Something that's going thru my head these days is the idea that reading and writing are key tools to help develop intelligence. I think it was the authors of "Teaching as a Subversive Activity" who wrote that better thinking (or intelligence) is "languaging".
It suddenly seems to me important that as many of my students develop their intelligence as far as they can as quickly as they can. The world seriously needs more intelligent people, coz the dummies are smothering this beautiful planet and its incomparably beautiful citizens, to death.
And blogging and ICT tools seem an excellent way to do that because they encourage spontaneous and self-initiated reading and writing and reflection.
