All the partners, the schools from Greece, Czech Republic, Italy, Lithuania, Spain and Portugal, have decided to cooperate in this project because we think that collective effort is more productive and apparently more pleasant than any individual one.Water is one of the most significant environmental factors for life itself on the planet Earth, inseparably connected to the development of human civilisation. All the hometowns of the partners are located close to a lake, a river or the sea. Throughout the ages, the lives of the inhabitants of these areas are connected with the water in every aspect and daily activity and as a result the city and the water factor are inextricably linked together in a way that the one cannot exist without the other. Moreover, our age is extremely digital. The pupils should be highly efficient in ICTs to perform well during the learning process and their future social and professional life. Likewise, the teachers should learn how to use all the advantages that ICT offers during the educational process.Considering all the above, we have defined our objectives. The pupils and teachers should study the water factor near them in terms of geography, history, cultural heritage, environment, ecology, economy, tourism and art. They should improve their digital abilities and their proficiency in English, develop their critical thinking and cooperative skills, improve their self-expression techniques, obtain an ecological conscience, be aware of the cultural diversity in Europe, develop an intercultural communication and collaboration and participate actively in public life. Furthermore, we have included in our objectives the development and application of innovative techniques in education, the use of attractive teaching techniques and the expansion of the pupils' professional horizon.There are six schools in our project, all participating as equal partners. The pupils and teachers of each school are the ones to implement the activities of the project. Our project involves about 270 pupils, aged 12-15 years old and approximately 80 teachers. About 200 parents’ pupils will also participate mostly by offering their hospitality to the guest pupils during the meetings. Our project includes 6 meetings, one in each school, combining Short-term exchanges of group of pupils and Short-term joint staff training events. The working material, basic for the collective study and activities of the project must be produced before each meeting by each school, while during the meetings a wide range of activities will undoubtedly lead to the successful accomplishment of our goals. The pupils will have to study the water factor near their hometown, take part in workshops, in-class learning processes, presentations, games, theatrical performances, dances, field trips to get acquainted to the water factor and the related activities to it. The teachers will have to take part in workshops too, meetings, presentations, exploratory studies, in-class job shadowing and field trips to the water related sights. The participating pupils and teachers will acquire plenty of knowledge about the water factor near their hometown and they will deeply understand the dynamic relation and its great importance between the city and the water. They will supplement their digital skills, create digital products, improve their proficiency in English, get acquainted to innovative educational practices and attractive teaching methods, improve their abilities in self-expression and group working. They will also be familiar with the other partners' language, be able to recognize the linguistic, national, social and cultural diversity in Europe and finally they will be able to develop an intercultural collaboration between them. In conclusion, there will be longer term benefits to all the people involved in. For the pupils, these will be the improvement of their learning capacity, a sense of self-completion and an expanding of their professional horizon. The benefits to the teachers will be the expected improvement not only in personal level but in professional as well. Moreover, the awareness of the linguistic and cultural diversity between them will help them acquire a greater understanding and respect about other people's culture and traditions and they will gradually become modern European citizens focused on the future. Finally, a longer term benefit to the schools in this partnership will actually be the creation of a modern environment, one that can incorporate all the new teaching and learning methods.
