The issue is that "learning styles" as a phrase is overloaded. If you've read about the debunked theory of learning styles, and you hear someone use that phrase, you think they're talking about that, and they just haven't read the same article (headlines) you did. But, the phrase makes sense when used for something else: simply a description of what methodology an individual uses to study. The best solution would be for people to read critically and determine what the author intends by that phrase. I mean, that would be the solution in theory, but it's never going to happen. So, the more realistic solution is to just never use that phrase unless you're repeating that it's been debunked.
