What is a KWL chart, and how is it used in teaching science? Let's take a look first at what the 'KWL' stands for – it's an acronym for what students KNOW, WANT to know, and will LEARN during a lesson. KWL charts are graphic organizers that help students collect information before, during, and after a unit. Using a KWL graphic organizer supports the constructivist teaching model – the idea that deeper learning happens when students are actively involved in the learning process instead of passive recipients of new information.
When teachers use KWL charts to introduce new ideas and topics, they help students identify what they already know about the topic and better understand the objectives of the lesson. KWL charts can also be used by teachers to monitor student success. KWL charts help guide students through nonfiction texts, as they track their progress in three columns titled KNOW, WANT, and LEARNED. There are many different KWL chart format examples, and they can be used to teach a variety of topics and subject areas. I am going to share how I used a Picture-Thinking graphic organizer (one type of KWL chart) with the KnowAtom science curriculum to implement the Picture-Thinking reading strategy. This graphic organizer is even better than a KWL chart because students are working within a context to identify what they know, want to know, and what they've learned. I have been a teacher for about 20 years, and for the last five years of my teaching I have used the KnowAtom curriculum.
KWL Charts and Picture-Thinking Reading Comprehension
The picture-thinking routine is one of my favorite routines. I started using this in my classroom about two years ago, and it really made a huge difference in my students' engagement with nonfiction texts. When I made it part of my regular classroom routine, students started thinking in such different ways. I'm going to take you step-by-step through exactly how to implement this routine in your own classroom, using the Picture-Thinking graphic organizer to help.
What is a "picture thinker?" A picture thinker is someone who thinks more in pictures than in words or sounds. Incorporating the picture-thinking routine in your classroom will help not only those students who think "in pictures," it's a great way for all students to make strong connections between the context and new vocabulary words, concepts, and what they already know. Here's an example of a Picture-Thinking KWL graphic organizer I use in my classroom:
