Modernization, innovation and internationalization are the main goals of Krinides Gymnasium, according to its strategic action plan. Therefore, highly qualified staff is required to carry out the changes dictated by the challenges of the future. This project, as part of the above strategic plan, is an attempt to enable the school staff to raise their professional qualifications, to improve the educational process by integrating the skills acquired through mobility, and to expand the opportunities for European cooperation in order to modernize and internationalize the curriculum.The Headmaster and three members of the school staff are taking part in this project. All of them teach different school subjects and in some cases other than their professional specialty. They are people with various interests, actively involved in scientific and cultural associations and part of the task force of the school for innovation and development. The main activities of this project are three structured teachers’ training courses in Finland and Portugal. The first course focuses on benchmarking best practices with emphasis on innovation regarding school policy/curriculum/management, transition to the digital classroom, students’ support, teachers’ in-service training and critical comparison of European school systems. The second course focuses on theoretical and hands-on introduction in game-based learning and the challenges of game play in schools. Classroom observation, workshops and discussions with researchers, teachers and students along with the production of intellectual output are the main methods of both courses. Finally, the third course focuses on the cultural heritage as an integrating element: a vehicle to connect not only peoples but also the school subjects across the curriculum. The concept of Europe, its “edges” and the urge to the West are some of the topics which will be studied through experiential learning.After the mobility activities, participants will be responsible for designing, organizing, carrying out and assessing actions, workshops and projects so as to implement the acquired Knowledge in the school curriculum.The results of this project are expected to be very positive for the school community as a whole. The participants will acquire and improve not only general educational competencies, but will also familiarize with the various inclusive approaches involving children from different cultural backgrounds in the educational process, develop their computer literacy, gain a broader and inclusive understanding of education programs in the European context, acquire knowledge and the ability to plan and carry out international projects, improve communication and collaboration skills working with international partners, and improve their foreign language skills.In the long term, this project will have a significant and beneficial impact on the school policy and practices. The participants will become more open to change and more ready to take initiative in order to modernize the educational process and internationalize the school curriculum. The implementation of the acquired knowledge, skills and attitudes will significantly improve the quality of education, the teaching and learning process, the students’ achievement and consequently the teachers’ job satisfaction. The participants are also committed to disseminating the outcomes of the present plan to the rest of the school staff, teachers and school counselors, neighbouring schools, local and broader area through the school site, the local mass media, social media, personal blogs and presentations in seminars. They are especially committed to sharing their knowledge and disseminating best practices in the school, the city and in the country.
