Talk Meters

Yesterday, I came across an article about a new tool called a Talk Meter . The idea is that a tutor can use a device like a Fitbit to measure how much time the tutor is talking with a student versus how much time the student is talking. It seems like a straightforward tool that might help to train the tutor to allow the student more opportunities to speak. The question is whether or not having the student speak more (or less) than the tutor has any inherent instructional value. It is an interesting concept to study in a rigorous academic setting.
