Grading Policy for VO+PS "Geometric Modeling"
- According to the Austrian Universities Act 2002, students have the right
to be examined according to an alternative method if they suffer from a
permanent disability which makes it impossible for them to take an
examination in the prescribed manner and the other method does not limit
the content and standards of the examination.
Hence, if you feel that the requirements outlined below to pass VO+PS
"Geometric Modeling" cannot be met by you due to such a disability
then, please, get in touch with the University's
as soon as possible. Please understand that directives of the Rectorate
prevent me from consenting to any bilateral agreements if the
has not been involved!
This remark applies mutatis mutandis to longer illnesses. As far as
organizationally possible, I will try to come to a special arrangement with
you if you would end up being sick for an extended period of time. But, once
again, please inform me as soon as possible.
- VO "Geometric Modeling" will be graded on the basis of
oral exams that will take place in my office and that cover the material
taught in class.
- PS "Geometric Modeling" will be graded on the basis of
- Weekly individual assignments have to be worked out by each
- Unless announced explicitly otherwise, after each VO lecture (on Fridays)
I will post a sheet
with new assignments no later than on the subsequent Monday.
- All assigments (given so far) will be available as one
on the webpage of the course.
- All new assignments will be discussed in the PS class
in the week following the post date.
- Hence, in general you will have about one and a half weeks to work
out the assignments. (There might be
exceptions to this rule which I will announce clearly.)
- Please use our
"Abgabesystem" to mark those
assignments which you are willing to present in class. You can enter (or
change) your checkmarks until 01:00 on that Friday on which
the assignments are due.
- Please make sure to register for our
in time. Your "Username" is your student ID number ("Matrikelnummer"), and
you can (re)set your password via email by clicking on "Passwort
zurücksetzen: basierend auf E-Mailadresse". You will then get an
email (in English) with instructions on how to (re)set your PWD.
- Your PS grade will be based on the number of assignments for which
you declared a willingness to present them and on your performance at the
blackboard/whiteboard during the presentation of assignments.
- In addition, I will take notes of other noteworthy contributions of
students during class.
- In order to get a passing grade you are required to mark
at least MIN assignments as the ones which you are willing to present
in class, where MIN is computed as follows:
I expect X to be about(!) 48, and Y to be about 12. (For those numbers
we'd get MAX = 44 and MIN = 22.) Please note that
marking at least MIN assignments is a necessary but not a sufficient
condition for passing the PS!
- Let X be the total number of assignments posted.
- Let Y be the total number of different assignment sheets.
- Let MAX := (X/Y) * (Y-1).
- Then MIN := 0.5 * MAX.
- You can get credit for the assignments
worked out only if you attend the PS personally.
- You are not required
to hand-in your assignments, unless explicitly requested for some
- You may cooperate and discusss the assignments
with other students. (Of course, with the exception of those few
assignments for which I explicitly request everybody to come up with
his/her own solution!)
- Similarly, you are welcome to consult textbooks
or online sources.
- Frankly speaking, I do not care whether you
discuss assignments among your peers, or how you come up with a solution.
- However, I will not tolerate plagiarism: Once you mark an assignment
as solved then I expect you to fully understand your solution. That is, if
I ask you to come to the whiteboard and to explain your solution then
you'll have to be able to argue why your solution ought to be
correct, and you have to be able to answer questions concerning
(sub-)problems related to your solution.
- Please note that I
will use the quality of your explanations and arguments at the whiteboard
as a positive or negative weight when determining your final grade. In an
extreme case, this means that marking all X assignments but delivering
very poor explanations whenever I ask you to come to the whiteboard will
still result in failing the PS!
- In any case, if presented with a full
line of arguments then I will be much more lenient towards "solutions"
that fall apart. On the other hand, phrases like "It seems like..." or "I
believe that..." or "This is true!!!" (without any rational why it should
be true) simply do not belong to the line of reasoning employed by
geometric modeling, and I will react harshly to such
"solutions". Hopes and fears are an important part of everybody's life,
but geometric modeling is not about hopes or fears but about rigorous
- As a rule of thumb, if you are not convinced that you can outline a
full suite of arguments then it is likely smarter not to claim credit for
an assignment and have one assignment less to your credit, than to risk
being caught by me.
- If you'd come up with two or more solutions then
I'd advise you to focus on one solution and work it out in detail, rather
than have several "half-baked" solutions.
- For specific assignments
that are to be handed in in writing I do not allow cooperation since I do
not want to read the same solution several times, once verbatim
identically, once with "I" replaced by "J", once with "I" replaced by "K",
and so on. Part of the reason why I want you to work out written solutions
is that I would like you all to practice writing up solutions. (Clearly,
this goal is not met if one solution would be copied multiple times.)
- COVID-19 pandemic: The COVID-19 pandemic might force us
to resort to online teaching as a substitute for weekly meetings in the
- We will use a video conferencing system and meet via
https://edumeet.geant.org/held_sbg_lectures if we have to move from classroom-based teaching to online teaching.
- All video conferences will take place exactly during the
times scheduled for classroom teaching.
- The solutions for the PS
assignments will have to be presented during the video conferences in a
suitable way, e.g., by sharing one's screen.
- It is the each student's
responsibility to make sure that we will have decent means of communication
during the PS. Experience tells me that a decent communication link requires
all students to have access to a reliable and reasonably fast Internet
connection and to use a microphone plus a headset during all
- All grading regulations will stay the same and apply to
both classroom teaching and online teaching.
- Continuous-assessment mode: The PS is graded in
continuous-assessment mode, i.e., the entire
PS is part of the exam! According to applicable study law this means, in
- that attendance is compulsory throughout the entire duration of this
that a grade will be assigned even if you should decide to drop the course,
with the grading being done relative to your accomplishments achieved up to
the time when you dropped the course. This rule does not apply if you should
opt out of the course prior to the third unit of this course. Please note
that dropping the course results virtually always in the non-passing grade
that an improvement of the obtained grade is no longer possible after I
entered the grade in PLUSonline.
that the entire course must be repeated in a later semester if you should
have failed it!
