And that’s what has been wrong all along. Some time ago we started taking our walls too seriously – not just the walls of our classrooms, but also the metaphorical walls that we have constructed around our “subjects,” “disciplines,” and “courses.” McLuhan’s statement about the bewildered child confronting “the education establishment where information is scarce but ordered and structured by fragmented, classified patterns, subjects, and schedules” still holds true in most classrooms today. The walls have become so prominent that they are even reflected in our language, so that today there is something called “the real world” which is foreign and set apart from our schools. When somebody asks a question that seems irrelevant to this real world, we say that it is “merely academic.”
