When appropriate, it is effective to incorporate the students' ideas into the teacher's restructuring of the response. Wait-time is the time after a student's response and before the teacher gives feedback. Wait time at this point encourages further student thinking. Teaching students what constitutes appropriate responses to various types of questions is important. A wide distribution of student responses is preferable to having only a few students actively involved.
Variety is the spice of life.
During a recitation, there are times when summarizing previously made points is helpful. Vary questioning techniques when dealing with lower-ability students. For example, you might provide longer wait-time, provide more cues and encourage further thinking after marginal responses.
