In Chain courses the central concept regarding content is cultural heritage as an integrating element. All aspects of human existence - determinant factors for this existence as well as the outcomes of human endeavour and creativity - can be connected to this central concept. Landscape (natural as well as human-arranged), built environment, literature, food, religious ideas, music, mathematics and many more aspects fit into this definition. Therefore cultural heritage is also a perfect vehicle to connect and integrate the various school subjects.

A key element in each Chain course is joint production. As the mikro-equivalent of mankind creating culture, each course group is invited to express the course content in various forms of artistic expression: drama, visual arts, music, poetry, film and photography etcetera. This is not something 'afterwards', but a basic incentive to learn: never a topic will come as near to you as when you, e.g., have to perform this in a drama production for a group. (more in article).
