Avoid Split Attention

The strategy, as published

Exactly as it appears on the card

Part of Managing Cognitive Load in 05 Explanations & Modelling, where it sits alongside its neighbouring strategies, the infographic and the thinking for the whole area.

Why you might use it

The problem it may help with

Put the labels in one place and the diagram in another and pupils must search between them, holding fragments in mind while their eyes travel. Sweller calls this split attention, and the searching spends exactly the working memory the explanation needs.

Integrating labels directly into the image removes the search. Nothing about the content changes; only the cost of reading it.

What it might look like

One version of it, in a classroom

Teaching the water cycle, a teacher shows the diagram unlabelled and adds each label live with an annotation tool, placing the word on the part it names while explaining that stage. The class never has to match a numbered key to the picture.

Try it

A way to begin

Find one resource you use where the key or captions sit apart from the image, and move the words onto the image itself.

What to notice

Reading what happens

• Whether the which-bit-is-that questions disappear.
• How pupils label their own diagrams afterwards, and whether the integrated layout gets copied.

Things to think about

Before and while you use it

• Building the labels live does two jobs at once: it integrates the information and it paces the reveal to your explanation.
• When you cannot edit a printed resource, annotating it under a visualiser achieves the same integration.

Where this connects

• 📍 Keep Words Near Images Mayer’s spatial contiguity: place words near the images they describe. Labels sit beside the diagram, not in a separate list. Use slide design to keep related information together. 05 Explanations & Modelling · Multimedia & Dual Coding
• ➡️ Signal What Matters Mayer’s signalling: bold, arrows and highlights direct attention to what matters. Use annotation tools to signal live during the explanation. Without it, learners search alone. 05 Explanations & Modelling · Managing Cognitive Load
• 🔇 Say It or Show It, Not Both Sweller’s redundancy effect: narrating text on screen forces double processing. Say it or show it, not both. Use the B or W key to blank the slide while you talk through the idea. 05 Explanations & Modelling · Managing Cognitive Load
• 📷 The Visualiser as Stage A visualiser turns any desk into a modelling stage. Show handwriting, annotate text, build diagrams under the camera. The EEF found this among the most promising classroom technology. 05 Explanations & Modelling · Modelling & Worked Examples

The wider thinking

Where the evidence sits

Split attention comes from Sweller's cognitive load research; Mayer's spatial contiguity principle is the same insight arrived at through multimedia learning. The card’s attribution stands as published: Sweller.
