How can I narrate a demonstration so learners know what to notice?

Treat narration as a guide to attention, not a running commentary. Before recording or presenting, pick a small number of moments when a learner might miss a meaningful change, comparison, or decision. At each moment, connect three things: what you do, what the learner should look at, and why that detail matters. For example: “I’m placing the two pieces edge to edge. Notice whether the corners meet; that tells us if they’re aligned before we continue.”

Skip routine movements that are easy to follow and do not change what the learner needs to understand. If a movement is important because it is easy to miss, make it visible in your words: name the location, direction, contrast, or result to look for. Keep the cue short enough that learners can look at the demonstration rather than concentrate on a long explanation.

Review the demonstration one step at a time and ask: “What could a first-time viewer fail to see here?” Add a cue when the answer affects how they understand or repeat the step. Useful candidates include a small change in position, a visible difference between before and after, a choice between two options, or a result that confirms the step is complete.

Then remove cues that merely restate an obvious action. “Now I pick up the marker” usually adds little if the action is clear. “Notice the mark stops at the guide line” may be useful if that boundary is easy to overlook. You do not have to explain every possible detail; prioritize the detail that supports the next step. If viewers need to inspect something while you do another action, pause or hold the relevant view rather than piling more words onto the moment.

Use this outline for each important moment:

1. Action: “I’m [doing the visible action].”
2. Attention cue: “Look at [specific place, feature, or change].”
3. Meaning: “This matters because [brief connection to the next step or goal].”
4. Pause: Leave a moment for learners to inspect it; then continue or check what they noticed.

Worked example, assuming a demonstration of folding a paper strip: “I’m bringing the two short edges together. Look at the corners—do they meet? That alignment helps keep the fold straight. [Pause.] Now I’ll press along the crease.” The bracketed pause is a planning note, not spoken dialogue. If the demonstration is visible on screen, make sure the relevant detail is in view when you point it out; narration cannot direct attention to a feature learners cannot see.

Read the narration while watching the demonstration, and check whether each sentence has a clear job. A learner should be able to tell what to watch for and how it relates to the step—not just hear a stream of actions. If a sentence introduces several details at once, split it or keep only the detail needed right then. If a cue arrives before the feature is visible, move the cue or adjust the demonstration’s timing.

A useful final pass is to imagine watching with no prior knowledge: after each important action, ask what you would look at and whether the narration makes that clear. You can also ask a reviewer to describe the detail they noticed at a few key moments. Their response can reveal where your cue is unclear, but it is feedback on that review—not proof that every learner will notice the same thing.
