Final answer:
The incorrect strategy for reducing bias in classrooms is 'Promoting stereotypes and prejudices,' while other strategies like using diverse teaching materials and encouraging cultural expression effectively contribute to a more equitable learning environment.
Step-by-step explanation:
The question asks about strategies to reduce bias in classrooms. The option that does not reduce bias is 'Promoting stereotypes and prejudices' as it contradicts the purpose of creating an inclusive and equitable learning environment. Instead, using diverse teaching materials, encouraging students to express their cultural identity, and emphasizing contributions of various cultures are proven methods toward minimizing biases. It's important to follow research-backed strategies like those seen in the Robbers Cave experiment and the jigsaw classroom model to connote inclusion and address prejudices. Bridging the educational gaps for students of color requires a recognition and appreciation of various cultural backgrounds and linguistic diversity. Training to reduce implicit biases can be effective, especially when accompanied by professional hiring practices that aim to minimize discrimination based on race or ethnicity, such as blind auditions or removing identifiable information from job applications to mitigate against unconscious biases.
