Course Description and goals:  Math 108 is a special topics course that satisfies the general education requirement for math at the University of Rhode Island.  It introduces the non-mathematics student to the spirit of mathematics and its applications.  The content of the course varies from section to section and semester to semester.

In this section of this course, you will be introduced to some exciting ideas in mathematics that come from a wide variety of disciplines such as voting theory, graph theory, game theory, scheduling, counting, algebra, and fractal geometry. These topics will be presented along with real world applications such as voting schemes, fair division schemes, street networks, planning and scheduling, pattern recognition, and fractals in nature. Three skill areas are addressed, namely, reading of complex texts, use of quantitative data, and writing.

I hope that you will have a better understanding and appreciation for mathematics by the time you finish this course, that you will no longer think that math is only about balancing a check book and designing rockets, and that you will be proud to say that you LIKE math.  You may be surprised to find that taking further math courses is both possible and desirable.

We will use reading, writing, discussion, and world-wide-web assignments as methods of learning the topics covered in this course. You will discuss and work in groups in class as well as do some short presentations. Because of the high level of knowledge that will be imparted and assessed during class time, attendance will be mandatory. During class time, topics will be presented, examples given and then you will be given the opportunity to work examples on your own.

Text: The text for the course is:  Excursions In Modern Mathematics, 5th edition, by Peter Tannenbaum and Robert Arnold.  We will cover the following chapters.
1:  The Mathematics of Voting
3:  Fair Division, The Mathematics of Sharing
5:  Euler Circuits
6:  The Traveling Salesman Problem
7:  The Mathematics of Networks
8:  The Mathematics of Scheduling
11:  Symmetry
12:  Fractal Geometry

Note: There is much more material in our text than we could possibly cover this semester.  Read these entire chapters.  We will cover most of the material in these chapters.

Class work:  Examples and exercises will be worked on in class.  There will be some class discussion and working in groups.  This is a very important time to absorb the information and begin to understand how to apply it to problems.  This work will count as 10% of your grade.  I will collect names while you work in class so that I can count your work toward your grade.  No make-ups are given.

World wide web assignments:  I will use e-mail to send you world-wide-web assignments. These will consist of the names of web sites and questions for you to answer about each site.  You are to visit these sites and respond to my e-mail with your answers to my questions. If you are unfamiliar with "surfing the web", visit a computer lab and ask for help.  Once you get started, you will find that it is a very easy thing to do. To start this process off, as soon as possible, send me an e-mail just saying hello with "MTH108" followed by your full name as the subject. Once I have e-mail from everyone, I will send out the first assignment.  This work will count as 10% of your grade.

Writing Assignments:  Short writing assignments will be given throughout the course.  These are writing intensive and will take quite a bit of time to complete.  Under Homework Assignments below, you will see the specific problems, selected from the text, for each writing assignment.  Follow these instructions carefully:

1)      (5pts) Your header should include your name, writing assignment number, list of problems in this assignment (including the problem numbers and chapter). 

2)      (5pts) Put the problems in the proper order.  Label them and all parts clearly.  Do not include any other exercises.

3)      (5pts) Only use one side of the paper.  Leave room for me to write comments.  Staple together all pages.

4)      (5pts) Write out the entire question and copy any charts or diagrams.

5)      (5pts) Write neatly and follow rules of proper grammar.  Use of a word processor is recommended.

6)      (5pts) Give your solution in paragraph format. You may break from paragraph format to give tables, diagrams, or equations. 

7)      (35pts) Explaining clearly, exactly how you calculated every answer.  Explain it as if you are explaining it to someone who doesn’t know the theory.  Use proper terminology.

8)      (35pts) Emphasis will be placed on correct work and proper use of logic in your explanation.

This work will count as 15% of the final grade for the course.  I will accept these assignments late, but points will be deducted for late work, without exception.

Homework:   Problems are assigned from the book.  You are responsible to do all problems that are assigned.  We will work on some in class and you will hand some in as writing assignments.  It is best if you collect all of your homework in a loose-leaf notebook.  This is so that you can keep it in order and add corrections from class.  Often, one individual problem will take many passes before it is worked up completely correctly.  You must take the responsibility of seeing to it that you know how to correctly answer each homework problem.  Many problems will be presented in class.  Take notes and compare it to what you wrote.  The quizzes will be based on the homework.  If you understand every homework problem then you should have no trouble on the quizzes.

Tutors are available at the Academic Enhancement Center (AEC) in Roosevelt Hall.  AEC tutors can answer questions, clarify concepts, check your understanding, and help you to study. You can make an appointment or walk in anytime Monday through Thursday 10 AM to 10 PM, Fri 10 AM to 1 PM and Sunday 4 PM - 8 PM. For a complete schedule go to, call (401) 874-2367, or stop by the fourth floor in Roosevelt Hall.

Homework assignments:  Begin working on the exercises from each chapter when it is first introduced in class.  There will be some class time allowed for going over some questions on the homework.

Quizzes:   Quizzes will be given based on the homework.  Problems will be selected at random from the homework to demonstrate your understanding of the material. If you miss a quiz, no makeup will be given, instead, the two lowest quiz grades will be dropped and the rest will be averaged to give 15% of the grade for the course.  You are responsible to get from me a copy of the quizzes that you miss.

Exams:   Three exams will be given on the material from the chapters indicated.  The exam questions will be based on the homework questions.  To prepare, make sure you understand homework and quiz solutions.  Solution keys will be given.

Final exam:  The final will be cumulative.  It will cover chapters that were covered on the previous 3 exams, namely, Chapters 1, 3, 5, 6, 7, and 8.

Course schedule:  The following is the schedule of events.  When a chapter is listed, we begin to cover the material in that chapter.  After introducing a chapter, we will used class periods to finish covering the chapter and going over examples and exercises.

Summary of Policies:

Quizzes – There will be no make-ups given unless three or more quizzes are missed due to unforeseen circumstances.  Instead, the 2 lowest quiz grades will be dropped.

Writing assignments – You may hand in any assignment on or before the due date and you may hand it in up to 4:30 pm on the due date.  After that, it is considered late and points will be deducted, unless there are exceptional circumstances.

Exams – You must take all exams during the assigned class period, unless you have made arrangements with me in advance.  If you are sick on the exam date, call my office and leave a message or send me an email, saying that you are sick.  We will make arrangements for a makeup as soon as you are feeling better.

Attendance – I give work in class and it counts 10% toward your grade.  I keep a record of who participates in the class assignments by collecting your names during the assignment.  If you are not there, you can’t do this work, and this part of your grade will suffer. I don’t make any exceptions.
