"Educational technology scholars recently advocated using social media such as Twitter in university courses based on research that it can increase students’ engagement in course material, increase student– instructor interactions and help students connect concepts with their application"

I wonder how that is going.....

"benefit from network effects that increase just-in-time access to information"

I think this is becoming more and more important, particularly in schools. Traditional textbooks are often so quickly outdated, it behooves the teacher and therefore the students to have access to good online sources.

This is an interesting idea to me and reminds me of Wikipedia.<br> http://www.livescience.com/32950-how-accurate-is-wikipedia.html

While there are issues with some articles in Wikipedia, there are also cases where it is better vetted by experts because so many have access to the information. It has become a place where the community can collectively gather and review information.
