Assessment is not a spreadsheet -- it's a conversation.
I showed this to my Grade 8's awhile ago and they would agree! The would have liked to have known what long term impact the experiment had :)
Because knowing is only half the battle, and doing is the other half, I fear the long-term impact be less than impressive.
I love this commercial! I think it is a really good example of putting things in perspective. It would be interesting to create a similar themed video with students..
