Metacognition involves thinking about one's own cognitive processes and thinking style. It is essential for effective learning as it allows people to self-monitor and adapt their learning strategies. The advantages of metacognition include developing independent, life-long learners who can control their own learning. Teachers can foster metacognition in students by using multiple representations of concepts and activities to help students think about how they learn best. The goal of metacognition is to help students set learning goals and adapt their strategies based on self-monitoring of progress towards goals.
