The latest catchword in educational circles is “constructivism, “applied both to learning theory and to epistemology—both to how people learn, and to the nature of knowledge. If we believe that knowledge consists of learning about the real world out there, then we endeavor first and foremost to understand that world, organize it in the most rational way possible, and, as teachers, present it to the learner. This view may still engage us in providing the learner with activities, with hands-on learning, with opportunities to experiment and manipulate the objects of the world, but the intention is always to make clear to the learner the structure of the world independent of the learner. We help the learner understand the world. But we don’t ask him to construct his or her own world.
