The learning styles that are not there

Ask a room of teachers whether some pupils are visual learners and others learn by listening, and nearly all of them will say yes. Ask for the evidence and the room goes quiet, which is not a criticism of teachers. The idea is taught on teacher training courses, printed in textbooks and repeated by people with no reason to doubt it.

The claim can be stated precisely enough to test. It is not that people have preferences, which they obviously do, nor that some material suits pictures better than words, which is also obvious. It is that matching the teaching method to the learner's preferred style improves how much that learner retains. That is the claim, and it is the one that has repeatedly failed.

The test required is straightforward. Identify learners' preferred styles, teach the same material to some in their preferred mode and some in another, then test everybody. Dozens of studies have done this, and the result is consistent: people learn about the same amount either way. What does predict performance is whether the mode suits the material, which is a statement about the subject rather than about the learner. Nobody learns the shape of a coastline by listening to a description of it.

Why the idea survives is more interesting than why it is wrong. It is flattering, because being told you have a style explains past difficulty without blame. It is actionable, which makes it attractive to anybody selling training. And it has a grain of truth inside it: learners do differ, enormously, in prior knowledge, in vocabulary, in confidence and in how much they already care about the subject, and those differences are real and large. The style label gives a name to a genuine observation and attaches it to the wrong cause.

The practical cost is not that lessons are delivered in the wrong mode. It is the time and money spent on diagnosing styles, and worse, the effect of telling a child that they are a particular kind of learner, which is an invitation to avoid whatever has been labelled as not theirs.
