Math 120 - Intermediate Algebra

Syllabus

Instructor: David Arnold

Prerequisite Classes

Students entering the Intermediate Algebra course are required to show proof of a C or better in an Elementary Algebra course taken at a college. In lieu of this prerequisite, students can take an assessment test in the Academic Support Center (the ASC is in the library) to insure proper placement in the course. Students are advised to see a counselor as they can be quite helpful in placing students in a course commensurate with their ability and background in mathematics.

Schedule and Office Hours

Note: These are "official" office hours. However, I will make myself available whenever I can. Please do not be afraid to ask for help at any time as I am always eager to help.

Office Location and Phone

Cancelled Classes

Those driving long distances to attend classes are advised to call 476-4210 before driving to the CR campus. Choose #5 from a menu of choices. You will then be advised of any cancelled classes for the day in the Physical Sciences complex (math/science). Thus, you can avoid the frustration of driving to campus, only to find that your class has been cancelled.

Read the Updating Student Information section and adjust your personal information. Be sure to write down your login name and password for future reference. It is extremely important that your email address is current!

Once you login to Blackboard, locate your math class and take some time to find out what is provided. Then read the "Welcome Message" in the Discussion Board and reply to to the "Welcome Message" thread. In the future, use the Discussion Board to discuss issues and problems you are having with your class.

Getting Help

Help is available in many forms.

Classroom Environment

It is expected that everyone involved in this class, teacher and students alike, will act in a manner conducive to providing a comfortable environment for learning, a classroom where students feel free to ask and answer questions without fear of embarrassment or ridicule.

It is important to stay on task when class is in session. Hence, conversation not pertaining to the subject at hand should be taken outside the classroom.

I understand that students will have to get up and leave the room for various reasons and I also understand that students will arrive late from time to time. However, courtesy requires that you enter and leave as quietly as possible, without disturbing discussion or lecture.

It is essential for student success to maintain a good environment in the classroom. If you have any personal difficulties with the learning envrionment in the classroom, please visit me in my office to discuss them.

Texts

Students will be given a free Intermediate Algebra textbook on the first day of classes in the form of a CD. The book is written by the mathematics department and will be given free of charge to all students in intermediate algebra in the fall semester, 2007. When you load the CD into your computer, double-click the file start.html to view a table of contents.

The textbook files on the CD are in PDF format. You will need to download a free copy of the Acrobat Reader to read them. Click the following icon to obtain a free copy of the Acrobat Reader.

It is important that you have the most current version of the Acrobat Reader that your system will allow. The above links will take you to the Adobe site. Your system will be automatically analyzed and you will be informed of the optimal version of the reader for your system.

The Intermediate Algebra textbook is also available online at:

http://msenux.redwoods.edu/IntAlgText/

The online files are identical to the files on the CD and include:

  1. A file for each chapter, which includes exercises and short answers.
  2. Separate files for each section in each chapter.
  3. Separate files for exercises and short answers for each section.
  4. Separate files for exercises and complete solutions for each section.
  5. A single file that contains all exercises and short answers for each chapter.
  6. A single file that contains all exercises and full solutions for each chapter.

This is a third edition of the text, but errors will still exist. We've started an errata page at:

Expect that this page will be updated frequently throughout the semester.

Paper Copies are available:

Reading the Textbook

It is important that you read and work the examples in the textbook before attemping the exercises. Many students will work the process in reverse. That is, they begin working the exercises, then if stuck, they page back through the narrative in the text seeking a similar example to the exercise on which they are working. This is not a recommended approach to the study of mathematics.

With a textbook on CD and/or online, it seems even more tempting to work the reverse process (exercises first, then the reading). There are a number of ways that you can combat this temptation.

Whatever your approach, reading the narrative online, printing out pages on your home printer, or purchasing the printed version of the textbook from the bookstore, it is essential that you read each section before attempting the exercises at the end of the section. And, by reading, we mean pencil in hand and scratch paper at the ready to work out the examples as you read. You should not read a mathematics text as if it were a novel.

Calculators

The TI graphing calculator is required in all intermediate algebra courses. If you have a TI82, it will suffice, as will a TI83, TI83+, TI84, or TI84+. However, if you plan on purchasing a new calculator, we recommend the TI84 Plus.

Kevin Yokoyama has developed a calculator help tutorial. The web address is

http://online.redwoods.edu/INSTRUCT/KIYOKOYA/TIHelp/index.htm

The Mathematics Department has a limited number of calculators that it rents to students each semester. There is a one-time, non-refundable fee of $20. To rent a calculator, please follow these steps:

  1. Contact Eloise Cottrell in the Physical Science Office, 476-4211. Ask if she has calculators available to rent for Mathematics.
  2. If there still are calculators available, go to the Cashier in Enrollment Services and ask to pay a $20 fee for a calculator.
  3. Bring your receipt from the Cashier's office to Eloise Cottrell at the Physical Science Office. Eloise will handle the remaining details of the contract.

Examinations

We will have 3-4 midterm examinations and a comprehensive final examination. Students should sit for both examinations on the day that they are administered. If you miss an examination, there is no guarantee that you will be allowed to make up the examination. Indeed, makeup examinations are given only at the instructor's discretion.

Students who need special arrangements for examinations are expected to meet with the instructor before each examination to insure that all examination materials are on file in the Academic Support Center (the ASC is in the Learning Resource Center (library)).

If you know ahead of time that you have a conflict that will prevent you from sitting for an examination, please meet with me to discuss alternatives.

Every student will be required to sit for a final, cumulative examination. The time and day of this examination is posted in the Schedule of Classes and students are expected to sit for the exam at the time and on the day posted. No exceptions. Any student failing to sit for the final examination will receive an F in the class. Please keep this in mind when making travel plans for December. Plan ahead!

Online Quizzes

We will use the Online Practice and Testing in Mathematics (OPTIMATH) system to administer quizzes during the semester. Here is the link:
http://msenux.redwoods.edu/optimath

You will take approximately 9 required quizzes. We might also offer some extra credit opportunities through this system as the semester progresses.

The OPTIMATH testing system uses PDF format. You will need to download a free copy of the Acrobat Reader to take the online quizzes. Click the following icon to obtain a free copy of the Acrobat Reader.

It is important that you have the most current version of the Acrobat Reader that your system will allow. The above links will take you to the Adobe site. Your system will be automatically analyzed and you will be informed of the optimal version of the reader for your system.

Assistance for using the online testing system can be found at

Homework

Homework will be assigned daily and will be due the next class meeting. Each homework will be assigned a grade ranging from 0-10 points, bases on completeness, the following of directions, and the quality of work.

It is essential that students keep up with the homework on a daily basis. Each time you come to class without your homework, you are not prepared to take part in the class at a level geared to your success. Therefore, students are encouraged to hand in homework on time. However, I am acutely aware of the responsibilities that many students have to deal with outside the classroom. Consequently, I do allow a "grace period" of one class period for late work. That is, if you hand your homework in by the next class period, I will still accept the assignment. However, there is an automatic 2-point deduction for late work. Homework later than one class period will not be accepted.

If you are experiencing difficulty getting your homework in on time, or if you know an upcoming event will interfere with getting your homework in on time, please discuss this with your instructor. We can possibly make some arrangment to help facilitate the completion of your work.

In order to facilitate the recording of homework scores, students are required to place their name in the upper right-hand corner of their homework assignment and staple the pages together with a single staple in the upper left-hand corner. On the first line of the of the first page of your homework, please write down the assignment number, the pages that encompass the assignement, and list each exercise number assigned. For example, the first line of your homework might read:

Assignment #12, Page 150, #1, 3, 5, 7, 8, 10, 11, 23, 45

Grades

Your homework, quizzes, and examinations will be weighted and averaged to determine your final grade in the class. A running account of your work can always be viewed in your gradebook on Blackboard.

When Problems Arise

Should problems arise during the semester, always contact your instructor to let me know what's going on. That's the only way I can help.

The Syllabus is Subject to Change

As your instructor, I reserve the right to make adjustments to the syllabus should things not proceed as smoothly as expected. However, in general, I do not anticipate making changes.
