Jeanne, unconventional is GOOD as our students today and very unconventional. I also like the idea of taking students a little out of their comfort zone. I do not know the source but I was tinkering around the Internet one day and came across a very cool diagram where there are two circles One small circle is labeled "Your Comfort Zone" and another large circle separate and to the left was labeled "Where the magic happens" and it really hit home with me and was a great description of where much of the research on teaching and learning has taken us today.
