Describe the reality of living in a multicultural, "global" world: a world that has become a mix of cultures and nationalities. Emphasize the need and necessity of understanding different cultures. Give examples of a classroom where there are students from a variety of cultures and backgrounds.
Describe a teacher who is bicultural or multicultural, having a diverse family background or having been exposed to different cultures. She would be able to better understand the needs of multicultural children in the classroom, to cater to language requirements and to teach curriculum with sensitivity and awareness of cultural values.
Emphasize your ideas with examples and references in a step by step, point-wise manner. The multicultural teacher will be able to relate to problems arising from cultural barriers or taboos better than a teacher who is not so exposed or experienced. Organize your description so you are able to prove how children today need to have a similar exposure so that they can become free-thinkers.
