MATHEMATICS DEPARTMENT ATTENDANCE REQUIREMENTS

DEFINITIONS:

ABSENCE - failure to be present for a scheduled meeting of the class or arriving for the class more than ten minutes after the scheduled time for the class to begin.

TARDY --- arrival to class after the instructor has called the roll and before ten minutes past the time scheduled for the class to begin.

I.   Absences are counted from the first day of classes.

II. Five absences are allowed for a class that meets three times per week, and three absences for a class that meets two times per week.

III. Three tardies are considered as one absence. The student must meet with the instructor at the end of the class to which he has been late to have the absence changed to a tardy.

IV.  There are no "excused" absences; all absences are counted, regardless of the reason for the absence.

V.   A student missing class time by leaving early will also be counted absent.

Please note: You are responsible for all material and announcements presented, whether you are present or absent.

MAT 168 COURSE OBJECTIVES

Students should be able to:

1.   Understand the basic ideas and techniques of geometry and      trigonometry (no proofs).

2.   Apply mensuration formulas to geometric figures.

3.   Understand the application of basic algebraic techniques to geometric situations.

4.   Solve problems by identifying what information is available and relevant to the problem.

5.   Solve problems by selecting or developing appropriate procedures and relationships.

6.   Solve problems by correctly applying the methods selected to the information available.

7.   Solve problems by verifying the validity and appropriateness of the solution.
