Self-regulated learning refers to how students become masters of their own learning processes. Neither a mental ability nor a performance skill, self-regulation is instead the self-directive process through which learners transform their mental abilities into task-related skills in diverse areas of functioning, such as academia, sports, music, and health. This article will define self-regulated learning and describe the intellectual context in which the construct emerged, changes in researchers' emphasis over time as well as current emphases, methodological issues related to the construct, and directions for future research.
