The purpose of the study is to analyze the use of multimedia teaching technologies as a means of developing future linguists' professional foreign language competence and to substantiate the effectiveness of their use in professional training. A combination of modern methods of pedagogical research has been used to fulfil the set goals: theoretical methods, such as analysis, generalization, comparison, synthesis, and systematization of scientific, educational-methodological literature, to determine the current state of the research subject; empirical and diagnostic methods (observation, conversations, interviews, questionnaires, testing) to determine the effectiveness of using multimedia teaching aids and determine practical recommendations for their use; prognostic methods to ascertain and diagnose the level of professional foreign language competence in future linguists; pedagogical experiments to experimentally check the effectiveness of the application of multimedia teaching technologies (multimedia educational presentations) in the process of developing the professional foreign language competence of future linguists; and methods of mathematical statistics for quantitative and qualitative processing of research results and statistical verification of their objectivity using the Pearson X[superscript 2] test. The usefulness of multimedia technologies in the development of future linguists' foreign language competence has been substantiated. The practical aspects of creating multimedia presentations aimed at developing professional foreign language competence have been described. It has been proved that the use of multimedia educational presentations to create a foreign-language communicative environment during future linguists' professional training will increase the level of linguists' independent acquisition of educational information, as well as provide positive motivation for educational and future professional activities.
