The document argues that schools should not block social networking sites because some can be used for engaged learning by students. It suggests that blocking sites that excite and engage students in lessons is counterproductive for teachers who want engaged students. It asks schools to reconsider what engaged learning means and whether social networks like Skype could work for classroom lessons, as demonstrated by some students, and enable global collaboration. The document questions why schools would block tools they don't understand could be used for debates, opinions, and finding out what's happening in the world, when such skills are needed for future jobs.
