A couple of interesting sites before I drop off the face of the earth again...
Teachers TV is a website chock-full of videos and other stuff. Some good educational programs that you can show on your IWB. And from what I can tell, most videos can be downloaded. A possible downside might be that it's all British, but there are some worthwhile things in there. Have a look!
Oh, and the other day during my course, we looked at Kahootz. I've gotta say that as a first timer, I wasn't as excited as perhaps I could have been. I found it very difficult to position things (spatial awareness is probably not my strongest suit, but more than that, I found it really limiting in terms of what I could do. However, I'd be interested to see how the kids go at it. Mind you, I have enough trouble getting the kids through a lesson using word - with all the different abilities (or lack of them) - Kahootz almost seems like it will be too hard.
But we also heard about gamemaker, which I have just downloaded, but haven't really tried out yet. Will keep you posted...
Cheers, big ears!
