The Erasmus+ Project “ The European Citizenship through the Arts and Languages” is born of a common desire between French and Romanian schools to give their pupils benefits from a European culture and linguistic openness but also allow the teams to develop their cultural knowledge, pedagogical practices, didactic knowledge and their linguistic proficiency. The Louis Guillet Elementary school of La Rochelle is situated in REP+(Priority Education Zone) wanted to coordinate a project within the framework of the Erasmus+ program following the implementation of the “Orchestra at School” project in September 2017, in partnership with the Conservatory of Music and Dance Agglomeration Municipality of La Rochelle. It enabled all the pupils to benefit from cultural openness; Many educational projects are conducted with the school: 1. Cultural Excursions ( concerts, cinema, theatre plays, museums, national monuments, etc). 2. Partner with local recreation and cultural structures ( Media library, Toy library, Recreation center). 3. Artistic and cultural courses for the youth of La Rochelle. The school also reflects on the continuity of the courses from kindergarten to high school for joint actions: Reading offered by the older kids to the younger ones and vice-versa, action research in Mathematics with secondary school pupils, joint work with the teachers in Science, French, Physical Education (P.E) and Languages from secondary schools. The Romanian school is located in Timisoara, European Cultural capital in 2021. This school is enrolled in an Erasmus+ KA1, they have already participated and organized a national competition for painting, drawing, and writing. Foreign language learning and discovering other cultures is in the forefront of their priorities. The project encourages federating and motivating, is an opportunity for pupils to discover other cultures and develop artistic, linguistic, digital and social skills. The educators will enrich their professional and cultural experiences. The project is innovative because it includes conservatoire teachers and all teachers. It aims to develop exchanges between students through mobility and new communication tools. It creates real cooperation between pupils and teachers of different cultures for the implementation of artistic activities. A two year retroplanning was designed based on a progression to mention all the activities, exchanges, and actions planned for the project. Planned actions and activities will be integrated with learning in various disciplines. They are upstream thoughts by the teachers discussed during the framing up meetings. They are prepared in classrooms with the pupils and then are the basis of exchanges with the other countries. Contacts will be done on a regular bases. When mobilities ( the students that leave on exchange) return, assessments and observations will be made in classrooms with all children and adjustments will be considered. Teachers will develop professional skills by exchanging class observations, artistic and linguistic practices, prevention of school drop out, and giving space to parents and external partners. The creation of a digital working space will allow federator. New progressions and programming will be drafted according to the observation made. The project aims at valuing each pupil by reinforcing confidentiality and self-esteem. Through exchanges, pupils will improve their artistic skills, linguistic skills( mastery of language activities in foreign languages), language skills( expression and comprehension, clear, adapted and precise statements) and mastery of ICT. Working together will improve living together( self-help, tolerance, trust, autonomy, and initiative). By discovering other languages, pupils will increase their knowledge and mastery of the language of schooling. They will discover and wonder about other cultures. They will be sensitive to new languages and ways of living. Through concrete actions, the project indurated the motivation and value the pupils with special needs.Health conditions had a strong impact on the project: Romanian schools remained closed until the end of the first quarter of 2021. The Timisoara school was therefore unable to carry out activities with the students. The Louis Guillet school has, for its part, produced several sound recordings (songs) which were transmitted by mail to the partner school.The planned mobilities could not take place: the French National Education did not allow any outings or trips either in France or abroad for teachers or students.The Timisoara school would have liked to extend the project for another six months, but we did not want to follow up. Indeed, the students who had mostly invested themselves around the project went to college and the orchestra.The students invested themselves with enthusiasm, were very disappointed not to be able to go to the end of the project: it remained virtual and the planned meeting was not possible.
