Answer:
Research confirms that an effective way to reduce prejudice is through intergroup contact in racially and ethnicallly diverse cooperative learning groups.
Explanation:
Research confirms that prejudice and stereotypes are constructed very early in life in a children's mind and world view, and the environment in which the kid is educated determines such stereotypes. If children grow up in a segregated environment and often listen to negative opinions about race they will begin to associate difference and diversity with negative characteristics and to validate and reproduce segregation. However if children are educated in an ethnically diverse environment and from an early age are encouraged to interact with people from other races, prejudice can be reduced.
