growing critics and creators

While visiting family for a while I am catching up on some reading:

"Knowledge is not what's true; it's what helps. Knowledge is what you use to get things done. It's situational and contingent. So we need to help people who are willing and able to critique, integrate, elaborate, challenge and work on and with the knowledge they come across. They need to see themselves less as nervous supplicants at the alter of knowledge and more as confident critics and creators. And they need to be skilled at doing it well."

How do you "work on and with" the knowledge you come across in your days?
