Ideally, education should incorporate both the width of the Internet and the depth of books. In our Theory of Knowledge class, we are currently experimenting with Twitter note-taking. While listening to a recorded lecture, students can ‘tweet’ concise messages highlighting a particularly interesting point or quote. Each tweet imparts depth of insight while our collective tweets provide breadth. ‘Groupthink’ activities are often criticized for inhibiting individual thought since people are inclined to minimize conflict by unanimous agreement. I believe that group discussion is not a melting pot of ideas but a forge from which new ideas can be shaped.
