Do you ever have those moment when you start to think about something and then actually get worried or befuddled (<--great word!) as your thoughts progress. I often get it when I start to think about the vastness of space or whether there is an afterlife or even is that table actually made of atoms. I was talking to the students about effective use of technology within sessions and we started to wonder what possibilities might be available for the use of technology in the future and how it would support teaching and, more importantly, learning. I continued after the session in my thoughts and the possibilities might indeed be considered scary!
