Content-Based Instruction (CBI) challenges in Turkey: Voices of high school students

CBI is gaining popularity all over the world and in Turkey. We hear more about it as the International Baccalaureate are becoming popular. There is void in literature about CBI and high school as most studies are done in tertiary context. The current study is mixed-method research with the participants from high schools in Turkey. The findings of the current study have shown that language and content integration provide high school students with a clear and relevant learning background. When language is a key to substantive interactions, events have real intent and involve a sincere exchange of meaning. The themed learning helps students to strengthen their reading and writing skills as they can create schemes during the course and can adapt existing schemes to new learning situations. CBI also found to be a source of motivation for learners to use the language in an authentic context.
