The KWL strategy is a reading comprehension technique where students identify what they already Know (K), what they Want to learn (W), and what they have Learned (L) about a topic. A KWL chart is used to organize this information in a graphic organizer. It activates prior knowledge and sets a purpose for reading. Students fill out the K column with what they already know before reading, generate questions for the W column, and then fill in the L column with what they've learned after reading. The strategy helps students monitor their comprehension and is effective for learning from expository texts.
