The challenges of a complex and volatile world require solutions that reconcile divergent perspectives and interests. In schools, interdisciplinarity has been integrated within curricula for decades, yet it is rarely applied as a collaborative practice. Communication between different fields of research is not enough. Without meaningful collaboration, opportunities to connect are lost, and teachers and students fail to benefit from the experience of lived interdisciplinarity. A new periodical, entitled , presents the latest findings of national and international transversal research as well as the state of the art of interdisciplinarity in didactics. The aim of this annual publication is to stimulate a transversal turn in education.
