The KWL strategy is a three-phase graphic organizer used before, during, and after learning. It helps activate prior knowledge, guide inquiry, and promote reflection.
K – What I Know: Students brainstorm what they already know about a topic.
W – What I Want to Know: They generate questions or topics they are curious about.
L – What I Learned: After completing the lesson or reading, students summarize key takeaways.
The Three Phases of the KWL Strategy
Each phase corresponds to a stage in the learning process and supports better comprehension and retention.
1. Before Learning: Activate Prior Knowledge (K Phase)
Begin by prompting students with questions like:
- “What do you already know about this topic?”
- “Have you encountered this idea before?”
This primes students’ existing knowledge and prepares their minds for new input. Use a blank KWL chart to collect their ideas.
2. During Learning: Guide Curiosity (W Phase)
Encourage students to formulate questions as they explore headings, visuals, or lesson objectives. Good prompts include:
- “What do you hope to find out?”
- “What questions come to mind as you begin reading?”
This phase transforms learning into a student-driven inquiry process.
3. After Learning: Summarize and Reflect (L Phase)
Students review their K and W columns and write down what they’ve learned. This promotes retrieval practice and helps teachers identify knowledge gaps or misconceptions.
Why Use the KWL Learning Strategy?
The KWL learning strategy has multiple benefits that go beyond basic reading comprehension:
- Metacognitive awareness: Planning entries in the K and W columns prompts learners to set goals, monitor understanding, and adjust reading strategies in real time.
- Schema activation: Tapping into existing knowledge networks improves assimilation of new information and strengthens connections in long-term memory.
- Retrieval practice: Summarizing findings in the L column reinforces memory pathways, making recall more efficient and durable.
- Reflection and self-assessment: Comparing initial assumptions with learned outcomes promotes critical thinking and helps identify misconceptions for targeted review.
- Scaffolded learning: Dividing tasks into before, during, and after phases reduces cognitive overload and supports gradual skill development.
It’s also widely used in classrooms to support test preparation, group work, and independent research.
When to Use the KWL Strategy
The KWL strategy is most effective at key moments in the learning process, making it a versatile tool for both educators and learners.
1. At the Start of a Lesson or Unit
Use a KWL chart to activate prior knowledge before introducing new material. This helps students make connections between what they already know and what they’re about to learn, setting a strong foundation for comprehension.
2. During Reading or Exploration
The KWL chart isn’t just for the beginning and end—it can be used throughout the learning process. Encourage students to revisit and update the “Want to Know” and “Learned” sections as they read or research. This turns the chart into a live thinking tool, helping learners monitor their understanding and generate new questions in real time.
3. After a Lesson or Discussion
Wrap up a lesson by completing the “Learned” column. This reinforces retention through reflection and helps both teachers and students assess progress toward learning objectives. It’s also a great opportunity to correct misconceptions or highlight key takeaways.
4. For Ongoing Projects and Test Prep
Use the KWL strategy to track knowledge over time, especially in multi-day projects or review sessions. Students can build on their earlier entries, creating a record of how their understanding evolves.
How to Use a KWL Chart
The KWL chart isn’t just a reading tool. It’s a flexible strategy that can be applied across different stages of instruction and learning formats. If you’re new to the process, check out this step-by-step guide on how to make a KWL chart to get started quickly and effectively.
Here’s how educators, trainers, and learners can integrate the KWL strategy into various teaching and assessment scenarios:
1. Introducing a New Topic
Start any lesson by using a KWL chart to spark curiosity. Ask learners to record what they already know and what they’re curious about. This sets a clear direction for learning and encourages active engagement from the beginning.
2. Structured Research and Investigations
For independent projects or research assignments, the KWL chart offers a scaffolded way to plan inquiry. Learners can use the “Want to Know” column to outline research questions and use the “Learned” section to summarize findings, turning the chart into a personalized learning journal.
3. Interactive Note-Taking
Instead of traditional linear notes, students can use KWL charts to document evolving understanding. As they gather new information, they can revisit earlier questions in the W column and fill in their L column with accurate, personalized insights.
4. Blended and Flipped Learning
In digital or hybrid learning environments, KWL charts help identify comprehension gaps. Teachers can review submitted charts to determine who completed pre-class reading, what needs further clarification, and where misconceptions might exist.
5. Study and Review Tool
When preparing for a quiz or exam, students can use a KWL chart to organize their knowledge. First, they list what they already understand, then generate questions by skimming course material. After reviewing or studying, they complete the L column to reinforce new knowledge.
6. Formative Assessment
KWL charts serve as a low-stakes, high-insight assessment method. Teachers can analyze the quality of responses in each column to evaluate participation, conceptual understanding, and progress. Both qualitative reflections and quantitative entries provide valuable feedback.
KWL Strategy for Reading
The KWL strategy is especially effective when used to support reading comprehension. It turns passive reading into an active, goal-oriented process by helping readers make sense of texts before, during, and after reading.
Before Reading: Activate Prior Knowledge
Start by filling in the “K” (Know) column. Ask readers what they already know about the topic—this could include facts, opinions, or even misconceptions. Then, use the “W” (Want to Know) column to list questions or areas of curiosity. This primes the brain to seek answers and stay focused while reading.
During Reading: Monitor Understanding
As readers progress, they revisit the W column to see which questions are being answered. Encourage them to take notes or highlight answers they find. This step promotes active engagement and helps track how understanding evolves.
After Reading: Reflect and Summarize
Finally, in the “L” (Learned) column, readers summarize what they’ve learned from the text. This reflection stage helps solidify key takeaways, identify remaining questions, and make connections to prior knowledge.
Tip: For longer texts, the KWL chart can be used across chapters or sections to keep comprehension focused and continuous.
Whether you’re reading nonfiction, academic texts, or even literary passages, the KWL chart strategy for reading helps improve focus, retention, and comprehension at every stage.
KWL Strategy for Test Taking
The KWL test-taking strategy helps students organize their review process effectively.
- In the K column, they list what they already know about the test topic.
- The W column becomes a space to ask questions about confusing areas or anticipated test questions.
- The L column is used post-review to summarize learned concepts or clarify misunderstandings.
This approach encourages active revision and helps identify knowledge gaps before assessments.
Subject-Based KWL Chart Examples
1. KWL Chart for Science
