What is one way teacher expectations can be harmful?

Teacher expectations can significantly impact students' self-esteem and overall academic performance. When educators set low expectations for certain students, these individuals may internalize the belief that they are incapable of achieving at a higher level, leading to diminished confidence in their abilities. This lack of confidence can create a self-fulfilling prophecy, where students who feel they are not expected to do well may not put forth the effort needed to succeed, thus reinforcing the low expectations held by their teachers.

In contrast, high expectations can inspire students to strive for better performance, enhance their self-worth, and promote engagement in their learning. Therefore, when expectations are not aligned with a student's potential, it can indeed result in lower self-esteem and hinder their academic and personal growth.
