TED Talk. Bill Gates: Teachers need real feedback

Until recently, many teachers only got one word of feedback a year: satisfactory. And with no feedback, no coaching, theres just no way to improve. Bill Gates suggests that even great teachers can get better with smart feedback and lays out a program from his foundation to bring it to every classroom. TED Talks is a video podcast of the best talks and performances from the TED Conference, where the world s leading thinkers and doers give the talk of their lives.
