I also read an interesting article by a guy called George Couros
He talks about the value of open reflection, the development of literacy with different mediums, student voice, and the ability to track your learning. What was really interesting was his last reason relates to the above snip. It is developing a positive digital footprint. We probably need to be teaching children about how their blog can help them in their future. The emphasis is on well Googled as they could just as easily have negative posts come up that they cannot get rid of! It's a short but interesting read. http://georgecouros.ca/blog/archives/3721
