Emphasize understanding; de-emphasize memorization:

Memorizing is not understanding. Unfortunately, many students have gotten by for a very long time on the basis of a sharp memory, and have never had to really think. Memorization may work for the moment, but after graduation when they are faced with new challenges, it is their ability to think and to understand that will carry the day, not their ability to memorize. I have seen too many examples of students who can memorize almost anything, yet cannot think through a simple extension of what they have memorized. I suggest they will not be prepared for what lies ahead after graduation, in work or in life.
