Texts: Analysis With and Introduction to Proof, fourth edition by Steven R. Lay.

Course Webpage: I will maintain course information at the course webpage whose URL is http://www.gac.edu/~karl/courses/mcs220/07s/. There you will find a complete schedule, course description, current homework, readings, and so on.

Classes: Classes will be used for discussions, problem solving, lectures, and other fun activities. You should prepare for classes by doing the reading beforehand, thinking about the problems in the text, and formulating questions of your own. You should also participate as much as possible in class. Class meetings are not intended to be a complete encapsulation of the course material. You will be responsible for learning some of the material on your own.

Absences from class: Attendance, both physical and mental, is required. Should you need to miss a class for any reason, you are still responsible for the material covered in that class. This means that you will need to make sure that you understand the reading for that day, that you should ask another student for the notes from that day, and make sure that you understand what was covered. It also means that if we had an assignment that we did in class that day, you will get a 0 for that assignment. If there is an assignment due that day, you should be sure to have someone hand it in. You do not need to explain why you missed a class unless there is a compelling reason to do so.

Should you miss what I consider to be too many classes, I reserve the right to reduce you course grade accordingly.

Reading: I hope to cover sections 1-23 (except for sections 9 and 15), and sections 29-31 of the text, which means that each section will take, on the average, two class days. I will keep the reading assignments on the Schedule of classes, reading, homework, exams, etc link, which is also visible from the course homepage.

Homework: Homework is an essential part of this course - as you can see below, it accounts for 40% of your course grade. I will assign you three kinds of problems:

• Routine exercises: These will be problems (like those on the first homework assignment) that do not require a formal mathematical write-up, and will typically be more computational in nature. Nonetheless, I will expect that you do these problems neatly and use full sentences for the explanations you give. These problems will occur less frequently as the semester progresses.
• Writing problems: These problems will require a formal mathematical write-up. I will devote a considerable amount of class time to demonstrating what I mean by a mathematical write-up; briefly, it involves a logical argument using complete sentences and a minimum of mathematical symbols. I will designate a problem as a writing problem by putting a W beside it.
• Mastery writing problems: Mastery problems are graded as either "mastered" or "not yet mastered." Each mastery problem will be given two due dates: the first one is when your initial attempt is due, and the second is when the final attempt is due. If you submit an attempt by the initial due date, then you may re-submit attempts for that problem up until the final due date for that problem. For those not yet mastered, I may write some brief indication of what area needs work, but you should really take this as an invitation to come talk. Your grade on mastery problems will be based on what percentage of the problems you finish.

Working together: I encourage you to work together in this course. However, I have three rules regarding this:

• You may discuss the non-mastery writing problems, but you must write them up entirely on your own. However, I strongly encourage that you try to do them on your own as much as you can, since it is important for you to know how to do them on your own.
• Mastery problems must be done entirely on your own, though you may of course discuss them with me.
• Exams are to be done entirely on your own.

Exams: We will have a total of four exams: three during the semester, and one during the scheduled final exam time. In order to allow you enough time to do these exams, I will do them in a "check-in/check-out" manner, giving you two hours to do them.

Academic Integrity: In this course, you are expected to to adhere to the highest standards of academic honesty, to uphold the Gustavus Adolphus College Honor Code and to abide by the Academic Honesty Policy. Copies of the honor code and academic honesty policy can be found at the Academic Information and Policies web page.

You will be expected to sign the honor pledge on every homework problem or problem set and on the exams. See the heading Working together (above) for my rules on working together.

A first violation of the honor code will result in a grade of 0 on the assignment in question. Any further violations will result in a grade of F for the course. In all cases, I notify the office of the Dean of the Faculty.

Course grade: will provide you with a grade on each assignment and exam, so that you may keep track of your performance. As a guideline, the components will contribute in the following proportion to the final grade:

Accessibility: Please contact me immediately if you have special physical circumstances, e.g. impaired vision, which may affect the accessibility of any course components. I will do my best to facilitate necessary arrangements or resources.
