Reading: The teacher-expectancy effect refers to the tendency of students to perform to the level of their teachers' expectations. Listening: The professor used to teach a sixth grader Robber, who is quiet and sloppy dressed The professor left Robber in the slower-paced math group, and Robber never volunteered in class, did not do his homework and just passed the test; however, when the professor moved him to the advanced group, Robber was more energized by the fast pace, started to do his homework and ended as one of the best students in class.
