Math 207 is a multi-section course with a course coordinator. The course coordinator decides all details of the course (material to be covered, exam dates, percentage of the grade determined by each exam, etc.) Thus, all the instructors will have identical policies. These are described in the Math 207 Common Syllabus. For convenience, I have also put them into this web page.
For this semester, all sections will have individual exams during the semester, but a common final exam. The exams in the various sections will be similar to each other, but not identical, since they are given at different times. All exams, except for the final, are on Fridays during class time.
I don't use the gradebook in either MyLab or Canvas. Instead, I will post a spreadsheet in Canvas after every exam. The students who don't come to class to pick up their exams will not have their scores posted. They will have to come to one of my office hours to find out how they are doing.
The common syllabus does not go into details about make-up exams very much, so let me spell that out here. In all cases, it is expected that documentation will be provided if requested, and in the case of a foreseeable conflict you contact your instructor beforehand, not afterwards. Chances are that if you are gone on a Friday only, your make-up exam will be the day before.
There are 3 situations where the instructor is required to give a make-up exam. They are
- Court appearance (whether you are plaintiff, defendant, or jury member)
- Military assignment (including ROTC)
- Being an official representative of Iowa State University. This includes being on an official sports teams supervised by the Athletic Department, being in the marching band, giving a talk at a conference as part of an ISU research group, testifying to the legislature as a student representative, and similar things. It does not include participating in a soccer tournament if the soccer club is just a student club, not ISU Athletics.
There are 3 further situations where the instructor is encouraged, but not required, to give a make-up exam. They are
- Medical excuse. This comes as a surprise to many students, but the instructor is actually not required to proved a make-up exam if you are sick. Of course, this will usually be granted.
- Family emergency. This includes things like a parent dying or having a serious medical problem, parents divorcing, family home burning down, etc.
- Religious excuse. If your religion has a significant holy day on the day of an exam, you can request a make-up.
And, of course, there is the catch-all situation where you simply ask your instructor for a make-up for an event that does not fall into these categories. For example, a job interview, a wedding, a non-official competition. What is definitely NOT in this category is "I want to leave early for spring break or at the end of the semester".
Lay - Linear Algebra, 5th Edition
Students also need to purchase an access code for MyLab, an online homework system from Pearson Publishing. MyLab contains an electronic copy of the textbook.
If I understand the description of the Immediate Access Program correctly, it works like this: you can sign up for this program (follow the instructions in the link above), and the cost of MyLab will show up on your U-Bill. If you drop the course within 10 days, you will get an automatic refund. Also, after a couple of weeks you can get a loose-leaf version of the textbook if you want (for extra cost).
Alternatively, you can buy the book separately (if you want), or the access code to MyLab separately, but then you can't get a refund if you drop the course. If you are repeating this course and have bought MyLab access before, you will not need another code.
A scientific calculator is required for this course. Also, if you wish to purchase a simple graphing calculator, it would be helpful for many problems.

Individual assignments will not be curved in the course. However, at the end of the semester, there will be a final curve for each section of MATH 207 individually. After instituting the curve, the median score in the section should be a C+. Also, final grades weighted according to the scale given above will be no worse than if they were measured on a 10% per letter grade grading scale, with the plus or minus grade at the top or bottom 3% of the range respectively. (e.g. 90%+ =A, 80%-89.99% = B, etc.)
You are required to come to class every day, however you are not required to notify us for a class absence. If you are unable to attend any of the unit exams or the final exam due to an emergency, you MUST provide written documentation of the event before an alternate exam is administered (e.g. if you are sick, get a note from a doctor). If the conflict is foreseeable, you are required to inform the instructor beforehand, not afterwards. Your make-up exam may occur before the scheduled date in this case.
Please silence all mobile devices before the beginning of class (if you must take an emergency call leave the classroom discreetly). Do not utilize any mobile music device while in class, it tends to distract other students and shows an extreme lack of respect.

If you need extra help in any aspect of this course, you have several options – some are better than others. First and foremost, come to either instructor’s office hours regularly and ask questions. If you cannot make it to our office hours, send us an email and schedule an appointment. We will make every possible effort to find a time to help you. You can also send short questions via e-mail. Other resources should be utilized as much as possible, you can link to their page from here: https://www.asc.dso.iastate.edu/resources.
The following is a proposed schedule of events corresponding to a fifteen week course with homework due for each chapter on the Pearson online homework system MyLab Math (previously named MyMathLab) and three unit exams. Time can be made for in class quizzes or out of class quizzes on MyLab.
