Success
Tips Purpose of the course: let's start with the goals of the course. Our purpose is to learn the language of linear algebra, master its concepts and procedures, learn how to apply them and learn how to speak and write mathematical material. Another goal of this course is to exercise your ability to think, something that will benefit you even if you never use the material we covered. Presumably we come to college with the purpose of developing our brain. If the goal was to develop and tone our muscles, no one would question that a regular and sometimes strenuous physical exercise was necessary, rather than lying on the couch. Brain power works the same way: it is increased by straining the brain through thinking, making connections, and yes, memorizing, and not by watching TV! How to study: best results come from understanding what you are doing. Understanding comes with a higher initial time investment, but it pays off later. The first thing on a student's mind is usually solving problems given for homework. HOW NOT TO DO HOMEWORK is to look at the homework problem and flip back through the section in search of similar problems. (You might as well admit it - you do it, don't you?). Instead, you should do the following:
Getting help: if you are having trouble, come and see me during office hours (or arrange a time with me if you can't make it to any of the office hours). Do this as soon as possible and not fifteen minutes before a quiz or two days before the test! Note, however, that office hours should not be viewed as free tutoring in that you come with a blank sheet and I work out the problems for you. You should have attempted the problems you couldn't do on your own and should be prepared to show me what you tried. Writing down the solutions on homework and tests: in this course, we will be writing many proofs. The book outlines some good practices when writing them, and you should follow these. Usually, it's not a good idea to plunge into writing a proof right away: you should make a few notes aside to help you get to the gist of the idea. Once you see the gist of the proof, then write it in longhand. Your goal is to convince me that you understand what you are trying to prove and how to go about it, which often involves neither too little, nor too much writing. It is a good idea to reread your proof after you are done and check whether an informed reader who sees your text for the first time would be able to understand it. Finally, write neatly and in an organized way. Messy and unorganized papers annoy me and leave me with the impression that you don't know what you are doing. Now, DO YOU WANT ME TO BE ANNOYED AND UNDER THE IMPRESSION YOU DON'T KNOW WHAT YOU ARE DOING WHEN I AM DECIDING HOW MANY POINTS TO AWARD TO YOUR EFFORT? Preparing for a test: if you did the work assigned for homework, this should simply amount to reviewing. Start several days before the test. Make sure you have all the basic stuff down (most of the tests usually deal with basic skills, only a few problems are more involved). Look at the review problems at the end of the chapter and work on them. If some of them are not going so well, find the section from which they were taken and study it again. Finally, and this is probably the single most important piece of test-taking advice that I can give you, as well as the most ignored one: GET ENOUGH SLEEP on the night before the exam. Those extra hours of cramming beyond midnight are seldom worth more than having a clear and refreshed mind. I don't even want to give any advice to people who start studying seriously the day before the exam. This is a very ineffective method so don't be surprised if it gives poor results. Taking the
test: you
probably know these tips already. Do the easy problems
first.
Since a lot of people do the problems in the order they are given, I
try
to arrange the problems so they go from the straightforward ones to the
more involved ones (though sometimes the availability of space on pages
interferes with this plan). If you don't have a clue on how
to even start a problem, skip it and come back to it later. Also,
it can't hurt to ask me a question about a problem during the test -
the
worst that can happen is that I tell you that I cannot answer the
question
or that this is a problem you should know how to do because we did it
in
class. |
