Metacognition refers to knowing what one knows and doesn't know, and involves self-monitoring of understanding. Self-regulation means students monitor their own comprehension without teacher help. The teacher's metacognitive practices can promote student self-regulation if done effectively. Self-regulation involves actively searching for patterns to resolve contradictions and involves exploration, invention, and application. Instructional strategies that teachers can use include stating objectives, providing feedback, and teaching content in multiple contexts to promote student metacognition and self-regulation.
