One particular kind of follow up we did study was what we called "high-level
evaluation." Teachers often follow up student responses by elaborating
important implications they see. Teachers sometimes turn some of these
elaborations into didactic or instructive elucidations=97 little set=

students should not miss. Others are more serious explorations of lines of
inquiry opened up by students. When the latter occured, we coded teacher
evaluation as high-level: the teacher noted the importance of a student's
response in shaping a new understanding, and the course of interactions
changed some because of what the student had said. That is, we treated
evaluation as high level when a student contributed something new to the
discussion that modified the topic in some way, and was so acknowledged by
the teacher. Specifically, high-level evaluation consists of two parts:
1. The teacher's certification of the response and
2. The teacher's incorporation of the response into the discourse of the
class usually in the form of either an elaboration (or commentary) or a
follow-up question.
For level of evaluation to be high in our coding, the evaluation had to be
more than "Good," "Good idea," or a mere repeat of the student's answer.
The teacher had to push the student's contribution further, validating it in
such a way that it affected the subsequent course of the discussion. When a
teacher's evaluation is high level, the student really "gets the floor."
Hence, high-level evaluation, like authentic questions, directly affects the
dialogicality of teacher-student interaction.
On average, only 1% of the classes we observed in our ninth-grade study
involved high-level evaluation. This compared with 3% in eighth-grade
English classes.
