Notice which students you tend to treat with leniency and adjust this behavior. Pay attention to your interactions with all students but especially with students who don't participate in class or those with whom you have a difficult relationship. Monitor your use of praise. Make certain all students are reinforced equally for their work and effort. Language - Bias in language is a subtle but powerful influence in creating or reinforcing prejudicial attitudes.
Bias occurs in both vocabulary and usage.
For example, using generic masculine occupational titles and pronouns presents an unreal picture of the workplace and can limit aspirations because people, especially children, tend to take language literally. Language can convey biased or ethnocentric attitudes. One doesn't usually point out that an individual is White or of European American heritage. The same rule should apply to all groups. These terms imply that the dominant culture is superior to other cultures or that other groups lack a culture.
