What NYT seems to want you to think: Test taking is the best way to learn. Forget in depth studying techniques or figuring out how you yourself learn.
I had the opposite reaction. I figured the writer had been so indoctrinated into the view that "teaching to the test" was evil, bad, and wrong, that when a positive result popped related to testing, just that one point alone became the "news" hook of the story.
Hmm, in looking at her list of past articles, it appears the author mostly covers the medical beat. Perhaps it's a case of a "helpful" editor spicing up the story with a more controversial headline.
