Introduction. The article addresses the authors’ approach to solving the problem of formation of professional communication abilities during information and digital training of future vocational education teachers. Aim. To examine the concept of “professional communication abilities” in terms of computer modelling readiness; to present a pedagogical technique for the formation of professional communication abilities in the context of completing the transdisciplinary module “Computer modelling” and industrial and pedagogical practice. Methods. The following approaches were used as the methodological basis of the study: modular competence-based approach (general principles of the formation of the professional communication abilities during the information and digital training); logical and informational approach (for the correct display of the conceptual apparatus of research and the evaluation of the possibilities for using logical principles and operations for processing and presenting data and information); trans professional approach (reveals the features of the content construction of information and digital training, within which the formation of the professional communication abilities is carried out). Among the main research methods are: analysis of scientific publications, study of the students’ training experience at the Department of Engineering and Vocational Training in Mechanical Engineering and Metallurgy of RSVPU. Results. The use of the developed pedagogical technique for the formation of the professional communication abilities allows for the establishment of more effective communication, a change in the communication style, and contributes to the development of professional and personal qualities of students. Scientific novelty. The conceptual basis of the presented pedagogical technique for the formation of professional communication abilities can be used to develop communication skills during the training of vocational education teachers.
