers that create a positive climate in the classroom and the school unit and enhance interaction with the family and social environment are analyzed. Examples of applications and findings of relevant research are presented with the aim of highlighting the factors that facilitate but also hinder collaborative relationships in school. Finally, students are invited to design their own actions/programs to strengthen the school-family-community relationship and positive relationships in school or to carry out a brief relevant research project.
