The Smithsonian's "Educating Americans for the 21st Century" project is available online. Just when teachers thought they could forget about school and kick back with a cold diet cola, Smithsonian brings together a collection of articles sure to make you ponder, poke, prod, postulate, predict and plan for your continuing work in an ever-changing educational environment.

I don't have a particular article to recommend here - but the survey of issues os bound to provoke your critical thinking in an area or two. Maybe something sticks out to you as important or interesting? Feel free to respond with your comments as you get around to some "light" work-related reading during your summer break.
