The primary objective of this paper is to study the role of mediation in second language learning and to identify some concepts or phrases represented by the mediative process. This study has opted to discuss the three most influential phases related to the emergence of learning strategies and the attainment of self-regulatory capacities. The first phase, reflection, is essential for the learner's active engagement to take place in learning, focusing primarily on conscious awareness. The second phase, practice, concentrates on the development of and commitment to the learner's specific goals. The third phase, control, highlights the importance of persistence in order for active creation of learning strategies to occur internally. These phases are interrelated but have diverse learning activities. One benefit of this study is to help in the transformation from other-assisted to self-assisted language learning.
