Course Description: Standard methods of solution for elementary ordinary differential equations. Students must meet the prerequisite or be concurrently enrolled in MATH 323.

Course Objectives and Student Learning Outcomes:

Attendance:  I do not take attendance.  However, I would strongly discourage you from missing any classes.  I rarely have students even pass the course who do not come to class nearly every day.  Even those that do manage to pass do not receive the best grade that they are capable of earning.  Think of someone who works as a consultant.  They don't have to go to work every day because there is no boss keeping track of them.  But they won't get paid unless they complete all the work by the time scheduled in their contract.  When I was a freshman, I quickly discovered that if I missed a one-hour class where I knew what was going on, it took me 1.5 hours to make up the material.  The ratio was much worse if I didn't know what was going on.  I suspect similar ratios are true for most people.  It is simply more efficient to just go to class and hear a lecture and talk to classmates (who are often just as confused as you) than to skip class and try to learn it all on your own.

I give makeup exams rarely and only with valid, documented reasons that are given as soon as reasonably possible. In particular, this means before the exam.  This also means that I assume that if you are sick enough to miss the exam, I assume that you are sick enough to go to the student health center.  The health center can provide you with a signed and dated note saying that you were seen by a doctor (I do not need to know what you were seen for).  The documentation should be consistent with the excuse (health center note for illness, police report for a car accident the morning of the exam, funeral program or obituary for a funeral, etc.).  Makeup exams will not be graded until the documentation has been submitted.  In addition, all makeup exams are given on Study Day.  This semester, Study Day is Wednesday December 12.  Vacations and other family or personal reasons will not be considered a valid excuse for missing an exam unless you inform me of the absence by Wednesday September 5.  Any such events that are not yet scheduled are expected to be scheduled around the exam dates, which are given on the Test Dates page.

There are two types of collected homework assignments - basic ones, and more involved ones.  The basic assignments will mostly be book problems.  The more involved assignments will be announced in class.  Each basic assignment will be worth 10 points, they will not be accepted late, and I will drop about 20% of them.  The exact number of dropped basic assignments will be announced after Thanksgiving.  The point value of the more involved assignments will be announced when the assignment is given, and will be more than 10 points.  None of the more involved assignments will be dropped.  If a more involved assignment is submitted late, it will be subjected to a 25% per weekday penalty (so submitting it on Wednesday when it was due on Monday will result in at most half credit).

The due time for all assignments is 3:00 pm on the day due or when I start grading, whichever is later.

Homework assignments may be submitted early if you know you will be gone on the due date.  They may also be submitted by a friend/spouse/roommate/etc., who may slide them under my office door (MA 375B).

Academic Honesty: You are expected to do your own work.  You may certainly work with others and get help on homework assignments, but the work you submit should be your own work.  Note that during exams you will not be allowed to get help from others.  Make sure that you learn the material while you do the homework - that is the purpose of the assignments.  Then during the exam you can demonstrate your knowledge - that is the purpose of the exams.  Cheating and plagiarism will not be tolerated in any college course (or any course at any level).  See the MSUM Academic Honesty policy for more information and possible consequences of cheating.

Special Accommodations: Students with disabilities who believe they may need an accommodation in this class are encouraged to contact Greg Toutges, Director of Disability Services at 477-4318 (Voice) or 1-800-627-3529 (MRS/TTY), Flora Frick 154 as soon as possible to ensure that accommodations are implemented in a timely fashion.  Information regarding Disability Services is available at http://web.mnstate.edu/disability/

Course Requirements:  You are expected to complete daily homework (both suggested and collected), complete and submit the worksheets, and take and pass all the exams on the scheduled date.

Evaluations Standards: Your course grade will include worksheet and exam grades.  For more details, see the grade page.

Course Outline:  See the course schedule for a week-by-week outline.  A topic outline is below.

Calculators:  A scientific calculator will be expected for this course.  I will allow graphing calculators.  We will on occasion use Maple as well.

A basic scientific calculator costs $15-$20 at Target, Kmart, Office Depot, or some similar store.  Many students like one that has a two-line display (one line where you type and one line where you see the answer) and a key labeled "ANS" (which may be a second function on the negative key).

Regardless of your calculator, you must show work to receive credit.  I grade the knowledge and understanding of Differential Equations that you possess, not that which your calculator or software possesses.  That knowledge and understanding is measured by the work that you show, not by the answer that you give at the end.

General Comments:  For all graded work in this class, you must show work for credit and give exact answers.  In general, if you have to write it down, you have to show it to me.  My rule of thumb when grading is either whether I could do a similar calculation in my head and not make a mistake or if the point of the problem is being met (i.e., if the point of the problem is to show a known result, you will have to show it in some detail).  If I feel that you needed to show more work, I will indicate it.  My criteria is the same for both worksheets and exams.

I do not curve.  I grade each student individually against a standard of whether or not you personally have mastered the material, not by comparison to other people.  I also very rarely give extra credit, and when I do it is to the entire class.  If you come to my office at the end of the term and ask if you can do extra credit to improve your grade, my answer will be no.  The grading scale and weights for the homework and exams are given here.

I will in general return any work the next class day.  If you are not there, I will not give it to friends, nor will I give out grade information on the phone or via email.  (These restrictions are not arbitrary - they are based on federal law regarding student privacy.)  Normally, I include any old assignments with any current ones, but I do not try to pass them back a second time unless you have turned in the most recent assignment.  I will bring the old assignments with me every day, so if you ask at the end of class you can get them then.

I expect you to be responsible for yourself as far as getting notes from a classmate if you miss class.  (My notes rarely have answers, just problems, so are not very useful to students.)  I also expect you to turn in any homework early if you know that you will miss class.  This includes those instances when the absence is due to an official university activity.

Cell Phones:  Turn off your cell phones when you go to class (this class or any other class).  Cellular phones and other distracting devices generally have no place in a formal or semi-formal setting, such as a classroom.  If your phone rings audibly during class, I reserve the right to require you to leave the classroom for the remainder of the period.  I will likely exercise this right if your phone rings during an exam.  Hence, if your cell phone rings during an exam, you will have to turn in what you have completed up to that point.  No extra time will be given.  I strongly suggest that you always remember to turn off your phone.  (You are free to return to class the next day, and there will be no other consequences.) 

In addition, during exams, your cell phone (or any other electronic device other than a calculator) may not be visible at all - you must put it in your closed bookbag or something similar.  If you use it for your watch, you will have to bring a different clock to exams or use the classroom clock.
