What is meant by the self-fulfilling prophecy and how does it apply to schooling?

 It means that when you make a prediction about yourself or someone else you can actually cause that prediction to come true. Eventually, you, or the person you’re making the expectation about, will act or conform to the expectations you set.

Now, this doesn’t all just happen by magic of course. But, essentially, when you form a bias or opinion in your head, your actions follow to confirm these suppositions. So, when you expect something to happen, you can unknowingly match your behavior to help make that situation unfold the way you predicted it would.
