Vocational School Complex in Giżycko was the applicant of the project "Modern methods of teaching are the way to improve the quality of education". The implementation period was from 1st June 2015 to 31st May 2016. Continuous improvement of the competences of teachers is one of the tasks of the school. Within the project, departure of three of our teachers for a one-week methodological and lingual course, implemented in an EU country – Great Britain, was planned. The main assumptions of the course were to improve: the knowledge on methods, techniques, strategies and teaching styles that promote creative and motivating way of learning English; knowledge of current changes in the educational system of Great Britain and development of tendencies in English language teaching; English language skills, exchange of ideas and experience as well as cooperation with teachers of secondary schools from other European countries. The objectives of the project were determined jointly by teachers and the headteacher, based on the needs of the school and its employees, so that the benefits of the trip apply not only to the participants, but also to the whole institution. The project helped to achieve the main goals which were to improve the quality of education in the Vocational School Complex in Giżycko in certain areas by improving the competence of teachers of English and to establish international cooperation. The project was attended by three teachers of English: Mrs Marta Tyszko, Miss Natalia Rommel and Mr Artur Wojnowski. The immediate effect of the training was a methodological and lingual strengthening of the powers of the English teachers in terms of knowledge and skills to apply effective modern teaching methods and techniques, effective ways to increase student motivation for learning and learning organizations, recognize different learning needs of the student, development of learners autonomy, use of Information Technology and improvement of communication skills. The teachers use their knowledge and skills in school practice. This increases the interest and motivation of students and contributes to their greater involvement and achieving better language skills.

Implementation of the project and the actions taken by the teachers after returning from the course, aiming to implement the acquired knowledge and skills, contributed to creation of the positive image of the school in the local environment.
