Grade will be reduced one letter if fewer than 90% of Maple-TA assignments are completed adequately. 

Homework Policy:

With few exceptions, you will have two assignments due each day, both listed on the class Moodle  page (login with your stolaf e-mail name and password at http://moodle.stolaf.edu/).

A reading/Maple-TA assignment covering the material to be discussed during that class period. For each reading assignment, you are to read the section carefully, identifying the main concepts and questions you may have.  Then you will complete a short Maple-TA question set to help you identify what you understand and where you may need additional explication. Your reading assignment is a very important part of the your work in this class, and the Maple-TA question sets are required work.  You must complete each Maple-TA (on the web) no later than 6 a.m. of the following class day.   Maple-TA assignments are graded only on completion, not on correctness.  You must complete at least 90% of the Maple-TA sets, or your course grade will be lowered by one letter grade.

A writing assignment based on the material discussed in the previous class as well as often some preview problems from the next sections and possibly some review problems from previous sections. This assignment should be done in draft form by the next class day to allow for a small amount of explication in class. The final form of each assignment is due on the second class day after it is assigned. You are encouraged to work with other class members to do your homework assignments, and may if you wish, submit one paper for two people. (If you do this, be sure to put the names of both contributors on the paper and take turns writing the final draft so that you both get your writing critiqued.) The writing assighments will be corrected and the grades will count toward your final grade in the course.

No late homework will be accepted, but 3 lowest  homework scores will be dropped when computing homework average.

Computer Labs:
During the semester, we will have 6-8 computer labs (see the Tentative Syllabus for the current lab schedule) and some computer compontents of other assighments. These labs use the computer algebra system Maple 10 . This program is available on the computers in SC 175 and OMH 108.   Some of the tests may have a take-home portion on which you will be expected to use Maple.  (If you want Maple on your own computer, check the class Moodle page for information on purchasing a student edition.)

Disability Policy:
If you have a documented disability that will impact your work in this class, please contact me to discuss your needs. Additionally, you will need to register with Student Disability Services located at the Academic Support Center in Room 1 of the Old Main Annex. All such discussions will be confidential.
