The use of informational communicative technologies has enabled instant access to remoted module informational resources, synchronous (asynchronous) communication between subjects of the educational process. It has also provided new opportunities for testing, administration, and cooperation. The experimental usage of the author's methodology was implemented into the teaching process of the subject “Foreign language” based on the intercultural educational environment as a set of immersion, virtual, interactive, and discourse educational environments. The analysis of the obtained results and objective consideration of the dynamics of the changes in the formation of communicative competence of future officers have been done through the integrated test (targeted monitoring, a set of adapted tests application, an online survey, a questionnaire, case study, situational modelling, individual and group interviews) and methods of mathematical statistics. The conducted study has proved the efficiency of the author’s methodology implementation based on the intercultural educational environment of higher military education establishments. The proposed methodology can be successfully used in the process of foreign language training of various specialists because its main strategic orientation is to form communicative competence and abilities for intercultural communication among students (cadets).
