7. Content-Based Instruction CBI
a. The Definition of Content-Based Instruction CBI
Content-Based Instruction or CBI is considered as the most appropriate method used in teaching English for vocational high school since it considers
content as the starting point. According to Brinton in Nunan 2003:201, CBI refers to the language teaching through exposure to the content that is
interesting and relevant to learners. She also stated that content serves several purposes such as providing a rich context for the language classroom,
allowing the teacher to present and explain specific language features, and providing the comprehensible input.
Richards 2006:28 defines CBI as the information or subject matter that students learn or communicate through language rather than the language
used to convey it. Added to this, Krahnke in Richards 2006:27 defines CBI as the teaching of content or information in the language with little or no
direct effort to teach the language itself separately from content being taught.
