Bracha Alpert has identified three different patterns of classroom discourse: (1) silent (the teacher talks almost all the time and asks only an occasional question),(2) controlled (as in the excerpt above), and (3) active (the teacher facilitates while the students talk primarily to each other).
However, in order to maintain the high level of discourse weâve all come to value and expect, please keep the following criteria in mind: 1  Enrich the conversation. 2  Stay focused and on track. 3  Be respectful.  Use standard writing 1  style. NOTE: Spam and/or promotional messages and links within a comment will be removed.
