At all times, in linguodidactics, the formation of a harmoniously developed personality, possessing all key competencies, has been topical. The implementation of this super-task to some extent was carried out in accordance with the time. The shift in educational paradigms has shown that the value of key competencies is a constant in didactics. And now the competence-based approach in education remains dominant. Despite the fact that a large amount of literature is devoted to the competence-based approach in general, the issue of ways of forming key competencies in private methods remains insufficiently illuminated. Еach subject has its own potential, which must be described. As we know, the educational material presented in the Model Curriculum needs scientific justification. In this regard, within the framework of this article, we make an attempt to consider the ways of forming the key competencies of students in the Russian language lessons in Kazakh schools.
