Clearly we are not always accurate in predicting students' learning. Of equal concern, though, is the certainty of our belief that students are learning.

People (and that includes professors) tend to be more confident than correct when assessing the accuracy of their beliefs and judgments. On the bright side, there are ways of managing this overconfidence bias.
