Using a KWL chart to strengthen reading comprehension

A KWL chart is one of the simplest graphic organisers a teacher can hand out, yet it transforms a passive reading session into an active investigation. The three columns stand for What I Know, What I Want to know, and What I Learned, and they guide a reader from prior knowledge through curiosity to reflection. Because the framework is visual and almost conversational, it works across primary, secondary, and adult learning contexts, including TAFE preparation and university bridging programs.

For Australian classrooms, where learners range from Year 3 readers tackling their first chapter books to adult English-language students sitting the IELTS, the chart offers a shared language for thinking. It also aligns comfortably with the literacy demands of the Australian Curriculum, particularly the comprehension strategies outlined in the English strand. When students see the same scaffold in a Brisbane primary school and a Melbourne adult-migrant class, the cognitive moves remain identical: predict, monitor, summarise.

What makes the KWL chart especially useful is its honesty. The middle column openly admits what the reader does not yet understand, and that gap is precisely where comprehension grows. The chart turns a textbook or news article into a conversation with the text, prompting readers to mark, question, and ultimately consolidate what they have taken away from the page.

What a KWL chart actually does

The KWL strategy was popularised by American educator Donna Ogle in the 1980s, but its principles belong to any classroom that values metacognition. The first column catalogues what the reader already believes about a topic. Filling it in forces students to retrieve information from long-term memory, surface assumptions, and notice where their knowledge is thin. Teachers can use this column to diagnose misconceptions before reading begins, which is far more efficient than untangling misunderstandings after a lesson.

The second column, often called the W, is where curiosity lives. A reader writes down specific questions sparked by the topic, the heading, or a quick scan of images and subheadings. Strong questions are open-ended and content-specific, such as "How do Indigenous firestick practices reduce bushfire risk?" or "Why does the Reserve Bank raise interest rates?" Because the questions are personalised, students arrive at the text with purpose, scanning for answers rather than drifting through paragraphs.

The third column, traditionally completed after reading, captures the new information the reader absorbed, addresses earlier questions, and records lingering uncertainties. This last move is often missed in simplified versions of the chart. Recording what is still confusing is just as valuable as noting what is now clear, because it directs follow-up research, discussion, and re-reading.

Activating background knowledge before reading

The K column works best when treated as a quick brainstorm rather than a polished essay. A teacher might set a two-minute timer and ask students to jot anything they associate with the topic, including half-formed hunches and cultural references. In a Sydney Year 7 class studying a unit on the Great Barrier Reef, for instance, students might list "climate change," "tourism," and "crown-of-thorns starfish" before opening the article. In a Perth adult literacy group, learners preparing for the citizenship test might write "parliament," "referendum," and "Welcome to Country" before tackling a civics passage.

This pre-reading step is particularly important for English-language learners who may carry strong background knowledge in their first language but struggle to access it in English. A simple bilingual prompt, such as asking students to think in their strongest language first and then translate key terms, helps them find mental hooks for the new vocabulary. Teachers can reinforce this by pre-teaching five to seven content words, drawing examples from local contexts such as AFL grand final week or school holiday programmes.

Activating prior knowledge also reduces the cognitive load of decoding unfamiliar text. When a student already recognises the word "drought" from news reports about Murray-Darling Basin allocations, decoding the rest of the sentence becomes easier. The K column, then, is not a filler activity. It is the foundation that lets the rest of the lesson work.

Tracking new learning during reading

The L column is the live notebook of the reading experience. Rather than waiting until the end to summarise, students record insights, surprising facts, and answers to their W questions in real time. Annotating in the moment keeps attention sharp and gives the reader permission to react emotionally to the text, which strengthens memory encoding.

A practical method is to pause at the end of each section or subheading and ask students to add a single entry to the L column. In a unit on Australia's colonial history, a student might add that the Eureka Stockade took place in Ballarat in 1854, or that the Australian colonies federated in 1901. These small, frequent deposits of information are easier to retrieve later than a long summary written after the reading is finished. They also produce a more honest record, because the reader is capturing the journey of understanding rather than a reconstructed narrative.

For digital readers, the L column can be mirrored with a simple note-taking app or even the comments feature in a school-licensed PDF viewer. Teachers running online reading programs can use a shared document where students append one sentence at a time, creating a collective running summary. This is especially useful for news-based comprehension, where the online reading strategies review highlights the need for real-time annotation when articles update throughout the day.

Filling the want-to-know gap after reading

Once the reading is complete, the L column should be reviewed and refined. Many teachers find it useful to revisit the original W column and tick off questions that have been answered, rewrite questions that have shifted, and flag any that remain unresolved. A class working through a neighbourhood policing study, for example, might begin by asking whether visible patrols reduce crime, and end by realising that the relationship is more complicated than a simple yes or no.

The post-reading stage is also where teachers can push for higher-order thinking. Students can be asked to rank their new learning by surprise value, identify which prior knowledge from the K column was correct or incorrect, and write a one-sentence takeaway for a partner. For senior students preparing for NAPLAN reading or the GAT in Victoria, this synthesis step mimics the kinds of comparison and inference questions they will meet in standardised tests.

A useful extension is to convert the completed KWL chart into a short piece of writing. A Year 9 student might turn it into a paragraph for a class blog, while an adult learner could use it as a speaking frame for an oral presentation. The chart, in other words, is not the destination. It is the launch pad for a more permanent expression of understanding.

Tailoring KWL charts for Australian classrooms

Australia's education landscape is unusually diverse, with state and territory systems each interpreting the Australian Curriculum slightly differently, and with significant variation between metropolitan, regional, and remote schools. A KWL chart adapts easily to this variation. In a Darwin remote classroom with intermittent internet, the chart can be drawn in a workbook and revisited over several days. In a high-tech Adelaide secondary school, the same chart can live inside a learning management system like Canvas or Compass.

For Aboriginal and Torres Strait Islander students, the KWL chart can be extended with a fourth column acknowledging Country, community, and cultural protocols connected to the topic. A reading about the Daintree rainforest, for instance, can begin with knowledge shared by Kuku Yalanji elders and then move into Western scientific accounts. This approach respects the principle that knowledge is not neutral and helps all students see multiple perspectives.

Adult learners benefit from a slightly different emphasis. Many are balancing study with work and family, so the W column can include practical questions such as "How long will this unit take?" or "Which vocabulary words appear in the workplace?" The State Library of Victoria and public libraries across Brisbane, Hobart, and Canberra run free literacy workshops where the KWL chart can be introduced alongside book club routines, making the strategy portable across formal and informal learning settings.

Pairing the KWL with digital practice

While a paper chart is perfectly effective, digital practice reinforces the same habits in a format that mirrors how many Australians read every day. Online reading platforms can prompt students to record their K and W entries before unlocking an article, then guide them through the L stage with built-in vocabulary checks and short reflective questions. Immediate feedback on comprehension questions turns the chart from a static document into a live feedback loop.

For teachers managing mixed-ability classes, digital reports make it easier to spot which students are filling the W column with surface-level questions and which are pushing into analysis. Adjusting instruction then becomes faster and more precise. A simple next step for any educator is to explore the broader collection of lessons, exercises, and progress-tracking tools available on the reading comprehension platform and consider how a KWL scaffold might slot into an existing unit.

Bring the KWL chart into your next lesson, model it on the board with a topic your students genuinely care about, and let the questions drive comprehension forward. Whether you teach a Year 4 class in Geelong, run a Saturday reading circle in Fremantle, or support adult learners in western Sydney, the chart is ready to use with no special resources beyond a sheet of paper and a willingness to be curious.
