With the project “Social and economic changes dictate the need for new professional knowledge”, within the program Erasmus + (KA1), we achieved 27 mobilities of students and 23 mobilities of teachers, mostly teachers of practical education and training as the aiming project group to their professional and technical training in the fields of mechanical engineering/car mechanics, logistics and textile at partner institutions and companies in Finland (Vaasa, Mikkeli and Tampere), Spain (Zaragoza and Madrid), Denmark (Sonderborg), Hungary (Kecskemet), Malta (Paola) and Estonia (Tallinn). These are all secondary vocational and technical schools with vast experience in carrying out the international projects and international students and teachers’ mobilities. We have been actively and successfully cooperating with most of these schools for some years now. In this project we established a new cooperation with Spanish school in Zaragoza, with additional new Spanish school in Madrid and the Maltese school in Paola. The purpose of our project was to implement an innovative organisational model for students and teachers' training in technologically more developed foreign environment, so that Slovene students and teachers trained at the same time and worked together with foreign students and teachers in schools' workshops and companies (model 1+1+1+1). This creates new forms of interaction between all participants in the process of training, increases motivation to work and enables complex acquisition of new professional competences, knowledge and skills as a respond to current social and economic changes. It is an innovative training model based on current methods/approaches of training for both, students and teachers. The students gained the enriched transfer of knowledge and competences for entering the labour market. This also strengthened the cooperation with the economic sphere and the social partners. The aims of the project were the following: a) The students and teachers of practical education and training gain new knowledge, experience and skills with the focus on their professional competences and qualifications; b) The recognition of theoretical and practical methods and forms of work, and the implementation of educational work in related programmes in host countries. We achieved an increase in the attractiveness of vocational education and training systems; c) Acquiring the language basics of the hosting country, learning/improving the foreign (English) language for specific purposes connected with their professional needs, recognizing cultural and traditional characteristics of the hosting country (recognition of informal learning); d) Intensification of international cooperation between institutions that are involved in education for the professions, which are the subject of students and practical training teachers’ mobilities. This also improved the quality and increased mobility; e) Cooperation with foreign companies and social partners, where our students and teachers are trained during the time of exchange/mobility period. The pedagogical, cultural and linguistic preparation for students and teachers was a part of the project. The final project evaluation showed that we achieved all the set objectives of the project, realized two students' and eight teachers' mobilities more than we had planned and established a project cooperation with three new vocational schools. The organizational model of practical classes (1+1+1+1), which was introduced and tested in this innovative project, has proved successful and as an example of good practice in implementing the mobility of students and teachers of practical training, also in the future.
