Yeah, but you're making an assumption, who said it had to be multi-choice answers? Why can't someone build a NLP model to test essays of middle schoolers or high schoolers graders on American history? You can look for learning objectives in the essay and grade upon that. Why not build a tool with D3 or another modeling tool to teach chemistry? You could have them build compounds and then if they make a mistake, insert via a tool tip and tell them why. As they combine things, you read out what it is or test them based on the string they put in for the compound. You have to build it and name it correctly.
