There is the hackneyed notion that a good teacher is the most critical thing to the educational process. And it's wrong. In the marketplace for ideas, the ideas and the content and the curriculum should be central, not a cult of personality. And if you package data, process, facts sufficiently well, they should pull the student into the curriculum, into the knowledge base. And the teacher can be there to help facilitate other areas.
People talk about class size.
You should have an individualized curriculum for the student in real time, on demand. Clearly, that won't happen if you have a human being there. And the money spent in the technologically assisted systems. I'm doing a lot of research on this. I actually also believe that there's some interesting technology.
