Self-regulated learning (SRL) has become a pivotal construct in contemporary accounts of effective academic learning. I examine several areas of theory and empirical research, which are not prominently cited in educational psychology's research into SRL, that reveal new details of what SRL is and how students develop productive SRL. I interpret findings from these investigations to suggest that nondeliberative, knowledge-based elements are inherent in the processes of SRL, and in learning more generally. Several topics for future research are sketched based on an assumption that learning effectively by oneself will remain a goal of education and can be an especially revealing context in which to research SRL.
