Successful language learners cannot be distinguished by a single set of learning activities but rather
they are identified through their capacity to understand and develop a personal set of effective learning
strategies. The subjects of this study have developed or tried to develop their own set of effective learning
strategies. In fact, those subjects practicing a variety of learning activities on their own have successfully
gained higher scores on the TOEIC exams. Students could benefit if EFL instructors share ideas for effec-
tive language learning activities: first, students will choose some of them and then they will develop their
own activities later.
