Managing Cognitive Load: Chunking (Workshop)

Working memory is small, and when a lesson overloads it, learning stops. Managing cognitive load means chunking content, reducing distractions, and building on what students already know, so their limited working memory is spent on the learning, not on coping.

Key takeaway

Working memory is limited; chunking content, cutting extraneous load, and building on prior knowledge keep students' mental effort on the learning instead of on coping.

Why it works

Cognitive load theory holds that working memory can handle only a few new elements at once, so instruction that presents too much at once, or adds extraneous load (confusing layouts, split attention, needless complexity), overwhelms learners. Chunking content into manageable pieces, removing extraneous load, and connecting to prior knowledge, which lets students handle more, are the levers for keeping load manageable.

The research: Sweller's cognitive load theory; research on working memory and instruction.

    The core activity: reduce the load in one lesson

    Teachers leave with one lesson chunked and stripped of extraneous load.

    Protect working memoryLearning stops when working memory overloads. Chunk the content, cut the clutter, and build on prior knowledge so effort goes to the learning.

    Facilitator notes

    Too much at once overwhelmsPresenting everything at once, or adding clutter and split attention, overloads working memory and stops learning. Chunk and simplify.

    Common questions

    What is cognitive load?
    The mental effort a task demands. Working memory is limited, so if a lesson demands too much at once, learning breaks down.
    How do I reduce it?
    Chunk content into smaller steps, remove extraneous load (clutter, split attention, needless complexity), and connect to prior knowledge, which lets students handle more.
    Doesn't reducing load mean dumbing it down?
    No. It means not overwhelming working memory while learning. The goal, deep understanding, stays; you just manage how much hits at once.
