I surfed in here via a link on cool free tools for use in the classroom. I felt certain that I had furled or "delicioused" a link to a site that has some little simple applications that teachers could use to liven up a classroom. I remember that one was a little .exe file that was a random student picker that might be used to choose the child to come to the smartboard or to answer a question, sort of "name in a hat style".
I was recently at a conference in London and the host, Ewan McIntosh used an application like this to pick speakers. Problem was, he was using a Mac so it is not likely to be available for the PC. Pity as it used a casino style fruit machine and looked like it would be great for the classroom. Anyone here know of anything like this?
