The high school Louis Armand located in Chambéry is a General and Technological High School. It provides various educational paths in order to complete the Baccalauréat général, série ES (economic and social sciences), L (Literature), S (Sciences) and the technological Baccalauréat, STI2D (engineering) and STL (biochemistry). Despite its location in an underprivileged urban environment, the high school gathers pupils of a large social diversity thanks to the teaching diversity. For years, the high school Louis Armand has developed many international, cultural and professional actions in order to increase the motivation of its students and to limit the number of pupils who could drop out of school. Specific teaching activities have been promoted to reach this goal, including an audio-visual section, a European section with two CLIL (history-geography and physical sciences), and a "citizenship and defense" option. However, these actions remain traditional methods developed in French schools. From now on, the high school yearns to develop another dimension of its pupils motivation being inspired by various European models. This staff mobility project corresponds to the next stage which will lead to innovating educational methods. Ultimately, we would develop student mobility (through ERASMUS+ K2 project, cultural exchanges, participative works between several European schools, participation in international film festivals). In order to meet these requirements, our team in charge of international development has set up a strategy of mobility and staff training directly link to these new needs : - Structured course offering a large part of observation and seminars on other European educational systems; - One week observation internship This project represents a good opportunity to renew teaching and management practices. Up to nine teachers plus the high school assistant headmaster will be involved in this project. This team also sets up presentations, broadcasting of the practices observed among the educational teams of the high school but also of the nearby schools within the partnership between the junior-high and high schools partnership, as well as the meetings of the pedagogic area. In the end, through a better commitment and a reinforced training of the teachers and the managerial crew, this project should help the students to be more committed to their education, thanks to the setup of innovative teaching and managerial practices, and would ultimately reduce the dropout of school.
