How can teachers improve their feedback to students?

Here is my presentation about improving the process of evaluation for students and teachers. Might start with adding to the open-source app Classdroid. Apparently there are lots of brilliant and affordable programmers at Hackathons.

Un-conferencing at UC-Berkeley, on the topic of education technology. Lots of interesting folks here: a  medley of educators, techies, and do-gooders. Just met a young fellow who, in his spare time, uses the Pixar film-making software to create comics about the innate goodness of humanity, 1000 years from now, when overrun by technology (robots). Madbots.com.

It's obvious there's lots of goodness right now, all of these brilliant people are here using their skills and creativity to improve education.
