1) Metacognition involves knowledge of one's own cognition and regulation of one's thinking processes. It is important for self-regulated learning.
2) Explicitly teaching metacognitive strategies like planning, monitoring, and evaluating can improve learning, especially when linked to specific academic domains.
3) Teachers should model metacognitive skills, consistently use metacognitive terminology, and provide opportunities for guided practice with feedback to help students develop metacognitive abilities. Online tools can support metacognitive activities.
