I have been wanting to try this out for quite sometime, but just never got it done.
This one can be used for one of my reading incentive programs. I haven't checked into this yet, but I expect I will be able to put this in my newsletter wiki for teachers to view and I can also show it to the students.
A few of the uses that come to mind are book reviews, short tutorials, and award list promotions. It' a great alternative to a powerpoint presentation, which is getting over-exposed in my opinion. This would also be useful to have prepared to use when I am out of the library, so whatever I planned to teach a class can still happen without me there!
