It's kind of hard if you don't tell us what class you are talking about. Here's what I thought up:
Should we have a fence on our southern border or an open border policy with work visas? Do your research using answers from hispanics who are American citizens vs undocumented students.
What kind of demographics/people use medical tourism?
Should high school students have the option of being apprentices and getting a technical-degree diploma that will help them get a job? It would be an alternative to the usual college prep classes.
Are students more likely to graduate from college if their parents went to college?
Will dorm food make you fat?
Do students who live in dorms get better grades than students who live on greek row or in off-campus apartments?
Do students learn anything from writing research papers? What have students learned from writing research papers?
What is the optimal number of hours to cram, then sleep, to do well on an exam?
