Success
tips Purpose of the course: let's start with the goals for this 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. Expending mental energy has never been found to harm anyone - on the contrary! Muscles are developed by straining them and not by lying on the couch, likewise, brain power is increased by straining the brain (i.e. thinking) and not by watching TV! How to study: best results come from understanding what you are doing. Understanding the material 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 tell or show me what you tried. Writing down the solutions on worksheets and tests: when you are writing up a problem, your goal is to convince me that you understand and can apply the technique needed to solve the problem. This means that the procedure is far more important than a correct answer and the only way I can evaluate your procedure is if you show it to me clearly. Thus, your work should show all the steps. If you are using a certain theorem, then say so. An answer to a question is not a 'Yes' or 'No', but a sentence with justification. Furthermore, there are certain rules ('mathematical grammar') how mathematical text is written down: follow them! (For example, the most common breach of these rules is when you write equals signs all over the place, often to mean 'it then follows'. Equals signs are for things that are equal and nothing else. You may use arrows to say 'it then follows'.) Even though I tend to take little off if you make a small algebra mistake, doing the computations correctly is important. One reason is that an error early on can either make the subsequent computation too difficult (so you are stuck) or too easy (so you are solving a simpler problem than I intended, which is worth less). Don't be lazy to write an extra line or a set of parentheses - a lot of points were lost by people who thought they could do things mentally. Again, don't forget that even if your answer is completely correct and it is clear that you could not have obtained it in any other way but by following the correct procedure, if I do not see this procedure on your paper I can give you only little credit. For you could have copied the correct answer from your neighbor! Finally, write your solutions 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. |
