1.The IQs among the students were within the normal range. 2.The study showed that a teacher's positive view and high expectations of students convinces them that they are gifted and enables them to do better than average work.

3.She did not see this as evidence that the student was not bright or capable, but rather viewed it as one day抯 poor performance, an exception to a normally good pattern of work.

4.It is hard to describe exactly, but her tone was assured and she did not express any negative qualities such as irony, putdowns and/or irritation.

5.This shows that positive expectation can be effective even on mice, who do not, of course, understand human language. 6.Labeling means thinking of people in terms of the general prejudices which we have about their nationality, their race, or their gender, rather than thinking of them as individuals. 7.Labels define a broad, heterogenerous group too specifically.
