Comprehension is more than decoding
Once a student can decode words, understanding them is a separate challenge. A student can read every word aloud correctly and still not grasp the meaning — because comprehension depends on more than sounding out words.
Vocabulary and knowledge
Reading comprehension depends on two things no strategy can replace: vocabulary and background knowledge. You understand a text about baseball far better if you already know baseball. This is why the best long-term comprehension strategy is building knowledge broadly — a rich curriculum in science, history and the arts is itself reading instruction.
Active reading strategies
Strong readers work while they read. Research-backed strategies include:
- Preview — skim headings and structure before diving in
- Question — ask what the author is claiming and why
- Summarize — put each section in your own words
- Monitor — notice when you're lost, and reread
- Connect — link the text to what you already know
Reading by subject
Different texts need different approaches: textbooks reward previewing headings and turning them into questions; literature rewards attention to character and theme; primary sources and dense nonfiction reward slow, careful rereading. Good readers shift gears to fit the text.
How families can help
- Keep reading aloud and talking about books at every age
- Build vocabulary and knowledge through conversation and experiences
- Ask 'what do you think will happen?' and 'why?'
- Encourage rereading when something doesn't make sense

Frequently asked questions
- Why can my child read the words but not understand? Decoding and comprehension are different skills. Understanding depends on vocabulary and background knowledge, plus active reading strategies like questioning and summarizing.
- What's the best way to improve comprehension? Build knowledge and vocabulary broadly, and read actively — preview, question, summarize and reread when lost. Wide reading across subjects helps most.
- Does reading speed matter? Understanding matters far more than speed. Good readers slow down for hard material and reread when they lose the thread.
- How does background knowledge affect reading? Enormously. You understand and remember a text far better when you already know something about the topic, which is why broad knowledge is itself reading instruction.
- Should students read the same way for every subject? No. Textbooks reward previewing and questioning, literature rewards attention to character and theme, and dense sources reward slow rereading.
