sentences:  Content-based instruction
  
  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 very first day in class.
