Regulation and motivation

The strategies with which individuals undertake to regulate and manage their learning are referred to as self-regulated learning (SRL). Motivation is important in self-regulated learning. The regulation necessitates some level of choice or intentional selection of approaches to assist the learner in achieving a goal or behavior. Self-regulation is referred to as self-generated ideas, emotions, and behaviors that are strategically organized to affect an individual's learning (Schunk & Zimmerman, 2007).
