Learner strategies are of crucial importance in ESL/EFL learning and teaching. The importance lies to the fact that learners are encouraged to become autonomous language learners by self-evaluating their learning and self-directing the process of language development. More effective learners differ from less effective ones in that they use more strategies and in greater variety. Research shows that learner strategies can be taught and can facilitate language learning if a number of factors, such as the explicitness of the strategy instruction, the individual differences of the learners, the appropriateness of the teaching materials, the teacher training on the strategy instruction etc. should be taken into consideration.
