New Post: 20 Years of SLA

What lessons have we learned as we open our doors for our 20th first day of school?

20 Years of SLA

Tomorrow morning, Science Leadership Academy opens its doors for the 20th time. To say that it has been a heck of a run is purely an understatement. In that time, we've worked with thousands of kids, and we've done all that we can to show the world that an inquiry driven, project based, caring school really can make a difference in the lives of the students and the educators who inhabit it.

What *JUST* happened in the Jaguars v. Chiefs game?

That was ridiculous.

I think Bader, Bohm and Stott are likely to come back.

And I know I should be more upset about Schwarber - losing him is brutal, and I am bummed... but JT is JT. He's a heart and soul guy for me.

If U.S. states have any degree of sovereignty, if there’s any states’ rights at all, it is the right not to be invaded by the armed forces of another U.S. state.

Baseball sucks. Football sucks. Life sucks. Everything sucks.

(I love soccer. Thank you, Philadelphia Union for giving me something to root for.)

Turner buys his own damn beer.

Turner never buys a beer in Philly ever again if he gets a hit here.

New Post: Meeting the Moment by Knowing Our History

Are educators ahistorical about their own profession?

What do the last 150 years of American public education teach us about how we must meet this current educational moment?

Meeting the Moment by Knowing Our History

Recently, I was lucky enough to talk to one of the truly transformational educators of the previous generation. They're getting older and starting to have some real health challenges, and they are someone who deserves all the flowers and thank yous for creating schools that changed the parameters of what many people - students, parents, educators, policy makers - thought school could be.
