Communicative Language Teaching (CLT) and Task Based in Language Teaching (TBLT) could be very different; however both have some features in common. In both methods is used the real situation, this feature helps to understand the language into our ordinary life. Students learn to use and practice in their daily life. To do this, dynamic and interactive activities open the mind of students to understand how language is used. For this reason, it is relevant that these activities will be creative, dynamic, and interactive. Also, students feel motivation to interact to others. Now we will analyze some differences of both methods. First, the main goal for CLT is to enable to students to communicate in target language, teacher, in this case, is a co-cooperator or facilitator of the learning. Whereas, in TBLT the main goal is to facilitate student´s language learning by engaging them in a variety of tasks that have a clear outcome. In other words, teacher´s role is to choose tasks, based on an analysis of students´ learning needs, that are appropriate to the level of students, and to create pre task and task follow up. Another significant difference is communicative competence, in CLT students can develop this component but in TBLT cannot. However, in TBLT students have the opportunity to use linguistic sources and these are more than linked aspects of language, but in CLT students cannot to do this. Finally, another difference is that in TBLT students can develop a variety of tasks and this involves to students into different styles of learning. Yet this does not happen in CLT. In conclusion, we can understand both methods from their perspectives, similitaries, differences, and applications. I think that both have positive and useful principles and these would be indispensable in my lesson plans.
