I wrote an article not so long ago about how the iPad had a few shortfalls in working in an educational environment. Apple them self have admitted "it's not quite there' as an educational tool just yet. Hats off nonetheless to the Victorian State government for releasing 500 of these into our schools to see if and how they can enhance learning. We will watch with enthusiasm. Needless to say my school was not one of the trial schools selected. The full article explaining the rollout of iPad's trial can be viewed here.
I have been using this for a while now from the Victorian Department of Education and Early Childhood as part of their 1:1 net book trial that we are part of. 100 great activities in ICT. Nearly all of the software mentioned is freeware so you should not have any issue replicating them. Also don't forget to check out our teaching ideas section for 100 odd more and always growing. Hope you enjoy it and would love to hear if you anything similar.
