My teacher gave me this fun assignment of reading these peoples essays and giving my opinion on it. The assignment for their essays was to write a short story of them as a different race and most of these students are white so their assignment was to write a story of them as a mexican, and since I'm hispanic, he wanted me to read them and put notes on them saying if their story does reflect on hispanics or if it sounds fake like they are overdoing it, but the only problem is that these are college kids and I'm a junior, I'm kind of nervous and don't know what kind of opionions to put on it, like if they are overdoing it on their essays, I don't want to be mean or if they did a good job, I don't want to just say good job.
I agree with DrBill, your not grading the papers, just giving your insight and input as a person who is hispanic. If it's a good essay, let them know why. If not, look to the positive insight suggestions.
Just be honest, by telling these students where they are right and where they are wrong is the only way for them to know. Just be honest and tell them what you think.
