Thessaloniki’s 4th High School was founded in 1933 and is one of the city’s historic schools. It offers a very high standard of education to the high school age pupils of the historic centre of our city. Today there are 150 Greek, foreign and repatriated Greek pupils and 18 teachers. The school teaching staff constantly tries to improve and enrich its teaching skills, in order to face the challenges in a multi-cultural school.Our headmaster worked on the European Comenius programme with Turkish teachers, and through his contacts, he got in touch with a new experimental school in Ankara, and he suggested the implementation of an Erasmus KA 1 Educational and Teaching programme abroad, which would aim to develop the teaching skills of the staff, and to gain some European ideas.Eight participants were chosen fairly, with the criterion of their wish to gain European experience, their knowledge of languages, skills at using technology, commitment to active participation during the implementation of the plan and the publishing of the results representing all subjects.The activities which were decided on with the Turkish host school were concerned both with preparing the participants before the implementation of the exchange of information, by electronic means, skype, e-twinning, e-mail and facebook, and the evaluation of the specific demands of the plan as well as the organization of educational activities. The activities planned and implemented during the 5 days consisted of teaching presentations by the teachers of our school, in the following subjects:1. History and Culture of Thessaloniki.a. Guide to Thessaloniki and the Important sites.b. Ottoman buildings and monuments of Thessaloniki.2. Natural Sciencea. Use of internet maps to teach geography.3. Languagea. Turkish words which have survived in everyday Thessaloniki.b. Teaching of words and phrases in everyday use in the two languages (Greek and Turkish).4. Dancea. Teaching the Greek Kalamatianos dance to Turkish pupils.5. Foreign Languagesa. Presentation of German lesson.b. Presentation of Italian lesson.6. School Administrationa.

Use and function of Interactive Board in the classroom.4. Design and teaching of foreign languages (English, German)5. History and culture of Ankara and Cappadocia areas.The result of this plan was that the participants were able to strengthen their European identity and become aware of the developmental dimensions of the teaching profession. The self-confidence that they gained when they realized that they could teach pupils from a foreign school and convey their scholarly knowledge to fellow teachers from Turkey was very important. They became aware of their ability to participate and take the initiative through the pan-European e-twinning platform. They were able to understand the differences and the many similarities between the two nations. They gained new teaching experiences and skills. They became mentors to spread European development practices by means of the Workshop to talk about the results of the KA 1 programme, organized by our school. Teachers who were interested in getting to know new European teaching realities, offered by the ERASMUS programme, attended thisworkshop. They were also given the Europass Mobility award at the end of the workshop.The European dimension of the school was strengthened in the wider community, and the teachers understood the need for an exchange of correct practices and support between schools and educational districts from all over Europe, andby means of publications and reports in the Newspapers, on websites and social networks of an educational nature, the benefits of participating in this European programme were recognized. It was beneficial for pupils, teachers, parents and foundations (or associations) and it was made possible by the State Scholarship Foundation of Greece.
