Shaping and developing communication skills in non-linguistic faculties in higher education institutions remain relevant. Thus, the theoretical and methodological guidelines for training English professionally-oriented spoken production are among significant problems. Intending to overcome some related challenges, we conducted this study to investigate the efficiency of using presentational speeches based on authentic video materials. The main aim of the research was to analyze the problem from methodological and didactic perspectives and substantiate the theoretical and methodological principles of the professional training of monolingual students through the experimental verification of the effectiveness of the proposed methodology. To achieve the objectives of this study, in the first stage, we determined the efficiency of pedagogical conditions for developing the foreign language competence of students. Then we verified the efficiency of using presentational speeches in teaching Spoken Production. At the last stage, we analyzed the effectiveness of the proposed methods of forming and developing foreign language competence (Spoken Production) by using presentational speeches. The study sample included 45 students of the Sociology and Law Faculty in the National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute". We obtained the results that confirmed the efficiency of the presentational speech approach in teaching spoken production. Our study revealed that the presentational speech approach facilitates enhancement in the level of students' professional competence. These findings provide a good starting point for discussion and further research.
