The main aim of the project is to establish the first Croatian open-air school in Kalnik by applying Hungarian experience with environmental education. An extended system of open-air schools already exists in Hungary, which would form the basis for the creation of a similar system on the Croatian side as well. Within the project a joint curriculum will be developed, a joint feasibility study and a bilingual web portal will be elaborated and four-day training seminars for potential open-air school teachers will be organised. Achievements: The connection that the two neighbouring countries share can be seen in their geographical features, too – it was exactly this, the similar botanical, zoological and geological characteristics of the Kalnik and the Mecsek areas that acted as the starting point for a joint project in setting up the fi rst Croatian open air school. With the support of the years of experience of the Hungarian partner, a place for active learning for the children of the region was established, a curriculum developed and several information days and training sessions for the Croatian teachers held.
