Attendance is essential.  You are adults and mature enough to realize that in order to succeed in this class it is vital that you be here.  If you cannot make it to class and have any questions, contact someone in the class or myself.  You are responsible for all information given during class.  Missed quizzes and exams may be made up if and only if you contact me before the quiz or exam and have a legitimate excuse.

Cheating will not be tolerated.  First offense will be a zero for the particular work; a second offense will result in an F for the course.

Responsibility:

My responsibility is to help you learn the material in this class through presenting new concepts, modeling the process of solving problems, and challenging you do your best.  I will do this to the best of my ability.

Your responsibility is to be actively engaged in the process of learning through attending class, reading the text, listening attentively, taking notes, practicing the concepts through doing daily assigned homework, asking questions when you need clarification, and seeking outside help when you need it.  You will not succeed in this class if you are unwilling to put time into practicing the concepts outside of class.  I encourage you to study with others and to seek a tutor if you find the material very difficult.

You are responsible for all information and assignments given during class, even if absent.

Americans with Disabilities Act:

If you are a person with a disability and require any auxiliary aids, services or other accommodations for this class, please see Wayne Wojciechowski in Murphy Center, Room 320 (796 - 3085) within ten days to discuss your accommodation needs.

Assessment:

Grading scale: A - 91%, AB - 88%, B - 81%, BC - 78%, C - 71%, CD - 68%, D - 60%.

Chapter Exams:  (30%)

Assignments:  (30%)

Individual and group assignments, for grade, will be given throughout the semester.  Group assignments are to be completed as a group.  Every member of the group will receive the same grade.  If a member of your group is not pulling his/her weight contact me.  Any student who does not actively participate in completing group assignments may be asked to complete them alone.  Journal assignments: I will assign a number of related writing projects during the semester.  I will collect and read your journals twice - at mid-semester and at the end of the semester.  Journals will be graded on accuracy, completeness, thought put into your responses, and writing skills.

Quizzes: (10%)

Quizzes will be given at least once a week, with the possible exception of exam weeks.  You will have a quiz the last day of every week (usually Friday).  A pop quiz can occur any day of the week.

Final Exam:  (30%)

Your final exam grade will consist of a take home group, open book, exam and a comprehensive individual, closed book, exam given on Wednesday Dec 8 from 12:50 to 2:50 PM.  The two will be combined to form one exam grade as follows: group exam (1/3), individual exam (2/3).

Late Assignments will be accepted up to three days late.  For each day late your grade will be deducted 10 percentage points (one grade level).  After three days a zero will be given for that assignment.  Any extra credit assignments will not be accepted late.

Extra Credit assignments may be offered during the semester.  Extra credit assignments are not accepted late.  Extra Credit is graded on a point for each problem correctly done and the points are added to your quiz scores.  Extra Credit will not raise your grade more than one half grade level.  I.e. it can raise your grade from a BC to a B but not from a C to a B.

Missed Quizzes and Exams: Missed quizzes and exams may be made up if and only if you contact me before the quiz or exam and have a legitimate excuse.

Schedule:

This schedule may change as we progress through the course.  You will be notified of any changes.  You are responsible for knowing these dates.  Graded assignment due dates will be announced as they are assigned.
