The document discusses Communicative Language Teaching (CLT), an approach to teaching second languages that emphasizes using the language interactively to communicate and perform meaningful tasks. CLT focuses on interaction as both the means and goal of learning, considers communicative dimensions beyond just grammar structures, provides motivation for learners, and centers around their interests and needs. Some key benefits of this approach include its holistic view of language, ability to motivate learners, and relevance in a world where communication technologies are increasingly important.
