The traditional KWL Chart can be used with any content area to start students thinking about what they KNOW about a topic, what they WANT TO KNOW about that topic, and what they have LEARNED at the end of the unit. It can be adapted for research by adding a column between the W and the L that requires students to think about HOW they will use resources to find the answers to their questions. A KWL Chart can be used as an assessment for learning because a teacher can quickly tell what students already know and understand about a topic. Below are several examples of KWL Charts.
