The differential success of second/foreign language learners suggests a need to examine in detail what strategies successful language learners employ. An indication is given of what these strategies might consist of and a list of several widely recognized good learner strategies is given. In addition to the need for research on this topic, it is suggested that teachers can already begin to help their less successful students improve their performance by paying more attention to learner strategies already seen as productive.
