"Traditional instruction places far too much emphasis on content. The problem
isn't just that what students need to know can't be known. The unreasonable
amount of information dumped on them, the brief life in memory of most of
it, and easy electronic access to a near-infinite amount of it, make merely
delivering information a poor use of time. Focusing on the real world rather
than on second-hand textbook versions of reality, and understanding the
process by means of which sense is made of that world, are keys to new
worlds of performance."
