There's some really interesting data here, but I think one of the main conclusions they draw is wrong: Confused students are far more likely to actually understand. Looking at correct vs incorrect answers (almost 50/50 for 'confused' students), it seems like confused students are far more likely to guess. Edit: I realize after posting this that it's important to know the test format to figure out whether students understood or were guessing. The article unfortunately doesn't say much about the test format.
