1. Two claims removed from this article
This post used to open by saying visual materials improve concept retention by up to 400%, and it had a section on supporting diverse learning styles that described infographics as essential support for visual learners. The first figure has no source we could find and is not one we should have repeated. The second rests on the idea that pupils have a learning style which teaching should be matched to — an idea that has been tested repeatedly and has not held up. Both are gone, and what replaces them is a smaller claim we can actually defend.
2. Dual coding is real; learning styles are not the same thing
It is worth separating two ideas that often get run together. Dual coding — the finding that verbal and visual information are processed through partly separate channels, so a diagram paired with a clear explanation can be easier to remember than either alone — has decent support behind it. The learning-styles claim, that a particular pupil is a visual learner and should be taught visually, does not. The practical difference matters: dual coding says pair the words with the picture for everyone, not sort the class into types and teach them differently.
3. When a diagram actually earns its place
Three cases, and outside them a paragraph is usually better. When the material is spatial — the parts of a cell, the layout of a system. When it is sequential — the water cycle, how a bill becomes law, the stages of a process, where the order is the content. And when it is comparative — two texts, two organisms, then and now, where the difference is the point. A sheet is a compression, and material that is mostly nuance loses the thing that made it worth teaching.
4. Set it as work more often than you hand it out
The most useful version of this in a classroom is the assignment, not the handout. A fixed frame forces the decisions that produce understanding — what the topic was actually about, which three facts support it, what gets cut — and those are exactly the decisions a pupil can skip when reading a finished sheet. It also produces something markable: the sheet shows you what they thought the point was.
5. One idea per sheet, and the source on it
The single most common fault in classroom material is a sheet that is really three sheets. Pick one idea, put the term being taught in the heading rather than a topic label, define the hard word on the sheet instead of assuming it, and keep the source and the date visible — partly because it is good practice, and partly because a dated sheet on a wall does not quietly become wrong three curriculum revisions later.
6. What this tool does, and what it does not
Paste the lesson notes or upload the chapter and a first draft comes back composed, with a structure chosen from the shape of the material. It does not know your subject: it arranges what you give it, so every fact on the sheet is still yours to check. There is no contrast checker and no alt-text field, so if you are producing material under an accessible-information standard, plan on checking that yourself. And the free plan is exactly one infographic, which is enough for a pupil's project and not enough for a set of thirty.
