Content-based instruction is a teaching method aimed to master both language and content.
CBI lies on the belief that learning content and language together keeps students interested and motivated. It’s true that students learn better when learning a language through a subject they are passionate about.
Hence, learning a language in contemporary classrooms where teaching is limited to grammar and reading comprehension may not be appropriate.
In a CBI class, content is very important because it determines what language is worked on.
