Web 2.0 in the classroom

I’m an EFL graduate teacher from Argentina. I’m currently working – and hope I’ll still be for many years to come – at a state public school. I’ve been teaching English for eleven years both at public and private schools and academies.
Having worked with blogs for a little while and, to tell the truth, not knowing very much about them or other web 2.0 tools and applications; I’ve decided I’ll try to learn as much as I can about this wonderful and fascinating world in which we can play an active role in adding content to the world wide web, and not just be mere spectators.
I’ll use this blog as my personal journal, where I’ll display what I learn.
I’ll start with some useful tutorials and definitions which helped me grasp what all this web 2.0 stuff is about.
