Our school, with 330 students and 36 specially assessed members of staff, located in a disadvantaged area, is supervised by the English Department of Aristotle University of Thessaloniki and implements a programme of enhanced English Language teaching. At the same time, innovative programmes, international cooperations and research take place aiming at the holistic development of our learners' abilities, skills, knowledge, attitude and behaviour as well as their preparation as future European citizens. As a Model Experimental School, we implement, evaluate and propose to the Ministry of Education teaching practices that could be adopted by the majority of schools in the country. This presupposes the constant training and professional development of our staff. The Board of Staff has decided to apply for the attendance of training seminars by 15 educators (of all specialisations) because, due to the extensive workload at the specific school, all seminars organised by us take place after teaching hours. Since we intend to organise a series of in-school and cross-schools actions (as we do every year), it is understandable that one single educator would find it difficult to cope with such a project. Thus, with reference to Erasmus+, we ask that they attend programmes of - Creative Thinking and Inquiry-based Learning, 4 educators (2 persons in each), with the aim of enriching the teaching process and forming a context of learning through participation and discovery, leading to the learners' autonomy and self-motivation. - CLIL , 4 educators (2 persons in each), who are already implementing content and language teaching, so that they can exchange information with European colleagues conducting similar research in their countries, to compare, redefine, adapt but also extend what they have applied at an experimental level so far. -Museum Education, 3 educators, who, despite their personal interest, lack the know-how necessary in their effort to guide learners towards the realisation of their national identity and heritage but also of the coexistence and interaction with other cultures, aiming at the acceptance of the idea of an extended European family. -New Technologies, 3 educators, who need to familiarise themselves with interactive learning tools so as to be able to assist their fellow teachers with the implementation of innovative teaching practices for all subjects. -Administrative English, our headmaster,so as to familiarise himself with the use of related jargon and enhance his oral skills in English. The school representative, the trainees and the training institutions will cooperate at all stages of the seminars. Prior to their arrival at the seminars, the participants will receive help with the use of English, information material, as well as aid with the practical issues of their travel and accommodation in the host country. During the seminars, participants commit to consistently attend the courses and work closely with other participants, while the organising institutions commit to provide quality work and cater for he participants' needs. On completion of the programmes, the training institutions will assume a supporting role through the internet for all participants. The trainees commit to organise seminars so as to disseminate the results of their training to their colleagues back home. Following the completion of the seminars, the participants are expected to be able to employ a wide spectrum of technological tools, strategies related to museum education on a variety of subjects, creative and inquiry-based learning techniques, as well as to continue teaching English through content learning empowered with additional skills. Their interaction with European colleagues will enhance the ease in foreign language communication but will also encourage them towards transferring to their students the value of their own culture and the respect to different ones. These mobilities will benefit the wider educational community but mainly the learners. The introduction of new practices will add to the special nature of the education provided in our school, with emphasis on cultivating students who are autonomous, creative, and open-minded, and have an exploratory attitude toward things as well as a multicultural orientation.
