Language teaching refers to a process whereby a child gains communicative comprehension or fluency over a language. It involves practice by learners where facilitation is provided by a teacher. There are several methods of English language teaching and Communicative Language Teaching is one of them.Communicative Language Teaching is a method of language teaching which makes learners confident to communicate effectively by involving them in real communication.Here, Ms. Sudha is using Communicative Language Teaching as through this activity she is involving students in real communication rather than emphasizing writing skills and grammatical aspects of communication.The communicative approach is based on the principle that there is more learning from using language to communicate meaningfully than only from reading and listening as it aims to strengthen fluency, not accuracy.It promotes learners to encounter real-life situations and focuses on communication rather than grammatical structures. It emphasizes the functional use of language in the real context and focuses on linguistic competence plus an ability to use the language appropriately.Hence, it could be concluded that Ms. Sudha is using Communicative Language Teaching while giving this exercise to her students.Additional Information Grammar-Translation approach: In this approach, the learner first learns grammatical rules and then applies those rules in translating sentences from the target language in the mother tongue. It focuses on writing skills.Structural-oral-situational approach is based on the principle that language is primarily speech and therefore all structures and vocabulary must be practiced orally before moving on to reading and writing.Humanistic approach laid emphasis upon learners capacity for personal growth, freedom to choose their options for the future, and positive outlook.
