New technologies can dramatically change the way people live and work. Jet engines transformed travel. Television revolutionized news and entertainment. Computers and the Internet have transformed just about everything else. And now small video cameras have the potential to transform professional learning. Recognizing the potential of this new technology, researchers at the Kansas Coaching Project at the University of Kansas Center for Research on Learning conducted a three-year study to analyze what happens when coaches and teachers watch themselves on video. The results of this study show why these cameras are important and how they can be used by instructional coaches, individual learners, and teachers in the classroom and in study groups.
