The effectiveness of using L1 in second language classrooms: a controversial issue

This paper aims to uncover the hidden debate about the efficacy and inefficacy of using mother tongue in second language classroom. Teaching English as a second language is not an easy task to be undertaken. There are many approaches that postulate the optimal strategy for better teaching. As such, numerous researchers in the fields of language teaching and learning hold a belief that the use of L1 in L2 classrooms helps to facilitate learning. However, a significant number of researchers contend that the use of L1 in L2 classroom hinders learning and deprives learners from the exposure to the second language. As such, this paper tries to shed light on both views and to give evidence that using L1 in L2 classroom has a negative impact on L2 learners.
