What are your students' beliefs about success in school?
Have you asked? If not, don't fret. What do their actions tell you?
Beliefs are only as valid as they are acted upon. The implications of a true belief are a call to action. When the action suggests something different, then the belief is either poorly communicated or not truly a belief.
Do your students "walk their talk?"
If not, they should consider either changing the belief or changing the action. However, this decision comes with its own set of implications. A change in action may require an understanding of habits and how to change them. A change in beliefs will alter one's personal vision, mission, and philosophy.
Shameless self-promotion warning!
