Working Memory- The Brain’s Sticky Note

Have you ever noticed a student who can decode every word on the page but by the end of the paragraph, they can't remember what they just read? It isn't always because they weren't paying attention. Sometimes, their working memory is overloaded.

Working memory is like your brain's sticky note.

It temporarily holds information while you're using it. When students are using most of that mental energy to decode words, figure out vocabulary, or untangle complex sentences, there's very little capacity left to make meaning. That's why reading can feel exhausting for struggling readers.

As teachers, we can reduce that cognitive load by:

-Preteaching key vocabulary

-Activating background knowledge

-Breaking complex texts into manageable chunks

-Stopping to check for understanding before students become overwhelmed

When we lighten the mental load, comprehension becomes much easier.

Lab Takeaway: Reading isn't just about effort—it's about cognitive capacity.

What have you found helps students stay mentally engaged with a challenging text without becoming overwhelmed?
