All the courses will increase versatile competences of the PARTICIPANTS: professional, methodological, interpersonal in regard to student-teacher relations, linguistic and personal. Therefore, the STUDENTS will gain significantly as they will be taught by teachers with enriched methodological background. Moreover, their contact with foreign language will be greater due to CLIL method being introduced in the classroom. The work quality of the SCHOOL will raise due to professional upskilling of the teachers, introducing activating methods, enriching the offer of extracurricular classes incorporating foreign languages (day room, homework club, scouts club, interest clubs, social skills workshops). Popularizing educational mobility among students will highlight the benefits of learning foreign languages – open borders concerning education, employment in EU countries and international cooperation. Establishing cooperation with EU schools, leading to future teacher mobility and student exchange, will make the educational offer of the school more attractive and will raise the prestige of the school in the local environment. In result, it will have a beneficial effect on the LOCAL EDUCATION image while implementing the Strategy of Educational Development in Piaseczno district – we will enlarge the group of schools with European standards.
