It is strongly recommended that you complete all five modules before enrolling in either Math 152A, Basic Algebra (Part I) or Bus 112, Business Math.
In order to receive credit for a Module, a student must register for it at the office of Admissions and Records. This must be done by Monday, November 23. If you register for a module and then are unable to complete it, you must drop the module by Monday, Nov. 30. If you do not drop the module, the instructor is required to give you a grade.
Students may either begin each class with a lecture and the rest of the class time will be for students to work individually or the students may work at their own pace requesting assistance as needed. Lectures will be presented following the time line listed at the end of this syllabus. Students are encouraged to read in advance the material covered in each lecture.
METHOD OF STUDENT EVALUATION:
Homework must be completed and turned in before an exam is taken. The required homework is all of the work for: 1)The Set I Exercises for any section covered in the particular chapter 2) Set I Exercises for all of the Review Sections 3) The Diagnostic Test. If a homework set is turned in incomplete, 10% will be deducted from the grade for each section that is not complete. This means that if three sections are not completed, then 30% will be deducted from the grade for that chapter. ANY WORK THAT IS DONE MUST BE INCLUDED AS PART OF THE HOMEWORK WHICH IS TURNED IN.
Examinations are given at the end of each chapter. If the student does not receive a score of at least 70%, he or she will be asked to take another test after corrective action. If a student does need to take a second test, the highest score possible for that chapter is 70%. If there is one chapter in a module, the grade on the chapter test will be the grade in the module. If there are two chapters in a module, the average of the two chapter tests will be the grade for the module. EACH MODULE RECEIVES A SEPARATE GRADE. Grades are based on the following scale:
A 90% - 100% B 80 - 89% C 70 - 79% D 60 - 69%
A student must obtain 70% or higher before he or she may proceed to the next module.
OFFICE HOURS: Room A204 page 3
Monday, Wednesday & Friday 12:30 - 1:30
TUTORING: Individual math tutoring is available in the Mezzanine area just outside of the library. If you are having trouble finding a math tutor, check with the personnel in room B107. Tutoring hours are posted outside of B107 and in your classroom.
CALCULATOR: A calculator may be used in Module D.
LEARNING DISABLED STUDENTS: If you are in the Learning Disabled Program, please speak with one of the instructors about your special needs. It is also important that one of us speak with anyone for whom math has always been extremely difficult.
HOW TO SUCCEED IN A MATH CLASS:
1) Come to every class meeting.
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) Do some math every day.
6) Start preparing for tests at least a week in advance.
7) Take advantage of tutors and office hours, extra help can make a big difference.
8) Do some review every time that you study math.
