Overview
The round robin system for homework grading gives students the
opportunity to have some problems carefully graded while still
being able to check their work on other problems.
Which problems should a student do
Every student in the class should do every problem listed by the
instructor. Thinking through problems is one of the most important
components in learning mathematics.
Which problems should a student turn in
A student will turn in a problem if and only if it has been assigned
specifically to him or her.
Daily operation
Through the semester, homework assignments will appear on the homework
page for the course. Some problems may not be assigned to anyone specifically
for submission, but most will have initials next to them indicating the student
who needs to submit that particular problem for grading. Everyone tries to
solve the problem, but only one student submits a solution.
When a solution is submitted, the instructor will grade it. If there is
a logical flaw, an omission of part of the argument, or other errors, the
problem will be returned
to the student for revision with an indication of what is wrong, or how
to make progress toward its solution.
The student revises and resubmits the solution. This cycle continues until
the solution is deemed correct.
Once a solution is accepted, it will be posted in a password protected
area on the web for the rest of the class to view. In the process, the
class produces a solution set for the course assignments.
Due Dates
When an assignment is posted, the problems will be given due dates. These
will always be 2 weeks after the date when the assignment is posted.
The due date is the date when the final "perfect" version of the problem is
due. It is not a good idea to wait 2 weeks before making the first
submission; if it has errors, it will not get full credit. It is best to
work on and solve the problem right away and make a initial submission early.
Then there will be time to make revisions and get full credit on a
second, or possibly even a third submission before the due date.
Assigning credit
The presumption is that everyone will work on their assigned problems
until they have them completely correct. However, it helps the rest
of the class more if a correct solution is submitted sooner rather than
later. So, late submissions get partial credit.
Full credit of 10 points is awarded if a correct solution is submitted
by the due date. Partial credit for an assignment which is d days
late is worth
3+7*1.1-d points, rounded to the nearest integer.
Weekends and holidays are not included in the number of days late.
Note, if a correct submission is submitted by the
last day of class, it will be worth at least 3 points.
Submitting assignments
Papers need to be typed and submitted by e-mail as a pdf file. Scanned
documents are not accepted. See here for more information on preparing documents.
Preliminary versions can be submitted on paper in class. However, final
versions need to be submitted electronically.
Getting papers back
If a submission needs revision, it will be returned between 24 and 48 hours
after the submission (not including weekends and holidays).
In particular, papers are never graded on the spot.
Students can verify that their papers have been accepted by checking
their grade through the course web page.
