The present stage of society development demands drastic changes in the educational system. The conceptual basis for such reorganization could be provided by the new knowledge paradigm of discipline synthesis. For professional training at the tertiary level the most promising idea seems to be disciplines integration, in particular, that of the major subjects and foreign language instruction. In this case the Content and Language Integrated Learning (CLIL) naturally suggests itself. Though it is not soon to be widely introduced due to the lack of specialists, it can effectively be used alongside English for Specific Purposes (ESP) and English as a Medium of Instruction (EMI) when a language teacher works with students of different technical major subjects and language levels.
