3.2. The project
The project was designed in such a way that 1) teachers were
invited to develop curriculum units closely related to teachers' daily
teaching practice and teachers' own needs; 2) teachers worked in
close collaboration with colleagues. The school management was
supposed to support the project by, for example, facilitating the
participating teachers, who were appointed by their management
on the basis of their initial interest in citizenship education, to
enable them to invest enough time in the project, and in addition
the project needed to be aligned with school policy (Meijer et al.,
2013; Van Veen, Zwart, & Meirink, 2011).
