Active boards changed for complete the way we teach. The software that comes with the boards is already full of useful tools and functions but a very basic way to use the active boards it's as overhead projectors. I like to complement my lessons with short videos as I think visual learners and all the students have another chance to review a concept, in a different way. However showing a video should be a way to reinforce a concept, not the whole lesson itself.
I tried blinkx as it was suggested and I think it's a good tool. I'm posting 2 videos from youtube as I'm used to work with this website more often.
This video it's about the life cycle of the butterfly.
This second video it's about tornadoes.
