Can You Spot The Lack Of Student Understanding?

How do you really tell if a student grasped the concept you’re trying to teach? With a test? Perhaps an essay? How about an interactive iPad app that reads the thoughts of the student and checks their pulse while examining their entire genome? Okay maybe the last one is not (yet) available, but it’s usually pretty tough to truly gauge student understanding.

That is, of course, unless you’re a clever math teacher. An example has been roaming around Pinterest lately where a teacher illustrates how he or she actually checked student understanding. Whether you understand the example below or not, it might take you a second to figure out just how little the student actually understood about the problem.

    That’s so awesome. I don’t even think the Math teacher could have created that herself if she tried.
