Metacognition is thinking about thinking, or planning, monitoring, and assessing personal awareness and understanding cognition and thought processes. Teaching Bloom's revised taxonomy can help students progress from lower- to higher-levels of thinking in the learning process. Teachers need to model how they think to help students develop metacognitive skills and abilities, including how to study to learn. These enables students to reflect upon how they think and build their self-efficacy in metacognitive knowledge and application. Numerous metacognitive strategies, including self-regulated learning strategies, and strategies transcending content domains, such as metacognitive reading approaches and self-questioning for learning are described.
