The project is a cooperation of 4 schools from 3 different countries: Croatia, Slovakia and Spain. The aim is to extend our previous project results and outcomes which were focused on reading literacy. Tangible results of the project activities will be presented within The Case Study containing LTTA activities and mutual Integrated curriculum as the results of Expert-Teachers Open Class encompassing 4 subject areas: Media literacy, Finance, Science and Mathematics literacy. Intangible results will be reflected in the change of social and educational ethos whenever the benefits of integration teachings come into the focus of the educational policy decision makers. Expert-teachers will, during the exchange a good practice and LTTA activities, turn toward intergrated curriculum that is situated in a real-life context. The teachers will be charged with having to create challenging, fun, meaningful tasks.
