If you give thought to diversity in American classrooms, the problems seem to centre on women and persons of color. May be bias affects all groups, but they get worse when targeted at these two groups.
If you have grown up in diversity-rich areas you might have got a hang on moving in a diverse campus. You might view cultural diversity with a sense of wonder. You may see what is initially confusing with growing respect. You will consider difference as dynamic. You will understand it is all a matter of awareness.
I cannot understand why diversity in a campus is a “problem” at all. A person not of your race and color speaks English with a different accent? Has a different set of references? Likes music that is outdated? Shrinks from expressing opinions on certain topics? What in this situation makes you uneasy? But I do agree the topic is complicated and confusing.
To me diversity in a classroom is an enriching experience. Being in a mixed class is like traveling without visas and expenses. It is getting to know the world in a pleasant, friendly way. It is an opportunity to quench your curiosity about different part so the world.
If education is all about learning to get on in this world, about knowing how others different from us live, about immersing oneself in other cultures, about qualifying oneself for jobs in any part of the world, about being a global citizen, what can be better than a being in a classroom full of opportunities to learn?
Yet, adjusting to different cultures seems like a “need-training” task.
