About Homework
So it happens that in a large university, we ask students to hand in
well written homeworks which are clearly formatted, written
in clean mathematical English, and consistent with standard mathematical
convention. I know, it sounds downright humorous when put so plainly.
In any case, it is clear that we often don't demonstrate how
a student should go about this task, having read little to no mathematical
literature and equipped with only the basic writing skills expected
of any entering UC student. Thus, I have posted the following
references to some examples which make clear what is expected. If you are
a student, I urge you to take the time to examine these links.
Ross' Surefire Tips for Suceeding in Math
- Do your homework! Seriously, mathematics is a creative endeavor which involves thinking deeply about why things work. The only way to gain such understanding is to buckle down and tackle problems. Don't kid yourself; if you haven't sat down and really thought about the problems, you haven't learned anything. If you find yourself spending lots of time memorizing, you're not doing mathematics.
- Ask Questions. This includes asking your professor questions, your TA, your fellow students, and most importantly yourself. To learn math you must constantly ask questions and try to answer them, thus prompting more questions. Asking others adds new ideas, as well as forces you to better understand your problem.
- Avoid Solution Manuals. There's no better way to convince yourself that you've learned something and actually have learned nothing than to read
solution manuals. Checking your solution (e.g. comparing against the
number in the back of the book) is valuable so long as it causes you to reconsider a problem you've gotten wrong; copying a written solution has almost no value. As a further note, most “Student Solution Manuals” are reprinted solution manuals meant for your teachers. Hence, they are written as solution sketches, missing many details and concepts which are necessary for a complete solution.
- Spend enough time to understand. It is amazing how much repeated
exposure to mathematics helps understanding. Don't cheat yourself; spend
time solving problems and making completely clear any concept which seems mysterious. In other disciplines, memorization and bullshit will get you a long way - you'll find this is not true in mathematics.
- They're problems, not exercises. My last point is philosophical.
When you are asked to do homework, approach your homework as a set of
problems to be solved by understanding how they work and how
you can get to your conclusion. We learn only when we are confronted
with a challenge, think about how it works, and understand our solution
when we (hopefully) come up with it. If you are not solving problems
but just moving symbols around in immitation of something you've been taught,
you will learn very little. Real life is a series of challenging problems—those
who have done nothing but exercises will find themselves hardpressed
to meet the challenge.
