Who ever said being a scientific guinea pig couldn't be educational? With Steam for Schools, teachers can now use Portal 2's level editor to create lessons focused on boosting critical thinking, spatial reasoning and problem solving skills. Announced at the Games for Change festival in New York City, the educator edition of Steam comes with a free copy of Portal 2 and the Portal 2 Puzzle Maker. Students and teachers alike can use the tools to create puzzles, but distribution is handled by teachers alone. (That's right, kids -- no level sharing unless the teach says so.) An accompanying website serves as a gathering place for teachers to collaborate, and aims to provide sample lesson plans centered on science, technology, engineering and math. If you're an educator who can't wait to bring a Portal-assisted physics lesson to life, see the links below to sign up for the ongoing beta. Now if you'll excuse us, we're off to "study."
