Homework Grading Outline
Homeworks are posted every Wednesday and are due the following
Tuesday. There will be 9 homeworks in total. Each homework will
consist of about five problems, and each problem will be assigned to a
team of about three students.
Here is an outline of what happens during each grading cycle. The
grading cycle for each homework starts the Wednesday the homework is
posted to class, and ends on the day the graded homeworks are handed
back to the students (this will be the Monday after the week the
homeworks are due).
The graders will get points for their grading effort, based on the
quality of their work. These will count for 5% of their total score
for this course.
- Wednesday: Right after the homework has been posted,
students may volunteer by email to
for grading a particular problem. It
may be advisable to volunteer at the beginning of quarter, when
workloads are lighter.
You can volunteer as a team (of about 3 students) - in that case your
email must have the names and email address of all members of the team
- or as an individual. We will combine individuals or groups of 2
into a team when needed. You can volunteer for a particular problem,
or for any problem, meaning that we choose for you. You can
specify a second, third, etc, choice in case your prefered problem has
been given to others already. Also say whether your last choice is
"any" or "none".
You may put yourself, or your team, on a waiting list for a particular
homework cycle before the assignments are posted; in that case you
need to confirm by email (and possibly choose a problem) on the
Wednesday soon after the posting of the assignments.
We will answer grading requests only on (or around) Wednesdays.
There appears to be a long waiting list forming, and we will use the
time of first posting to cs154grading@cs to decide who gets to grade first.
As soon as the positions are filled we tell the volunteers whether or
not they have been selected, and for which problem. Each team gets
assigned a supervising TA.
The team members solve the assigned grading atom and submit their
solutions to the supervising TA, who will grade them. Collaboration
between members of the same team is allowed for this purpose. When the
solutions are not perfect, team members should communicate with the TA
or each other until a thorough understanding of that problem is reached.
In a worst case, a member can withdraw from the team if such
understanding cannot be reached.
- Monday: The team should have combined their solutions and
the feedback from the TA into a model solution, in a form suitable for
posting on the web (latex, postscript, plain text, a scanned picture,
etc.). When necessary, the team meets with the TA to fine-tune the
model solution. Default meeting time with TA: after class. In case
the team submits a totally acceptable solution by email, a meeting may
not be needed.
- Tuesday, 5pm: Team collects homeworks from the boxes in the
Gates 4B stairway.
Team members make a first pass over the homeworks, annotate homeworks
extensively without assigning points and note down partial
credit cases. Use a red pen (or a color different from the student's
work) to write comments (legibly!) explaining the student's mistakes.
The team also meets to fine-tune the model solution based on grading
experience, if needed. The model solution may contain a discussion of
common fallacies in solving the problem (essentially all corrective text
that you don't want to repeat in red ink on each of the student's
write-ups for which it applies).
The approved model solution should be have been send to me (Rob), so
that it can be posted on the web at 5pm.
- Thursday, 5pm: Team collects late homeworks from the boxes
in the Gates 4B stairway and sends me the names of the late ones.
- Thursday or Friday:
Team meets with TA to prepare uniform (consistent) partial
credit policy. Default meeting time with TA: Before discussion hours.
- Friday-Monday: Team members finish grading according to
agreed-upon partial credit policy and fill in scoresheet. The final
score for each problem should be written clearly and circled. Put your
initials next to each final score.
Fill in the scoresheet by writing the grades behind the names. Use only
tabs to separate names from grades, and do not edit the names in any way.
Unknown students may be added at the bottom.
Team returns graded homeworks (sorted alphabetically by lastname)
and the scoresheet to TA, by noon. This
is a hard deadline, as grades have to be reviewed and homeworks
returned to students in class the same day.
