Saint-Louis is a high school located in Brittany, France, with around 1 000 students aged 14 to 19. The teachers have noticed that the pupils have many problems related to health. The situation has been assessed through a qualitative study and a quantitative one. Students are tired and stressed and sometimes feel bad. They have bad lifestyle habits and this has consequences on their performance at school. We have searched some partners who had to cope with similar problems. Three schools located in Kiel (Germany), Pärnu (Estonia) and Budakeszi (Hungary) have joined us. According to the World Health Organization, health is "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Mental health is "a state of well-being in which every individual realizes his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community". Therefore, it is essential to help students to take care of them in their everyday life. That's why we intend to highlight the importance of sport, safe behaviour, healthy food and biorhythm. We would like students to embrace the WHO 's idea that "sport is often mistakenly used as synonym for physical activity but this is not the case". It also includes “all forms of physical activity which, through casual or organized participation, aim at expressing or improving physical fitness and mental wellbeing, forming social relationships or obtaining results in competition at all levels." The project will use health and well-being to get our students and more generally young people to play and learn together about : • the importance of a healthy lifestyle and sport • key competences : improving language and ICT learning, reinforcing creativity and socialization • the European culture and citizenship Staff will develop improved teaching and practices thanks to innovative educational approaches such as learning by playing and making students actors in designing and implementing activities. ICT will be used extensively for communication, planning, collaborative learning, dissemination. The 4 partner countries will recruit 12 participants each year from diverse backgrounds : both male and female students, aged 14 to 17 (144 pupils involved throughout the 3 years). The learning activities will be held twice or three times a year. We have chosen some quantitative and qualitative indicators of achievement (surveys, CEFR indicators to measure the students' English level...). We expect the following results: • a common blog, • a common logo and motto designed by students, • videos about professional eating habits and preparation of food, • an exhibition about students’ lifestyles, eating habits and physical activities, • a lecture for parents held by dietician or health professionals, • an exhibition and a digital guidebook about positive influence of physical activity on health, healthy biorhythm, eating habits, risky behaviours and new unhealthy products • a board game with cards • Digital web-based games (quizzes, crosswords…) • Tournaments and grassroots events for the participating students • A Report about a local or national event related to food and eating habits • A written menu and a well-balanced meal to be prepared by students and shared by students, teachers and parents • A Digital portfolio to keep track of the experiences and skills obtained thanks to our project. It should lead to the following long-term potential benefits : We intend to raise our students' awareness on the importance of healthy habits and modify their behaviour. Healthier and more balanced students will be more focused. This will enable them to improve their school performances and therefore their skills. Pupils will strengthen their social and personal skills such as self-confidence, their capacity to take initiative. We will use intensively ICT throughout our activities. Particularly, we will emphasise the importance of a relevant use of a digital portfolio. It will reinforce their employability and make it easier for them to get on the labour market. It is also an efficient way to avoid early school leaving. Our projects seeks to enhance European understanding through language and cultural study; to embed outward mobility better within programs that go beyond traditional short stays abroad in host families. Our Open Educational Resources will be shared with the educational community on the European platform.
