I invite them (teachers) to put their efforts into trying to elicit and understand someone else's explanation -- to join me in practicing teaching by listening rather than by explaining. p. 129

The essential element of having the students do the explaining is not the withholding of all the teacher's own thoughts. It is, rather, that the teacher not consider herself or himself the final arbiter of what the learner should think, not the creator of what the learner does think. The important job for the teacher is to keep trying to find out what sense the students are making. p. 133
