Content-based instruction (CBI) is a significant approach in language education (Brinton, Snow, & Wesche, 1989), designed to provide second-language learners instruction in content and language (hence it is also called content-based language teaching; CBLT). CBI is considered an empowering approach which encourages learners to learn a language by using it as a real means of communication from the first day in class.[1] The idea is to make them become independent learners so they can continue the learning process even outside the class.[1]
Historically, the word content has changed its meaning in second language teaching. Content used to refer to the methods of grammar-translation, audio-lingual methodology, and vocabulary or sound patterns in dialog form.
Recently, content is interpreted as the use of subject matter as a vehicle for second or foreign language teaching/learning (linguistic immersion).
