The 5th General Lyceum of Veria found out that some students were not involved in the learning process because they failed to meet the requirements of teaching practices which are limited to the teaching of the examination syllabus. Wishing to address the possible marginalization of these students and make the learning process attractive and useful for all students, the school considered that it was necessary for the teachers to develop their ICT skills in order to integrate them in innovative teaching methods. The school wished its teachers to make use of the school technology equipment in order to combine the traditional classroom teaching with online learning (Blended Learning) and implement practices that reverse the traditional direction of teaching (curriculum delivery in class - studying and practicing at home) by adopting the model of the reverse process (Flipped Classroom). For this reason, the school trained some of its teachers in New Technologies (Web 2.0, Social Networking, Blogging, Website creation) and create teaching conditions that suit a modern European school. The school aimed a) to use ICT constructively in the teaching process so that it meets the needs and caters for the learning styles of students, aged 16-18, b) to enhance the quality of cooperation with other European schools, by exchanging ideas and similar practices which will improve its education quality, and c) to disseminate the knowledge and the benefits of the participation in this activity to the local educational community The group of the four teachers - two teachers of English , a Greek Language & Literature teacher and a Social Studies teacher - , who participated in the training seminars in Europe, were selected on the basis of their very good English language skills and the need to improve their knowledge in ICT, since they had not participated in the Second Level of the in-service training in ICT. Given the European quality of the activities, their involvement in European and national programs, their ability to work as a team and especially their effectiveness and willingness to share and transmit knowledge to the rest of the school teachers played a significant role in their selection. In cooperation with the selected European training organizations, the school saw to the preparation of the participants and conducted a research, by using a questionnaire (pre-assessment) to find out to what extent the school students can participate in Digital lessons / Networking classes. In addition, during pedagogical meetings of the School Board the school looked into the expectations of its teachers from the training programme and set out the necessary actions for the implementation of the project. The training seminars were held in Malta and in Spain. During that period the European hosting organizations organized daily courses that included theoretical lectures, collaborative workshops, design and implementation projects in groups and simulation teaching practices . In addition to the program of training, these organizations planned and held cultural activities with a view to strengthening intercultural relations between the participants and promoting European cooperation. The learning results, activities and classroom projects that the participants prepared during the seminars were published on the school website and blog (http://5lyk-veroias.ima.sch.gr/index.php/erasmus/erasmus-ka1& http://blogs.sch.gr/5lykvero/archives/category/erasmus/erasmus-ka1), in the local Press and were also disseminated through the platform of eTwinning and Erasmus+ Project Results Platform to form the basis for partnerships and cooperation with the European educational community. Wishing to determine the effectiveness of the new teaching tools and methods, the school used them on an experimental basis in a real teaching context and evaluated their implementation potentials by considering the students' response to the new teaching experience. In addition, the school organized training and dissemination sessions for both its teachers - so that all of them could have the opportunity to be informed and apply innovative methods and tools of ICT in their lessons - and the local educational community on the whole . The implementation of the European school development plan had a positive impact on the students and the school teachers, all of whom improved professionally by having been involved in its application.The school, through its dissemination activities, provided a realistic practice of differentiation and innovation in teaching for the entire educational community.
