What is Content- and Language-Integrated Learning

Content- and language-integrated learning (CLIL) has been considered from the perspective of communicative competence development in the context of teaching professionally oriented English language in a technical university. The chapter outlines the main aspects underlying CLIL and describes the experience of teaching English to students majoring in Photonics in the format of “binary” classes involving two teachers: of English and of physics of lasers. Classes have been designed for 3rd- to 4th-year students who had mastered basic linguistic-cultural communicative competences and went on to continue using English in professionally oriented situations. This way of team teaching contributes to the development of communication skills in the students' professional area and facilitates the assimilation of curricular material by students.
