Lots of buzz these days about "flipping the classroom" by using internet sites and video to do straight-forward presentations (e.g. factoring a quadratic) at home, and then using class time to extend and explore (e.g. "creating" a quadratic function to match the roots and vertex of a graph). See a lengthy interview in Wired magazine with Salman Khan, creator of Khan Academy.
This makes a lot of sense for my calculus classroom. How does it work, though, for an Algebra I class in which the students lack computers and internet access? The article profiles a classroom in Los Altos, in the Silicon Valley, and shows a student sitting at a computer in his kitchen. That is a far cry from the homes of many of our students.
