Metacognition is thinking about thinking—awareness of what you know, what you don't know, how you learn, and what strategies work for you. A metacognitive student notices "I don't understand this" or "I'm trying a strategy that's not working, I need a different approach." Metacognitive awareness builds independence and problem-solving.
Research strongly links metacognitive development with improved academic outcomes, particularly in literacy and mathematics. It's not something to add to already-full curriculum—it's foundational to effective learning.
