This is a link to the text of his speech (or prepared remarks at least) that he will give as a 'back-to-school' speech aimed at students across the US. Firstly, what a good idea - I believe the president does it every year, secondly I bet it sounds better from Obama that it did from old GWB.
The whole thing is worth reading and if I can locate a video I'll post tomorrow, but below is my favourite bit. It is basically a big 'shout-out' to teachers - now wouldn't it be nice if our PM or Ed Sec said something similar (fat chance!)
“Now, teachers are the men and women who might be
working harder than anybody. Whether you go to a big school or a small one,
whether you attend a public, private, or charter school – your teachers are
giving up their weekends and waking up at dawn. They’re cramming their days
full of classes and extra-curriculars. Then they’re going home, eating some
dinner, and staying up past midnight to grade your papers.
And they don’t do it for a fancy office or a big
salary. They do it for you. They live for those moments when something clicks,
when you amaze them with your intellect and they see the kind of person you can
become. They know that you’ll be the citizens and leaders who take us into
tomorrow. They know that you’re the future.”
