To use this flash application simply enter a list of your students names or items that you want to randomly select, one per line. Then click the next button to let the computer start picking names.

Once a name has been picked it may be picked again but is less likely. This will keep students on their toes and help them pay attention while at the same time give everyone in the class a chance to participate.

Here is a little bit of Algebra research that I did between students grades and their ability to do their multiplication tables. I've posted results on my aschool blog.

While I was creating a presentation today and using Gimp to crop my screen shots is seemed really slow when I was pasting in the images. So I adventured into the preferences and discovered that there was an option to increase the number of processors. I haven't done any test yet but this should at least help some of the filters work faster.
