Teach the Idea, Then Test Its Edges

Dania’s post makes an important distinction: two explanations can describe the same thing from different angles, but that doesn’t make every explanation equally sound. Sally’s question about language adds another layer: a change in wording may alter how an idea is expressed—or change its meaning.

A practical way to explore both is to ask someone to explain an idea in their own words, then try it on a familiar example and a contrasting case. What stays the same? What changes? This tests whether the idea transfers without treating one preferred phrase as the answer key. If the explanation breaks at the contrasting case, that gives us something specific to examine: the concept, the example, or the wording.

Repeating a definition can show recall. What kind of example helps you tell whether someone can use an idea, not just repeat it?
