Communicative language teaching (CLT), or the communicative approach, is an approach to language teaching that emphasizes interaction as both the means and the ultimate goal of study.
Language learners in environments utilizing CLT techniques, learn and practice the target language through the interaction with one another and the instructor, the study of “authentic texts” (those written in the target language for purposes other than language learning), and through the use of the language both in class and outside of class.
Learners converse about personal experiences with partners, and instructors teach topics outside of the realm of traditional grammar, in order to promote language skills in all types of situations. This method also claims to encourage learners to incorporate their personal experiences into their language learning environment, and to focus on the learning experience in addition to the learning of the target language.
According to CLT, the goal of language education is the ability to communicate in the target language. This is in contrast to previous views in which grammatical competence was commonly given top priority. CLT also focuses on the teacher being a facilitator, rather than an instructor. Furthermore, the approach is a non-methodical system that does not use a textbook series to teach the target language, but rather works on developing sound oral/verbal skills prior to reading and writing.
