What is the purpose of using the K-W-L technique in reading instruction?

The K-W-L technique, which stands for "Know, Want to know, Learned," is designed primarily to help students engage with a text by facilitating summarization and reflection on what they have learned. In this strategy, learners are first prompted to list what they already know about a topic (the K), followed by what they want to learn (the W) before they read. After reading, students can reflect on what they have learned (the L). This process encourages active engagement with the material, promotes comprehension, and helps students organize their thoughts. By summarizing and reflecting, students deepen their understanding and retention of the content, making it a valuable tool in reading instruction.
