Today the development of professional standards aimed at teachers of foreign languages and requirements applied to the level of professional competence are both greatly discussed. It is obvious that new approaches are needed in order to form professional courses which focus on enriching language and cultural awareness of school teachers of foreign languages. Following the changes of educational system in general and taking into account the growth of information and communication technologies and their impact on educational teacher-training courses, the digital environment should be considered as the most appropriate for the teachers’ professional development. Defining the learning style of the teachers and analysing the results of some questionnaires, the methodological approaches to the course have been chosen and described as a combination of the leaner-centered approach (for language teachers), communicative approach, Kolb’s learning styles model and digital learning. Some difficulties the language teachers usually face are vocabulary, fluency, in which non-native English teachers are in a disadvantage, grammar and listening and reading skills due to the lack of practice. To meet the language teachers’ expectations some actions such as supplementation the language teachers with appropriate amount of practice of receptive and productive skills, usage of discourse analysis to advance the teachers’ linguistic skills and enlarging their socio-cultural information with the help of texts for reading and listening are to be done. Moreover, the course includes elements of test tasks in the format of tasks of the unified state exam in English, as well as several international exams of the appropriate level. In the process of studying according to the course program, foreign language teachers increase the level of linguistic and cultural competence by working with texts containing material of a linguistic and cultural orientation. The results of final test and evaluation prove the effectiveness of the proposed and further described ideas.
