Nowadays the schools' main objective is to prepare the youth to pass difficult final and vocational exams. The schools also struggle for high ranking positions. Meanwhile, they have problems to meet the pedagogical needs and develop prosocial attitudes among students. Analyzing the current situation in schools - Poland, Italy, Spain, Greece and Portugal came to conclusion that also their students who are in the age of 15-19, have different social problems.They do not cope with bullying, aggression, e-addictions which often result in bad eating habits and lack of physical movement. In relations with their peers they cannot be assertive, defend their rights and react to any discrimination. The youth often escape into the virtual world, which makes them insensitive to the problems around them or help for others. All the negative aspects disturb proper functioning of young people, which is reflected in their school performance, self-esteem, and being active at school. The intensity, range and attitudes to the problems in partner schools are different. Therefore we started the cooperation during which we want to exchange the expert knowledge about preventing and solving the problems. Following the words said by Stephen Hawking ‘The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge” the partners decided to verify their knowledge about social problems in schools and broaden it by different solutions existing in other parts of Europe. In the project ‘The Guardians of Europe’ five schools became five ‘Guardians’ of the European values and they will share their expert knowledge about equality, healthy eating habits, cyber safety, tolerance and physical activity. The social campaigns which will be conducted together will become a bridge for their activities and will encourage prosocial attitudes among the project participants. Thanks to them the participants will also develop creativity, team work, entrepreneurship.They will learn how to cooperate with the media and will develop new IT and language competences. The climax of the international cooperation will be the international social campaign divided into two parts and the event ‘You don’t know it – get to know it, if you know it – preserve it’. The mission of ‘the guardians’ will be to encourage young people to explore and preserve the European cultural heritage for the next generations. The challange and task for the teachers will be to learn how to teach about heritage and how to use the knowledge during the different lessons. The School Corners will be created in the schools. They will be the centres for students’ dialogue and social activity where young people will work on social campaigns and report their acitivities on eTwinning platform. To achieve the objectives we will use different methods like brainstorm, SWOT and SMART analyses, the Ghant’s Graph’, workshops. Teachers as mentors and tutors of the School Corner will develop lesson plans about social issues which will be included in the prevention programs in partner schools. To reach the local community we will organize The International Festival of Social Campaigns, School Days of European Heritage and the International Social Campaign about Heritage. We will create the five figures of guardians as patrons of our campaigns: ‘The guardian of healthy eating habits, the guardian of physical activity’, the guardian of equality’, the guardian of cyber safety’ and the guardian of tolerance’. We will create „Proclamation of Guardians” a public announcement about fighting with social problems. In order to achieve the objectives of the project we will organise five student project meetings to discover the European heritage on their own and one staff training meeting which will allow the teachers to receive training and mentoring from experts to implement the technical part of the campaigns properly.The project will refresh the quality of educational activities in schools by multicultural cooperation. It will introduce a new method of social campaigns which will activate students. It will positively influence prosocial attitudes and the European quality of life. It will encourage Europeans to care about healthy eating habits, physical activity, cyber safety, equality and tolerance. The project activities will raise awareness that we need to preserve European heritage for future generations.
