Modification of the educational environment in the process of teaching students a foreign language in college requires the development of fundamentally new approaches to the organization of educational work, which allows us to take into account the maximum number of various factors that have some influence on the process of learning a foreign language in college, its quality and results. At present, a very small number of scientific works are devoted to the study of changes in the educational environment in the process of teaching students a foreign language in college. At the same time, it becomes more and more obvious that the improvement of vocational education quality in the process of teaching a foreign language may be achieved only by activating all the educational factors, included in the educational environment, integrating them into a harmonious unity and appropriate modification. These circumstances determine the relevance of the research topic. The aim of the research in the article is to identify and determine the directions of the educational environment modification in the process of teaching students a foreign language in college. The article is prepared on the basis of the following methods: theoretical analysis and synthesis of domestic and foreign literature on the topic of the study, pedagogical observation and the method of analyzing the educational environment in the process of teaching students a foreign language in the College of Modern Technologies named after Hero of the Soviet Union M.F. Panov (Moscow). According to the results of the research, the article presents the directions of the educational environment modification in the process of teaching students a foreign language in college, the essence and methods of implementing the modified educational environment in accordance with various tasks during learning foreign languages. The theoretical significance of the research: the main methodological positions concerning the problem of the organization of the educational environment in the process of teaching a foreign language in the system of secondary vocational education (SVE) are analyzed and summarized. The practical significance of the research results: we identified the key factors affecting the emotional condition of students and interfering with productive educational activity in certain classrooms during learning foreign languages within the framework of skilled workers training system. Key directions of the educational environment modification in the process of teaching students a foreign language in college have been identified and determined. The main provisions and conclusions may be used in the process of academic staff training and upgrade training courses for college teachers.

It is shown that the stabilization of natural soils with ANT additives together with Portland cement causes a directed change in their properties and contributes to the development of new materials with an improved set of physical and mechanical characteristics for their use in the production of small building materials. The dependences of the compressive strength of samples from stabilized soils on the initial moisture content and the amount of additives introduced have been established. An optimal composition has been developed, characterized by improved compressive strength, water and frost resistance, recommended in the manufacture of building materials for low-rise construction.

In this study, nitrile butadiene rubbers (NBR-18) were modified by collagen hydrolysate (CH). Using FTIR spectroscopy, it was established that a new absorption band was found on the spectra of modified rubbers, corresponding to vibrations of the -C=N bond, which indicates the grafting of CH on to NBR-18 macromolecules. It was established that the CH in the amount of 3 phr leaded to an improvement in the complex of properties of rubber compounds, contributing to an increase in: conditional tensile strength by 41%; frost resistance (Kw) by 9% at -20 C, by 11% at -30 C.

The possibility and technical efficiency of FA-513 nanomodifier application in the compositions of greasers No.76 and No.4C have been confirmed. Optimal concentrations of FA-513 for greasers in the manufacture of microplastics have been established by the impregnation method. The obtained microplastics showed an increase in physical and mechanical characteristics by 12-25%.
