Short-term impacts and long-term impacts
I am gathering information to put together a semseter (or year?) of curriclulum for a new class I will be teaching. I hope it will encompass all of the 21st century elements which would have a short-term impact in terms of what students will know and be able to do immediately and a long-term impact that will impact their learnign for ever after...

Obstacles
Well, I hope I won't have any! :)
P and P can continue to be amazing over the next two days and continue showing us all of this cool stuff. Thanks!
