Who knew that powerpoints could be fun!?!?  I had no idea that powerpoints could be used in a non-linear fashion.  Maybe it's because I'm very analytical, so thinking in a non-linear way is out of the box for me!  Non-linear powerpoints allow students to become active learners rather than passive participants.  I am excited to develop one myself, but I have to admit that I was a little anxious about selecting a subject that would work in a non-linear fashion.  Being a potential science teacher, I think a lot of things in the science realm are very linear - cycles, processes, etc.  However, I think I will develop a non-linear powerpoint as a review system, such as a Jeopardy or Who Wants to Be a Millionaire? game.
