I just read a post from Will Richardson on literacy. He talks about the amount of information we process now and it is astronomical. One point he makes is that aside from organizing what he reads through del.icio.us and bloglines, he makes the information sticky by blogging it (just what I am doing now). Another point he makes is that students, faced with this enormous quantity of information are going to have to learn how to vet it and learn to recognize patterns in what they read.
I too have found that writing not only helps me retain what I read but also helps me understand what I read.
David Warlick talks about the 4 E's : exposing knowledge, employing information, expressing ideas, and ethics on the Internet. Education will have to change, but as I said in my last post - this is not easy.
