Cooperation with the Scientific Council "Ukrainian Language" makes it possible to coordinate the scientific and educational work of the Department in the context of the concept of development of the Ukrainian language as the state language and the language of education. The exchange of scientific and methodological experience with relevant departments of national universities contributes to raising the pedagogical skills of the Department's teachers, searching for innovative teaching methods, improving traditional technologies, and creating language communication strategies at the national and international levels.
