Required Text:  Elementary and Intermediate Algebra 1st Edition by Mark Dugopolski

 

Optional Text:  Student Manual for Elementary and Intermediate Algebra by Mark Dugopolski

 

Check out the Student Manual for Student Manual for Elementary and Intermediate Algebra  at the library before buying it to see if it fulfills your needs. 

 

Course Description:  This course is a continuation of Math 152A.  I will be presenting factoring, rational expressions, first degree equations and inequalities with absolute value, solving systems of linear equations and inequalities, radicals, rational exponents and their equations, and solving quadratic equations. This course will connect math with the “real” world.  It is my desire to reduce math anxiety and build self-confidence in every student by the end of this class.

 

Prerequisite:  A grade of “C” or better in Math 152A or equivalent or appropriate skills demonstrated through the Math Assessment process.

 

As a courtesy to everyone in class, please turn off all cell phones.

 


 

Students with disabilities must identify themselves to me within the first two weeks of class.

Accommodations for Students with Disabilities: Students requiring accommodations for a certain disability that may affect class performance are requested to schedule with a staff member at the DRC to discuss this during the first week of the quarter so that appropriate arrangements can be made. 

 

 Course materials available in alternate format. 

 

 

My philosophy on Math . . .

            We don’t hear the phrase “Spanish anxiety” or “English anxiety”; why is there math anxiety?  My belief is that if you view math as a different form of language, there is less of an obstacle to learning it.  There are new vocabulary, grammar and rules for every language.   And so with math we have different notation, terminology and properties.  From this new perspective, I hope math will become fluent to all of you! 

            Math is a wonderful tool.  It stimulates our mind to use logic, pose questions, analyze and problem solve!  What other language can do that?!  I hope you come to share my enthusiasm for math and that you may find it helpful in life.

 

The Gateway Math Center has free tutoring for all registered students.  Please Log In and Out

so that the facility gets the funds it needs.

 

 

In this class, it is your responsibility to drop the class in order to avoid an unwanted grade. 

You must go to Admissions & Records.

Friday, September 30, 2005 is the last day for refunds.

Friday, October 14, 2005 is the last day to drop with no record.

Friday, November 18, 2005 is the last day to withdraw with a “W” grade.

 

 

 

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 math statements, and checking and verifying results.


 

Grading:  Your class letter grade will be based on the usual grading scale:

 

A:  90% and above,     B: 80-89%,     C: 70-79%,        D: 60-69%,              F: 59% and under

                        Homework                                            105

                        3 Quizzes (30 points each)                     90

                        3 Midterm Exams (150 points each) 450                               

                        Comprehensive Final Exam:   220

                        Total                                                     865

 

I have given practice problems following each section.  These problems are for you to improve your understanding of the material and to prepare you for quizzes and exams.  Do SOME problems from each group of problems after their lectures.  I do not collect practice problems.

 

Homework:  The Even problems to be turned in weekly are in bold and are due on Wednesdays except HW10**.  Their due dates are listed every week.  These problems are considered late if they are not turned in by 3:00 PM the day they are due.  If you will be absent, either turn in the homework early or have someone turn in the homework assignment for you.  Homework that is turned in late within one week of the due date receives half credit.  Homework turned in after this receives no credit. 

 

Quizzes:  There are no make-up quizzes.   I give 4 quizzes but only 3 are counted.  The lowest quiz score will be dropped.  Each quiz is 30 points.  All quizzes are given during the first 30 minutes of class.  Please be on time.

 

Midterm Exams:  You must notify me before an exam if you will miss the exam (541-4660 EXT 368).  Exams must be made up within 3 school days after the scheduled date, with a penalty of 10%.  You may take an exam up to 3 school days before the scheduled date without penalty.  Arrangements must be made with me one week in advance.

Calculators are not allowed during testing.  Please practice the homework without them.

Comprehensive Final Exam is on Monday, December 5, 2005, 10 – 11:50AM

Note the time:

The Final Exam starts at 10 AM!!!!!!!!

 

Please talk to me if you do not understand my policies.

 


 

Practice Problems that say Odd means do the Odd numbered problems.

EOO means do Every Other Odd problem.
