REQUIRED TEXT: Elementary and Intermediate Algebra, by Mark Dugopolsky

RECOMMENDED TEXT: Student Solution Manual, prepared by Mark Dugopolsky

COUSE DESCRIPTION: This course is a continuation of MAT 152A. Topics covered will include factoring, solving equations with rational and radical expressions, systems of linear equations and solving quadratic equations.

STUDENT OUTCOMES: The successful student will

1. exhibit a proficiency in the topics covered in the course;

2. engage in logical and critical thinking;

3. read technical information; and

4. demonstrate the solution to problems by translating written language into mathematical statements, interpreting information, sketching relevant diagrams, analyzing given information, formulating appropriate mathematical statements, and checking and verifying results.

PREREQUISITE: A grade of C or better in Math 152A or equivalent, or satisfactory score in Mathematics Assessment Test.

GRADING POLICY: GRADING SCALE:

Homework 20% A 90%-100%

Quizzes 10% B 80%-89%

Exams 40% C 70%-79%

Final 30% D 60%-69%

F less than 60%

EXAM POLICY: Grading will be based on progress towards the final answer, and the demonstration of understanding of the concept that is being tested. The more you show me with steps and detail, the better your chances for partial credit. You provide me the communication and detail in your answers; and I will give you the best grade I can based on that communication and answer.

MAKE-UP POLICY: For Quizzes, there is no make-up, however if the absence is excused, you will receive the same percentage grade on the quiz as you earn on the exam, which covers the same material.

For Exams and Final, make-up is possible, but there is a 10% penalty if the absence is not excused.

For Homework, you must show your work to get credit, half credit for completion and half credit for selected problems. Late homework is worth half credit and will NOT be accepted after one week. You can turn in your homework early if you know you are going to miss the class. You can consult a classmate, a tutor, your instructor, or anyone for assistance on the homework.

LEARNING If you have a learning disability, be sure to discuss your special needs with me

DISABILITIES: during the first week of class. Learning disabilities will be accommodated.

REGISTRATION: · You must register for this class at the Office of Admissions and Records.

· Friday, October 15; Last day to drop the class with no penalty or mark on your

· Friday, November 19; Last day to drop the class and receive a grade of W.

· After November 19, if you are enrolled, you will receive some kind of grade.

TUTORING: Tutors are available at no cost in GMC (The Gateway Math Center) on a drop-in basis, Mon-Fri 9-6.

HOW TO SUCCEED 1. Come to every class meeting, and prepare to learn.

IN A MATH CLASS: 2. Arrive early, get yourself settled and be ready when class starts. Sit where you

won’t be distracted.

3. Read each section before it is discussed in class.

4. Do all of the homework.

5. Start preparing for tests at least a week in advance.

6. Take advantage of tutors and office hours, extra help can make a big difference.

7. Do some review every time you study math.

8. Be willing to ask questions.
