Course slides that do not put learners to sleep

Most learners have sat through a lesson where the instructor reads slide after slide of bullet points aloud. The words on the screen match the words in their ears, the layout never changes and, within a few minutes, attention drifts elsewhere. Online, drifting is even easier. Another tab is always one click away.

Slides are not the problem. Used well, they help learners see structure, follow a process and remember what matters. The problem is slides built as speaker notes rather than as teaching tools. With a handful of design habits, your course slides can keep learners watching and help them understand, without any special design skills.

Why slides send learners to sleep

The same few problems appear again and again:

• Walls of text. Learners try to read and listen at once, and do neither well.
• Reading the slide aloud. If the voice repeats the screen, one of them is wasted.
• Too many points per slide. Seven bullets means seven ideas competing for attention.
• Identical layouts. Slide after slide of heading plus bullets gives the eye no reason to look.
• Decoration without purpose. Clip art, animations and busy backgrounds that add noise but no meaning.

One idea per slide, with a headline that says it

The most useful single change is to put one idea on each slide and state that idea as a full sentence at the top. A topic label such as “Venue Costs” tells learners what the slide is about. A sentence tells them what to understand.

Imagine a hypothetical membership for independent event planners, run by a planner named Benedikt. Here is one slide from his budgeting course, before and after:

Before: Headline “Venue Costs”, followed by seven bullet points covering rental fees, deposits, minimum spends, service charges, overtime, cleaning fees and cancellation terms.

After: Headline “The venue is usually your biggest cost, so book it first.” Beneath it, a simple bar showing a sample event budget with the venue portion highlighted.

The seven cost types did not disappear. They moved to three further slides, each with its own headline, and to a written checklist beneath the lesson. Learners now see one clear point at a time, and Benedikt explains the detail in his narration instead of reading it.

Let the slide show what your voice cannot

Your voice is good at explaining, giving examples and adding warmth. Slides are good at showing things that are hard to describe aloud. Use each for its strength:

• Sequences. A process shown as numbered boxes connected by arrows.
• Comparisons. Two options side by side, with the difference highlighted.
• Real examples. A photo of the actual document, form, product or finished work, not a description of it.
• Structure. A simple map of the lesson or module, with the current step highlighted.
• Key numbers or phrases. One figure or short phrase, large on the screen, while you explain what it means.

A useful test: if the slide makes sense without your narration and your narration makes sense without the slide, they are duplicating each other. The best slides and narration need each other.

Design basics that keep slides readable

You do not need to be a designer, just consistent and restrained:

• Large text. Many learners watch on phones or small laptops. If text is hard to read on a phone, it is too small.
• Strong contrast. Dark text on a light background, or the reverse, with no text over busy photos. The same principles behind color and contrast for readable pages apply to slides.
• One or two fonts, used the same way throughout.
• A simple template with two or three layouts you reuse: a headline with a visual, a headline with a short list, and a full-screen image or phrase.
• Space. Empty space around a point makes it easier to see. Resist filling every corner.

Build in change and interaction

Attention follows change. When the screen stays the same for minutes at a time, learners stop looking at it. Change slides often, even if that means more of them; twenty slides with one point each are easier to watch than six crowded ones. Reveal steps one at a time rather than showing a whole process at once.

Add moments that ask learners to do something. A slide that says “Pause here and write down your three biggest costs from your last event” turns watching into thinking. A recap slide at the end of each section, with the two or three headlines from that section, helps learners check they have followed along.

A worked example: rewriting a slide sequence

Benedikt's original lesson on contingency funds had three dense slides. His rewritten version has seven:

1. “Every event budget needs a contingency fund.” A photo of a rained-out outdoor reception.
2. “Unexpected costs are normal, not a sign you planned badly.” Three short examples, revealed one at a time.
3. “Set your contingency before you commit to anything.” A timeline with the step highlighted.
4. “Size it to the risk.” A comparison of an indoor event and an outdoor one.
5. “Pause and try it.” Learners set a contingency for their next event.
6. “Tell the client what it is for.” A sample line from a client budget.
7. Recap: the five headlines above, together on one slide.

Improving your course slides

1. Open one lesson's slides and count the ideas on each. Split any slide with more than one.
2. Rewrite every slide headline as a sentence that states the point.
3. Replace at least three text-heavy slides with a visual: a sequence, a comparison or a real example.
4. Check the text is readable on a phone screen.
5. Add one pause-and-try slide and one recap slide per section.
6. Offer the key points as notes beneath the video, laid out as described in designing a lesson page that helps people learn.
7. Rerecord the narration so it explains the slides rather than reading them.
