, courses, and instructors have different expectations for such an assignment. If you are not as to what your assignment actually entails, then you will have to talk with your instructor to get that clarified for yourself.
If you don't understand the content of the class that you are taking, you should also probably discuss that with your instructor and ask her to guide you towards some resources that can help you better the material she is trying to teach.
We'd be happy to help you think through some of your ideas for a proposal and/or answer a few basic questions about proposals in general. But you always have to keep in mind that we are just a bunch of strangers on the Internet who might have opinions about research that are NOT the same as those of your instructor. It will be up to you to take any of our comments and adapt them to the expectations of the particular class you are taking.
Good luck. Let us know how that meeting with your instructor goes.
