 The final qualifying paper of the bachelor Yang Xiao submitted for defense is devoted to a topic relevant not only for student work, but also for researchers at a more advanced level. The concept of mediation activity in the methodology of teaching foreign languages first appeared in the " Common European Framework of Reference for Languages: Learning, teaching, assessment " in 2001 and finally took shape in 2018 in the new edition [CEFR Companion Volume, 2018]. The content of mediation as a type of speech activity is being actively discussed and has not yet acquired final outlines. The author correctly approached this timely topic, disclosed it and developed it in the applied aspect.
The goals, objectives and results of the study meet the requirements of the St. Petersburg State University educational standard and the educational program in terms of mastering the established competencies.
The paper contains 56 pages, the list of references includes 25 titles in Russian and English. The structure of the main text of the work consists of an Introduction, two chapters with conclusions, Resume and significant Appendices containing linguistic methodological materials.

In the practical part of the work, the author gives a typology of tasks that has actual value for a modern teacher of a foreign language. 
In the first chapter "Theoretical aspects of the phenomenon of mediation in linguodidactics", the author examined in detail the concept of mediation in methodological science, types of mediation activity and the interpretation of this methodological category in CEFR.
