Withhold the answers from yourself. We’ve heard a lot lately about the benefits of experiencing and overcoming failure. One way to get these benefits is to set things up so that you’re sure to fail that people who try solving math problems in this way don’t come up with the right answer—but they do generate a lot of ideas about the nature of the problems and about what potential solutions would look like, leading them to perform better on such problems in the future. This “productive failure,” and you can implement it in your own learning by allowing yourself to struggle with a problem for a while before seeking help or information.
Expose yourself to confusing material.
