Languages open the door to knowledge, friendship and the world ERASMUS PLUS Project is conducted at VIII Prywatne Akademickie Liceum Ogólnokształcące in Kraków, Poland (Academic High School No 8 in Kraków, Poland). It aims at supporting and uplifting the quality of teaching and knowing foreign languages, bilingual teaching methods, IT tools used in the classroom environment by language and subject teachers, tutors as well as school boards which should result in helping Polish students and `sojourn children` to overcome daily (especially bilingual) learning challenges. We believe that by giving a chance to 24 teachers and school educators to take part in European Teaching and Language Courses and to let them get acquainted with teaching methods used in a European schooling (content learning, IT in language classes, self-learning evaluation, student-centre-learning, global learning, subject correlation, content teaching), participants will implement learnt `best practises` into their teaching so as our students might become global learners, who are ready to live and work in the shrinking and globalized world. Some of our students also dream of studying abroad, thus a good teaching board might be the source of great knowledge and guidance for a life-long learning. Besides, `sojourn children` knowing that they learn in a postive, communicative and professional school environment where teachers and boards are familiar with European systems of educations, standards, cultures, active methods of teaching and use IT on regular basis, will assimilate into the school frames smoothly and without too high level of stress. Thanks to the mobilities, teachers and tutors maintain a good communicative thread with `sojourn parents` too. We are confirmed that the project will open the door to knowledge, friendship and the world to all project participants and our students. As a school we wish that educational projects with newly met partners will take place in our school in a form of students mobilities, student-exchanges, web-conferences, cultural events, blog writing. To sum up, because of the project the quality of teaching, learning and creating a students-friendly school environment will lead to become a high quality school which is open to constant changes of XXI century.
