what am i going to do?

Part of my job as graduate research assistant is to transcribe video-recorded lessons for analysis. Two things I notice that come up alot in the novice teachers that I work with are:

1. Saying, "ok, what we're going to do today is, we're going to..."
2. Repeating a students answer verbatim, immediately after he/she says it,in the form of a question.For example; teacher: "why is the sky blue?" student: "because of the clouds." teacher: "because of the clouds?" In effect, the students will be conditioned to stop listening to the other students, because the teacher will repeat him/her.
