Previous temporal assumptions are no longer valid. The challenge is to use new technologies to restructure the educational system to meet the demands of a world in technological revolution. Educational constructs designed for a simpler world cannot accommodate the manipulation and synthesis of the quantity of information necessary to prepare students for today's complex environment. Teachers can no longer be expected to know everything in their field, and it would be a disservice to students to limit learning to their experience. Knowledge is dynamic.
Information often changes, reformulates, grows instantly.
Technology allows the teacher and students access. Thus, a critical role of the teacher is to make information available and, more importantly, to make it relevant. Now, machines can best undertake mechanical tasks such as calculation, typing and even spelling. Students have to go beyond the basics. They must be able to manipulate and use information.
