Course Goals

Imagination is more important than knowledge. Albert Einstein

 

Einstein’s quote implies that although mathematical knowledge is important, it is imagination that allows you to utilize knowledge to attain personal goals. 

 

The course goals are to:

(1) stimulate your imagination

(2) enhance your understanding of mathematics at a conceptual level

(3) demonstrate and communicate your knowledge to others

(4) improve your use of self-assessment methods

(5) think critically

(6) develop effective study and group skills

(7) apply quantitative reasoning to real world contexts

(8) master the use of a scientific calculator as a tool for quantitative analysis

 

The structure of this course is designed to address these goals. You will be asked periodically throughout the quarter to provide input as to how well the course is addressing these goals.

Course Objectives

The course goals provide a foundation to develop mathematical knowledge and intellectual imagination.  This is accomplished through the study of mathematics concepts at a level that will enable you to think critically, demonstrate and communicate your knowledge to others, and apply those skills to real world contexts. Listed here are the mathematical skills you should be able to demonstrate upon completion of this course:

1.          Understand basic rules of exponents and how to work with negative exponents

2.          Ability to add, subtract, and multiply polynomials (introduction to division of polynomials)

3.          Recognize and use a variety of factoring methods

4.          Factoring common terms and trinomials with any leading coefficient

5.          Be able to recognize the difference of squares and use it to factor quickly

6.          Understand square root and know how to simplify radicals

7.          Apply quadratic equation to solve problems

8.          Understand how quadratic equations are related to parabolas

9.          Know how to graph a parabola accurately having been given its equation

10.       Know how to work with simple rational expressions

11.       Able to solve application problems and explain the mathematics in the context of the problem

 

Course Expectations

As a student in this course, you are expected to attend all class sessions, arrive on-time and be prepared for the daily lesson. Being prepared means that homework assignments are complete, and you have all the necessary supplies for full participation in the daily coursework, such as pencil, notebook paper, graph paper, straight-edge or ruler, and scientific calculator.

Assessment

Tests and Quizzes

Much of the learning in this class is done through group work, therefore group tests and quizzes are used to assess your understanding. This does NOT mean that you will get a group grade. Test problems are complex and require an explanation of your reasoning. The testing format provides an opportunity to discuss your solution process with group members prior to writing solution processes in your own words. A correct answer to a problem is sufficient for a passing grade (which is a 75% or a 2.0); however, if you wish to earn a higher grade, you must clearly communicate your thinking and demonstrate your solution process. The group work is designed to hone your communication skills (this is a course objective). The individual write-up is how you provide evidence of your understanding for a formal assessment grade. This process will be explained in more depth and your questions will be answered prior to the first formal quiz or test. You can go to the homework website and pull up sample quizzes/tests that you can practice on before the quiz/test.

 

Partnership/Small Group/Whole Class Activities

Communication is an important aspect of this class, therefore you are responsible for providing evidence that you understand the material presented. One way to do this is to fully participate in partnership, small group, and whole class activities. The partnership and small group formats provide support to: (1) ease math anxiety, (2) learn to work collaboratively, (3) develop problem solving and critical thinking skills, and (4) clearly communicate your solution process to convince others that your answer is correct. Also, you will be expected to summarize and communicate your group’s findings to the whole class. The small group you will be working with to do class work will be the same people in your quiz/test group; therefore it is important to contribute your thinking, questions, and insights to the collective process.  As a productive group member it is your responsibility to listen carefully, provide positive feedback, ask clarifying questions rather than depend upon assumptions, and share your thinking, concerns, and critique of solution processes with one another.   

 

Homework

Completing and submitting homework on time is essential as it prepares you to be a full participant in the class activities. For each assigned section, you should:

 

Reading Response Sheet: Study the assigned section and respond to the questions about the readings that are listed on the Course Calendar.

-    take notes and work through the sample problems

-    work through some of the problems at the end of the section

-    check your work with the answers at the back of the book or in your solution manual

-    write up your responses to the questions in the Course Calendar for that section

Hand-in your response sheet on the day it is listed on the Course Calendar. The response sheet is worth 10 participation points and can only be made up by handing it in on the day of your return to class after an absence.

 

When you feel confident that you understand the material presented in the section and can perform the required skills then complete the on-line assignment. I strongly recommend that you do the assignment each night so that you are prepared for the daily in-class assignment.

 

On-line assignment: Go to WAMAP: Online Homework Access, log in using your ‘first name’ space ‘last name’ as your student name and your pass code is your student number (with NO dashes). Find the homework section you just studied. Open and complete the problems for the section. You can print the problems, work on them off-line (get help at the math lab, etc.), and then go back to the computer to submit your answers. If you are NOT satisfied with the grade you receive, you can ask for a new problem. Once an assignment is submitted, the grade you receive is recorded. On-line assignments can be completed ahead of time; however the final submission date is midnight before the quiz/test. After midnight, you will not be able to earn credit for the on-line problems for those sections.

 

Daily in-class process

When you arrive in class, hand in your reading response sheet, pick up your file folder, and start working on the problems listed on the board. The problems are chosen to represent the important concepts covered in the section.  Start working on the problem assigned to your group first. When your group agrees to the solution process, have one person from the group put the solution steps on the board so that others in class can follow your solution process. Then you work on the other problems. As your group completes the other problems, either register your agreement with other groups’ solutions, or put up your own solutions. When done put your work in your folder. This process should only take 15—20 minutes of class time.

 

I will (1) share college announcements, (2) discuss the reading response questions handed in at the start of class, (3) take questions about procedures from the section, (4) discuss the in-class problem solutions posted on the board, and (5) introduce the mathematics concepts and procedures for that evening’s homework.

 

 

Grading

The proposed grade distribution is 40% class participation & homework, 60% quizzes and tests.

o        Quizzes and tests are given each week. Quiz problems are similar to the in-class problems worked on that week; while tests are cumulative, meaning that the test questions can be taken from any of the problems worked on in class to-date. Quizzes are worth 50 pts, Tests are 100 pts. Since quizzes and tests are designed for working in groups, it is important that you make every effort to attend, arrive on-time, and be prepared. There are NO make-up tests or quizzes. The lowest quiz grade will be dropped and the lowest test grade can be replaced with the grade received on the final exam. (On-line homework section problems must be electronically submitted prior to the test that assesses your understanding of the sections covered to-date.)

o        Final Exam is 100 pts and is a collection of problems similar to the ones presented in the daily class work that cover the material for the entire quarter. The final exam grade will replace the lowest test grade.

o        Participation: You will receive 10 points for each day that you attend class. Points are deducted if you arrive late or leave early, are not able to attend a session, and for disruptive and disrespectful behavior. Also, up to an additional 10 participation points can be earned if you hand in a reading response sheet for the section covered that day before group time is over (within the first 15 minutes of class.) If you are absent and want to receive the 10 points for the reading response sheet, then that must be submitted (email is fine) before the class session or immediately upon your return to class. The 10 attendance participation points cannot be made-up even for excused absences.

o        On-line homework is worth 10 homework points. Section problems are available on-line up until the day of the quiz/test (midnight before the quiz/test). Please check the Course Calendar for quiz/test dates.

100 > 94% = 4.0 > 3.9 = A

93 > 90% = 3.8 > 3.5 = A-

89 > 87% = 3.4 > 3.2 = B+

86 > 84% = 3.1 > 2.9 = B

83 > 80% = 2.8 > 2.5 = B-

79 > 77% = 2.4 > 2.2 = C+

76 > 74% = 2.1 > 1.9 = C

73 > 70% = 1.8 > 1.5 = C-

69 > 67% = 1.4 > 1.2 = D+   

66 > 64% = 1.1 > 0.9 = D

63 > 60% = 0.8 > 0.7 = D-

60% >      = 0.7 >       = E

 

If you feel that the grade distribution does not adequately reflect your understanding of the mathematics in this course, then I encourage you to make an appointment to discuss it with me during office hours. This must be done sometime before the last month of the quarter.

“NC” (No Credit) grades are NOT given under any circumstances. If you want to withdraw from the course, request a “W” grade before the published deadline. “I” (Incomplete) grades are only given in strict conformity with the college catalog. Specifically, a student must be in “good standing” to request an Incomplete.  For this course, “good standing” will mean, at a minimum, a current grade of at least 2.0. “I” grades can only be requested in situations and circumstances that are out of the control of the student…please read the catalog for details. I reserve all rights about when and if an “Incomplete” will be issued. It is your responsibility to request and submit the signatures and paperwork required for “W” and “I” grades by the deadlines established by the college.

Assistance

Late and Make-up Work

If you are unable to attend class contact me as soon as possible to explain the situation and discuss options. It is also important to notify your group members, as they will have to function without your input (you can also ask them to take notes during the classes that you cannot attend.)

 

Tutorial Assistance

I am available to help clarify or provide tutorial assistance. However, (since I have approximately 100 students each quarter) please discuss the problem with your group members first. Make an appointment to speak with me if your group members are unable to help you. I am also available to work with the whole group.

 

If you need tutoring assistance on a fairly regular basis, the math lab is in SAM106.

 

Individual Needs

For help with dealing with math phobia or test anxiety, please make an appointment to talk with me. We can discuss your particular issues and devise a plan to help you be successful.

 

Students with Disabilities Statement

Students with documented disabilities, who need course accommodations, have emergency medical information or require special arrangements for building evacuation should contact the instructor within the first week of class.

 

The instructor reserves the right to reasonably adjust this syllabus if deemed necessary and will make available written changes for students to add to this document.

 

Course Calendar

The Course Calendar is not fixed, but rather is a working document which may change as we progress through the material. I will inform you of any changes to the calendar as they arise.
