Instructor:  Karen Mortensen, 247 Illini Hall, 244-4128, kmortens@math.uiuc.edu  

 

Times:  Monday, Tuesday, Wednesday, Friday 10:00-10:50 in 143 Altgeld Hall.  All students in this course should plan to attend all class sessions.  This course is not suitable for self-study.

Office hours:  Thursdays 10-11, Fridays 1-2, in 247 Illini Hall.   See me for an appointment if those times are not convenient.

TA:  Ioannis Konstantoulis

Required Text: John P. D'Angelo and Douglas B. West, Mathematical Thinking: Problem-Solving and Proofs, 2nd Edition, Prentice Hall, 2000.

Prerequisites: Calculus II (Math 231 or the equivalent) and completion of the campus Composition I general education requirement.

Goals: This course prepares students for work in upper division mathematics courses by teaching selected fundamental topics from discrete and continuous mathematics, problem solving, techniques of proof, and clear mathematical exposition. Central goals of the course are to help students learn to read, construct and write mathematical proofs and to help students understand the structure and conventions of written mathematical arguments. Clear mathematical writing and clear mathematical thinking reinforce one another; for this reason, much attention will be given to the writing of mathematics.

Notes: Math 348 does not count towards a Mathematics minor.  If you have already succeeded in 400-level courses which require the writing of proofs, then Math 348 is not the course for you!  In this case, please choose another course to satisfy the Advanced Composition requirement.

Semester Schedule (subject to change- the chart below gives as idea of what we'll be covering, but some sections may be omitted):
 

Class Meetings (MWF)

Topic

Assignments: Homework will be assigned each week in lecture and will usually be due on Monday. It will be graded and returned. Homework assignments will consist primarily of writing mathematical arguments and proofs; the validity of the mathematical reasoning and the quality of the exposition will both count toward the grade. You are welcome to use any resources you like, including talking to one another. However, the more you can do on your own, the more you will learn. I strongly recommend that you put in some real work on a problem before consulting with anyone else. Also, each person must write up the work independently; doing otherwise will be considered plagiarism.

Additional writing assignments will be assigned in the weekly lab. See the summary below and the attached sample writing assignment for more details.

Topics for Friday Math 348 Mathematical Writing Sessions (subject to change, but the schedule should at least give you an idea of the sorts of things we'll be doing.
 

Week 1
Aug. 28
Introduction to Mathematical Writing.  Resources, TeX, LaTeX (mathematical word processing programs).

Week 2 Sept. 3

Mathematical Writing exercises.

Week 3 Sept. 10

Peer review of written work. Students will work in groups, presenting their mathematical work and giving one another feedback on written drafts of the work. After the session, students will revise their drafts before submitting them.

Week 4 Sept. 17

"Rules" of mathematical writing. Students will discuss the conventions of mathematical writing in various settings and compare these to the conventions of other types of writing.

Mathematical notation. Students will read and compare sample passages containing mathematical notation. Discussion of how the choice of mathematical notation affects the clarity of the writing.

Week 5 Sept. 24

Peer review of written work. See Week 3.

Week 6 Oct. 1

Peer review of written work.  See Week 3.

Week 7 Oct. 8

Peer review of written work. See Week 3.

Week 8 Oct. 15

Audience exercise. Students will compare several passages, all on a single mathematical topic, written for different audiences.

Week 9 Oct. 22

Peer review. Students will bring to class a draft of an article written for a general (e.g. newspaper-reading) audience. In groups, students will discuss the drafts and give one another feedback. The students will subsequently revise the drafts for submission.

Week 10 Oct. 29

Peer review of written work. See Week 3.

Week 11 Nov. 5

Peer review of written work. See Week 3.

Week 12 Nov. 12

Peer review of written work. See Week 3.

Week 13 Nov. 19

Peer review of written work. See Week 3.

Week 14 Dec. 3

Paper-length writing. Students will discuss the conventions of mathematical writing of article length, having analyzed several examples in advance. This session will include practice in writing an abstract.

Week 15 Dec. 10


 

 


Excused Absences: Acceptable reasons for excused absences are significant illness, family emergency, or University-sponsored travel. Whenever possible, you must notify me in advance, preferably in writing (email is good). In case of emergency, notify me as soon as possible. The University is advising students with flu symptoms (fever, cough and body aches) to stay home until 24 hours after the fever is gone.  I encourage all students in Math 348 to follow this advice. For more information, see http://www.mckinley.illinois.edu/general/news/h1n1_update.htm

For an excused absence, you will be able to either make up the work or be excused from it - this is left to the instructor's discretion, depending on the circumstances. For any foreseeable absence, the make-up work must be done in advance of the due date.

Exams: There will be three hour exams (Mondays Sept. 21, Oct. 19, Nov. 16) and a comprehensive final exam (Mon. Dec. 14, 8:00-11:00am).  Notes and books may not be used on exams. You can use a calculator on exams. Because of the nature of the material, a calculator is unlikely to be of much use, however.  The final exam will cover the entire course. Please arrange any travel, etc., so that you can take the final on this date. Math 348 has a non-combined final exam. There will be no conflict exam given except for those few individuals who meet the official university criteria given in the student code http://admin.illinois.edu/policy/code/article3_part2_3-201.html

 

Missed exams: If you miss an exam, you will receive a 0 for your exam grade. The only exception is if you have a valid excuse for missing, such as a significant illness or a serious emergency. In this case, you must inform me before the exam, or, if this is physically impossible, then as soon as possible afterwards. In this situation, you will be given a make-up exam as soon as possible.

Grading: The course grade will be determined by

15% Exam 1

15% Exam 2

15% Exam 3

20% Final Exam

15% Homework

20% Additional Writing Assignments (including participation in the peer review process)

General Education Credit: This course fulfills the Advanced Composition general education requirement.
