Teacher strategiesFor teachers

Adaptive teaching strategies

Worked examples first

Fully worked models before independent practice reduce load for novice learners without diluting demand.

Dual-code carefully

Words + relevant image supports learning; words + decorative image adds load. Every visual should earn its place.

Split the demand

Listen or write — not both at once. Read the passage first, then answer. Model the technique, then apply it.

Externalise the plan

Steps on the board, a checklist on the desk, a visual timeline. Free the working memory to do the thinking.

Automate the basics

Fluency in number bonds, letter formation and high-frequency words frees load for the harder ideas that build on them.

MisconceptionsFor teachers

Common misconceptions

  • "Rich task = deep learning." Rich tasks can overload novices; they suit learners with fluency in the basics.
  • "They should be able to hold it in their head." Working memory is a shared classroom resource — support it, don't test it.
  • "More scaffolding is less rigour." Scaffolding for novices removes noise so the thinking stays on the learning.

Processing Speed

Why this is relevant

Reducing load matters most when a child processes at their own pace — it prevents small delays becoming lost learning.
