“…CLIL science teacher is one of the fundamental and most numerous members of the team of professionals who ensure not only the acquisition of knowledge and the development of skills within the selected competencies but also the academic component of students' adaptation to new educational and organizational content and language learning conditions basing on the material of the discipline studied through a non-native language (Couto-Cantero & Bobadilla-Pérez, 2018;Kampen et al, 2018;Cimermanova, 2017;Urmeneta & Evnitskaya, 2014;Dalton-Puffer, 2011;Bicaku, 2011). As many researchers mark (Dimova, 2021;Hu & Gao, 2020;Ramankulov et al, 2020;Fernández-Barrera, 2019;Lo et al, 2018;Volchenkova et al, 2019;Macaro, Curle, Pun, An & Dearden, 2018;Rodríguez & Saray, 2018;Cimermanova, 2017;Bier, 2016;Kunioshi et al, 2015;Airey, 2012;Dalton-Puffer, 2011), English is most often used as an interim language or lingua franca in Russia and abroad. As noted in scientific reports (Airey, 2012;Arnándiz & Portolés, 2019;Bier, 2016;Hudson, 2009;Lo et al, 2018;McDougald, 2015), now teaching subjects through English as a non-native language is a prestigious category in many educational institutions.…”
