The present Project is based on the study of History and Literature according to the EsaBac and the BachiBac programs, the improvement of the student’s language skills and the deepening of the knowledge of the culture and the civilization of France, Italy and Spain, the European construction process and, as well, to change the methodology and the perception of the importance of these programs for each center. These objectives will be reached thanks to teacher’s meetings, exchange visits among the three High Schools and researches made by the students. Teachers will focus on the elaboration of didactic materials for the EsaBac and the Bachibac programs as to achieve the challenge that these programs imply, meanwhile students will analyse the European construction process in the three countries and they will work on a field study about the sense of the European citizenship in their respective countries. The vehicular language of the Project is French as it is the common one for the three countries. The three High Schools participating in this Project: Lycée Molière of Paris, Liceo Virgilio of Rome and the IES San Isidro of Madrid are pioneers in the implementation of the ESABAC and BACCHIBAC programs in their countries, clearly placing high expectations on the improvement of the language skills and the promotion of intercultural understanding. That’s why they are reference centers for other High Schools. Moreover the three High Schools have a lot of characteristics in common as they are located downtown with a rich historical and artistic heritage.
