Tom Barrett is one of those inspiring teachers who is soooo generous with his ideas that other teachers can't wait to share along with him.
If you haven't seen his Interesting Ways series before then head along to http://edte.ch/blog/interesting-ways/ where you'll find a series of great crowd-sourced presentations that can be used today in the classroom.
I had a look this week at Use your Interactive Whiteboard in the classroom. It's all too easy to use the IWB as a projector/glorified chalkboard. The ideas on this link show how much more an IWB can be.
