Is there a study that shows that scoring well on standardized tests does NOT reflect real learning? Perhaps there is, but... There is a lot rhetoric to the effect that "scoring well on tests just means you are good at taking tests", but (1) there is nothing wrong with getting good at taking tests, and (2) are we sure? Also, the process MAY or MAY not have harmed other students -- there is no reason to believe it would, that I can tell -- again, please respond if there is.
