**In-class versus on-line.**There is almost universal agreement that**taking an online class is harder than taking a regular class covering the same material.**You may be wondering if you should take this class on-line or in-class. We offer both versions. The two versions cover the same material. Main advantages of the in-class sections include: regular personal contact with the instructor and fellow students, a regular opportunity to ask questions, and regular presentation of the material by an actual person. The main advantage of the on-line course is that you can work on it on your own schedule, and wherever it is convenient (literally anywhere on the planet). However, you should be aware that taking the online version is likely harder than taking the in class version, and you need to be prepared to work on your own. You do have access to the instructor, but the responsibility rest with you making first contact__when you__have questions. There is an “Email Instructor” button on each problem in WebWorks.The main requirements for taking the on-line version are

Availability of an internet browser such as Firefox or Internet Explorer.

Your ability and willingness to use e-mail.

Your ability to print postscript or pdf files. (This is not essential but highly desirable.)

The University also charges an extra fee for the administration of the course which is included in your registration.

E-mail is best. You can email me to make an appointment to visit me in my office, if you are in the Salt Lake City area. I can be available on Skype, if you wish to talk to me in person.**Course Contents:**The essence of**Algebra**is to use variables instead of numbers. This enables us to set up and solve word problems, and to construct a link between formulas and pictures which in turn much amplifies our problem solving ability. You don't need to understand all that follows, but for your information here is a list of the topics we will cover:Manipulation of algebraic expressions such as

*(a+x)*^{2}*=a*^{2}*+ 2ax + x*^{2}*.*Solution of linear equations such as

*3x+2 = 5 --> x = 1.*Solution of quadratic equations such as

*x*^{2}*-5x+6 = 0 --> x=2 or x=3.*Solution of linear systems such as

*2x+3y = 8 and 3x-y =1 --> x= 1 and y=2.*The concept of a

*function*.The Cartesian coordinate system and the graphs of equations and functions.

**Calculators:**Calculators are great tools, but at this level it is crucial to acquire arithmetic and algebraic proficiency that does not depend on the crutch of a calculator. That's why for exams (including the final) calculators are prohibited. Of course you can use calculators for the home work.**University versus High School Classes.**Some mathematics (essentially Intermediate Algebra through Calculus, and some basic statistics) are taught at High Schools as well as at a University level. There are two main differences between classes on the same subject taught at a University or a high school. The University class is faster paced, and at a University there is no supervision of your learning by the teacher. I will frequently make suggestions about how you should go about it, butare in charge of your learning. This is a difference in philosophy, not a matter of not caring. I measure my success by seeing how much students in this class learn, but I assume you are fully responsible and capable to make the best of what this class has to offer. I'd be pleased to talk with you about ways of maximizing your success. Don't hesitate to contact me if I can be of assistance.**you****What it Takes:**Taking any math class is a serious enterprise that requires your commitment, time, and energy. Obviously, we are all busy, and there are many competing claims to our attention, all of which are legitimate. So it's not a moral problem if you don't have enough time to dedicate to this class. But it is a fact of life that understanding new mathematics takes a great deal of time and effort, and if you are not prepared to spend that time and effort you will not understand the mathematics. As a guide-line you should count on spending a total of about 12 hours per week on the lessons, approximately and on average. Moreover, you should be able to spend that time in good sized chunks without distractions. If you are unable to spend that kind of time, you are better off taking Intermediate Algebra through a different delivery method.**I'm not a math person.**Many people feel they are intrinsically unable to learn mathematics. This feeling is usually sincere, but it's also irrational, a poor excuse, and unnecessarily self-limiting. You may not be able to make mathematics your career, but anybody can study mathematics successfully. If you follow the suggestions given here in the next few paragraphs you will succeed!**Make sure you have the prerequisites:**Mathematics proceeds in a logical sequence, and you can't understand new mathematics if you don't understand what underlies it. For this class this means you must understand basic arithmetic, including the arithmetic of fractions, equalities, and inequalities. You should also have seen the concept of using variables instead of numbers, and you should understand the basic conventions of arithmetic precedence, and the use of parentheses. The latter seems to be the greatest stumbling block in using WeBWorK and we will review and discuss this issue in some detail.**Make sure you do not fall behind:**This is the most important suggestion on this page! If you miss just one key idea you will not properly understand what we are doing and your subsequent time and effort will be wasted. Saving two hours today may result in wasting days and weeks later. So before doing the WeBWorK home work read the relevant sections of the optional textbook and the pertinent web pages. Make sure you understand the subject. If there is a problem on the homework that you are unable to solve or where you do not fully understand the question and the answer, do not allow yourself to be satisfied with only a partial understanding of the issues. Go back over the relevant material, and go on only after everything makes sense to you.**Seek Help:**Work with friends or study partners. It's OK if you and your partner or partners have different levels of experience or ability. One of you will benefit from explaining something and the other from having something explained again in a different way. Use our free tutoring service in the Math Center, if you are located near the University of Utah campus. You are welcome to ask me questions by phone, e-mail, or by just dropping by.**Focus on understanding the subject**rather than memorizing recipes for doing simple things. You understand a piece of mathematics if you can explain it in terms of simpler mathematics, you can make multiple logical connections between different facts and concepts, and you can figure out how to apply the mathematics to solve new problems. Too much teaching of mathematics is directed towards memorizing and rehearsing the application of simple recipes to narrow classes of problems. Focusing on the underlying connections and learning how to figure things out is vastly more efficient and empowering than trying to memorize countless formulas.**You can learn mathematics only by doing mathematics.**The main purpose of the WeBWorK assignments in this class is to give you a guided opportunity to learn by doing. But you have to go beyond that! Which and how many additional exercises you should do depends on your background, your current understanding, and your interests. Rather than giving you a list of exercises I believe you are better served by your picking the exercises yourself and me giving you just some general guidelines. The best way to find good exercises is to make them up yourself, but there are also a great many exercises in the optional textbook, ranging from very simple problems letting you practice just one specific technique to quite sophisticated and deep questions.**Always Check your Answers:**Everybody makes mistakes, and you simply have to recognize that fact and guard against it. You should always check your answers. The answers to odd numbered problems are in the optional book, but that should not discourage you from working even numbered problems or making up your own. You can check your answers by computing the same result in different ways, by checking for plausibility and consistency, or by using more specific techniques such as substituting in the original function or equation, drawing a graph, or making sure that physical units are consistent. (For example, if your analysis calls for adding two seconds to a square foot then something must have gone wrong.) One major checking technique deserves it own paragraph.**Always Have Expectations:**Before you enter into any calculations think about what kind of answer you expect. When you are through compare your answer to your expectations. There are several possibilities. Your answer may meet your expectations. That's great, it will give you a warm and gratifying feeling, even though you may not have learned a lot. If the answer differs from your expectations then there are two possibilities: you may have made a mistake and you are now alerted to that fact, and you can figure out what went wrong. Or, and this is the most exciting case, there is something you misunderstood before you began work on this problem, and now you can improve and correct your understanding, and learn something new!**Hostile Testing:**No, this phrase does not refer to the testing we inflict upon our students! It means that you approach your answer with the expectation that it's wrong and you try to prove that it is wrong. That way, if you fail, then maybe your answer is actually correct! Apply the same attitude to your optional textbook and to what your teacher tells you. You are more likely to find errors, and you end up processing what you read or hear with a much higher degree of awareness and effectiveness.**Language:**Part of learning mathematics is learning the language of mathematics, and mastering the language is essential for understanding mathematics and communicating it to your peers and others. Make a habit of having your optional textbook and a standard dictionary handy, and when there is a word you don't understand figure out what it is before you read on. This will cost you some time at the moment but in the long run it will save you time, and it will help you understand the subject much better. It will also make you a more effective problem solver and communicator.**How to Work:**You are probably familiar with a mode of mathematics teaching that goes like this: Here is how you solve a quadratic equation, now go and solve problems 1--100 in your textbook. This is not productive because it turns home work into a chore that needs to be gotten over with, but that is neither enjoyable nor useful. It is much better to solve only a few problems but to go about them deliberately and carefully, with an eye towards noticing what the problem teaches you, and a determination to solve the problem correctly and to understand every detail of it. It is also important to organize your work in such a way that you can go back and see what you did and figure out what you did wrong. When you see my office you will notice that I am not a neatness freak, but in doing mathematics careful and deliberate neatness actually saves you time and enhances your learning experience.**How to take Exams:**There is only one fundamental way to prepare for an exam: make sure you understand the material. Rather than worrying about what specific problems might or might not be on the test, just make sure the mathematics covered by the test make sense to you, following the suggestions above. Here are some more suggestions specifically with respect to exams:**Cramming does not work.**That is particularly true in mathematics. Instead study steadily throughout the semester, and**relax**and do something fun the day or the night before the exam.It seems that there is

**always**someone who is late for a proctored exam. It may be a trite thing to say, but there is no benefit in being late! Make sure you come to the exam**on time**and unflustered by having to rush and worry. Just allocate a little more time to your commute than you would normally.When you actually receive the exam,

**relax**, and read all the instructions and all the problems,**before**you start working on any of them.Then do those problems that are easy or obvious. Not only does that give you a good start but also it may teach you or remind you of something that's useful for the other problems. There is rarely a good reason to do the problems in exact sequence in which they appear on your piece of paper.

If you get stuck put that problem aside and return to it after you are done with the more tractable problems.

When you are through and there is time left,

**don't leave!**Instead, check your answers and make sure they are correct. You've spent a lot of time and money getting to the stage where you are taking that exam, and a lot is riding on it. Being able to correct a mistake you made far outweighs the benefits of being able to spend 20 minutes more on whatever else you like to do.Even if you feel you don't understand a question, or several questions, at all, don't just leave. Write what you do understand and spend all the time you have available trying to figure out even those problems that appear hopeless.

After the exam go over the answers as soon as they are available. The exam is not an end in itself, you are here to learn the subject, and reading and thinking about problems you have just wrestled with is extremely helpful in this process.
