There is a significant portion of academia entranced by novelty, the joy of forbidden or secret knowledge, and other such things. For these people, an idea is not valuable because it is true, or useful, or well-established by experience or science. In fact these are graded as points
against an idea. Boring.
Where these academics are most prominent is probably art. Opinionated opinion alert, but these are near the root of the reason why academic art has become utterly annihilated as a viable cultural source. The continual pursuit of novelty and reconstruction above all took them from anything beautiful, useful, or indeed even merely interesting into fields so far disconnected from anything beautiful, useful, or indeed even interesting that they are now irrelevant, despite their firm beliefs to the contrary.
Education... are pikers compared to them, honestly. But it does seem to be a consistent pattern that some education ideas are proposed and generate excitement precisely because they run contrary to experiences, the expectations of those doing it for years, precisely because they are different from established methods and curricula... and that is enough. Not because they can show better results. Not because of better outcomes. That they are different and heterodox is enough.
Unsurprisingly, when "better" is not part of the evaluation criteria, "better" is not what you get. And that's me being generous; at times "better" would also constitute a strike against the methodology... or at least, what you would consider "better".
Education is strangely bimodal. On the one hand you get savaged at the slightest suggestion that the curriculum is not perfect as is, and we have amazing stasis on what can be taught in most subjects, frozen around a hundred years ago. On the other hand you get crazies who think the solution to math is to start kindergartners out on college-level number theory (the original "New Math") or who want to redo education on the hippie drum circle model and teach math based on how it makes you feel (not thinking of anything in particular here, just a cynical pastiche of what I see out there lately). The one thing you can not do is incrementally improve the existing systems.
In the latter case it astonishes me how these people can zoom straight up to the Federal level sometimes, powered by the sheer academic excitement at a new theory, before anyone can hardly even formulate the thought of maybe running some tests on the new theory before pushing it out to millions of kids, and how this has happened over and over to greater and lesser degrees over the past 60-70 years.
