GENERAL INFORMATION
The purpose of this course is to convey the
power and usefulness of mathematics as illustrated by a variety of problems
that can be modeled and solved by mathematical means. Some of the topics we will cover are
probability, consumer mathematics, graph theory, and voting and apportionment.
For my part, I will be working to deliver
informative and interesting class activities and presentations. Every
class regardless of the format, lecture, computer lab, discussion, or your
presentation will require time, effort and planning on my part. For your
part, it will require time, effort and planning – sound familiar?
To take
charge of your own education, you must be willing to spend time working through
the problem material. The key to success in this course is the problem
material. It is very important that you try all the assigned problems.
The problems assigned for each textbook section indicate what I feel is
important in that section and which ideas and skills you should focus on. I
expect each and every student to be an active participant in the class
activities
Attendance and Classwork:
You are expected to attend every class.
We will be
spending time during each class working on problem material. The work done in this hour will be corrected
each week and count as 10% of your final course grade.
Homework assignments will be posted on the website: www.ric.edu/scosta.
You should attempt to solve all of the problems on the suggested problem
list. You are encouraged to work in groups with other students in
the class in solving the problems. Be sure to ask questions on the
problems you have trouble with as they may appear on exams.
Evaluation:
Your grade will be determined by
your work on weekly assignments (10%), 3 inclass exams (20% each), a final
exam (15%), and quizzes (15%).
You need to inform me in
advance if you cannot make the exam. Makeup exams will be given to
students who have a legitimate reason for missing an exam. It is not
acceptable to miss an exam and call me the next day with an explanation of why
were not at the exam.
Any student with a documented
disability is welcome to contact me as early in the semester as possible so
that we may arrange reasonable accommodations. As part of this process, please
be in touch with Ms. Ann Roccio, coordinator of
services for students with disabilities at CraigLee 125, 4568061
