"To students, teachers are critically important role models because of what they are all still learning, not just because of what they already know. It is as experienced learners, with a high interest in and high standards for knowledge and skills, that we communicate the lasting value of these things to students. The obverse is also true: when we are no longer learning , we no longer teach, because we have lost the power to exemplify for young people what it means to be intellectually active." (Fried, p25)
