The purpose of the research is to determine the effectiveness of the practical application of social media based on Web 2.0 technologies, aimed at developing students' English-speaking communicative competence. To implement the tasks and test the hypothesis put forward, the following scientific research methods were used: empirical (experimental learning using social media based on Web 2.0); diagnostic: observation, testing of students; statistical method - mathematical analysis of the data obtained during the experiment; descriptive: description and verbal recording of results. The results of the experimental study showed the correctness of the hypothesis put forward that the formation of English-speaking communicative competence among students will become more effective when creating a methodology using social media formed on technologies Web 2.0.

They were developed on the basis of the results of diagnostics of the level of formation of the English-speaking communicative competence in the process of teaching students in streaming mode. Future scientific searches are possible in the direction of theoretical substantiation and practical application of new social media based on Web 2.0 technology in other training courses and other (non-philological) specialties. This vector of research is especially necessary during distance learning as an alternative to the traditional educational process.
