Great interview with Canadian primary teacher and author, Kathy Cassidy. Listen to her application of technology in the classroom with primary age students as she builds literacy and facilitates learning.
If you want to understand teens and their new social spaces and all of the implications that come along with that, Danah Boyd's new book, It's Complicated: The social lives of networked teens is a must-read.
This interview is on the topic of this research and her book.
