Information about Math 5

In the following paragraphs, you will find the most important facts about the structure of the course: for example, when and where it meets, the name and office hours of the instructor, the course requirements, dates and times of the exams, and the Academic Honor Principle as it applies to the course.

Textbook: Mathematics and Knowledge: Models of Reality, draft manuscript by Dwight Lahr. The text is available at Wheelock Books.

Undergraduate Tutor/Grader:
Mia Wiegand
Tutorials will be held by Mia Thursdays 7:00-8:00 in Silsby Room 113 to assist you with the homework (especially that due the next day) or other math being covered.

Class Meetings: MWF 10:00-11:05 in Kemeny 105 (x-hour Th 12:00-12:50)

Homework: Our homework grader is Mia Wiegand. Each day exercises will be assigned that are intended to give you facility with the concepts being developed in class. All material will be covered in class, and you should be able to do the exercises listed for that day after having attended the class. Every Friday a selection of homework exercises from the week will be due in class; you will hand these in for grading by Mia. Also, each Friday the homework assignments for the next week will be posted on the course website at

Class Discussions: Each student will be expected to participate in the class discussions, especially those that occur on Fridays. Also on Fridays a group of about three students will make a 20-minute presentation on some famous mathematitians and their work in relation to real world mathematical problems and issues. Specific topics will be assigned during the first week. The students making the presentation should develop three to four questions that will be used to focus the discussion of the class following the presentation. The Friday discussions will also provide a good opportunity to review homework exercises assigned in that week.


The Final Paper: a seven-page double-spaced research paper on a mathematical application in the everyday world. All papers must contain at least 20% mathematics, involve mathematical ideas, and develop material that goes beyond what is covered in class. You should begin thinking about that paper from the first day of Math5, though you probably will revise your ideas as we go along. You might want to discuss your ideas with your instructor.

The weekly group presentations: Each student will participate in one formal group presentation, but all students are expected to attend all presentations. A grade will be assigned to each student for his/her oral group presentation based on the following categories (see below under "Grading" for overall point totals):

Library Resources: Ann Perbohner, Reference/Bibliographer for Mathematics and Computer Science, is putting together the website m5w12 guide to doing library research, a colledtion of library resources especially for our class. Check it out even as it is being updated.

Grading: Final grades for the course are determined primarily on the basis of performance on the course requirements. However, a student's contribution to class discussions will also be taken into account in the determination of the final grade. The formal weightings are reflected in the following point-scheme:

Total Points: 250

Precise letter grades that take into account total performance will not be assigned until the end of the course. However, after the mid-term, you will be given enough guidance to determine the approximate level of your overall performance relative to a three-point scale such as "excellent, satisfactory, unsatisfactory." Feedback will also be provided on your contribution to class discussions.

Academic Honor Principle:
On exams: No help is to be given or received.
On homework, papers, or oral presentations: No copying. You may seek help from anyone associated with the course, or from a librarian, as much as you need. You may work with other students except on exams, but must always write up whatever you are working on on your own. Copying from someone else's work, including the sharing of electronic or other files (except among group members in oral presentations), is not permitted and is a violation of the honor principle.

Students' Religious Observances: Some students may wish to take part in religious observances that occur during this academic term. If you have a religious observance that conflicts with your participation in the course, please meet with your instructor before the end of the second week of the term to discuss appropriate accommodations.

Flu or Another Serious Illness: If you contract a flu or another serious illness, please contact your professor by email. I will be happy to make arrangements for you to make up late work, or exams if you provide me with a note from Dick's house. Please do not come to class if you have a flu or an influenza-like illness. The Math 5 website will contain the complete class schedule, so you will know what you've missed. For more information on what to do if you believe you the flu, see the Dartmouth web page devoted to this topic.

Disabilities: We encourage students with documented disabilities, including "invisible" disabilities such as chronic diseases, learning disabilities, and psychiatric disabilities, to discuss possible accommodations with your instructor. Students might want to consult as well Student Accessibility Services, 301 Collis Center, ext. 6-2014. In addition to providing information and services, the office can assist with determining appropriate accomodations and registering them.

Math 5 Website: We have a website that organizes the materials of the course. The address is There you will find all the handouts of the course, as well as the homework assignments.
