Six secondary schools from Finland, France, Germany, Luxembourg, Spain and Slovakia interested in developing a project on debating in school and students´ leadership skills promotion, decided to apply for funding as a strategic partnership. They realise that young people struggle to fit the society, to find the active place as responsible citizens and to meet labour market expectations. Throughout the wide range of project activities, students are given the opportunity to improve their communication skills (argumentation, negotiation, public speaking), critical thinking, negotiation, research, language and digital competences, etc. and collaborate together in the virtual space (in the TwinSpace on e-twinning site) and face-to-face in the multinational debating/youth clubs created at schools or during model conferences with international and multilingual setting (www.zamun.sk). In order to participate and perform well at a conference (where students solve specific international issues as delegates of allocated EU countries), involved teachers together with the students create intellectual outputs, which will be implemented into the club actvities or ordinary lessons in each school and tested as a part of school curriculum, in particular during 2/3-month long-term mobilities of chosen students (30 in a two-year project period). The methodology applied envisages long lasting impact of the project results on wide school community. The partcipating schools organise school debates, local public discussions, simulations of UN or EU conferences and projects in cooperation with local and regional activities and share with the others also after the official end of the project. All the materials developed in the project are published through e-twinnig site, school webpages and ZAMUN website and made available as a source for others who want to conduct a similar project.
