Unfortunately, many of these preconceived ideals are a part of cultural socialization and are hard to unlearn. Therefore, teachers need to be especially aware of these biases. An example of gender bias is that boys are often called upon more in a classroom. By the time girls graduate from college, teachers spent more than 1800 hours answering boy s questions than they did girl s questions. This is especially true in science and math courses.
Teachers also tend to accept wrong answers from girls and make boys work harder.
Racism Racism still exists today. Racism is not a genetic disease, but a learned trait. Racist attitudes and beliefs come from a mixture of misinformation and ignorance that is imposed upon young people. Racist attitudes are not voluntary. People choose to believe what represents the best thinking they can understand at a given time.
