The entire school funding debate in America is based on false premises.
Sorry, there just is no substitute for textbooks yet. I'm in my mid 30's working on a technical Ph.D., and even when I can download academic materials I just end up having to print them out.

Multimedia has its place, but only as a supplement to text-based instruction.
