Students need to feel that the classroom is a safe environment which welcomes their inquiry and supports the entire process of learning, and not just the resulting bits of knowledge which constitute "the right answer." The imbalance of power inherent in the IRE model (teacher Initiation-student Response-teacher Evaluation) is not conducive to this feeling. Also, students need to feel that their own knowledge is as valuable as the knowledge possessed by the teacher. This is not to say that students should be encouraged to perpetuate uneducated misconceptions or should be rewarded for inaccurate information; however, students must be allowed to express their ideas by initiating comments and clarify confusion by initiating questions. Also, students should not feel that they will be penalized for "the wrong answer" during the learning process, or they will never gain the confidence to actively participate in the search for gaining understanding
I have spent a lot of time in public classrooms lately, and noticed a strong degree of passivity required by teachers of students. I think this is sad and wrong. The Initiation Response Evaluation model is the model commonly seen in U.S. schools of a teacher initiating a question (with a predetermined 'right' answer in mind) the student responding, and the teacher evaluating the response. Young children associate having the 'right' answer with being 'good' and 'smart'. Sometimes a child will offer a very intelligent answer, but because it wasn't the answer the teacher was looking for she make the child feel wrong. I was talking to a group of third graders at recess who thought they had found gold. I asked a little boy what he was going to do with it. He said, "Buy a school." I asked what he was going to do with a school. He said, "Blow it up."
