Metacognition is thinking about one's own thinking. It allows people to reflect on how they learn and what strategies work best for them. Using metacognitive strategies like mnemonics can help people learn more deeply. Mnemonics are meaningful words or phrases that help with memorization. Examples of mnemonics include using songs, acronyms, poems, and rhymes to represent and recall important information. Metacognitive strategies are most effective when they accurately reflect the learning task.
