Solutions and explanations should be clear enough so that one of your peers could easily follow what you did if they had not worked the problem before. When
a quiz, exam, in-class or take-home exercise calls for a calculated
answer, no matter how simple, you increase your chances of arriving at the correct answer (and receiving partial credit) if you show a clear, step-by-step solution using dimensional analysis (unit conversions). This means that you need to show
the units (dimensions) on each number and the conversion factor or
equation used in each calculation.
Originality. All work must be original and
your own. Penalties, such as automatic grades of zero, will result from cheating, copying, plagiarism, or deceit
of any kind (SDCCD
Policy 3100.3). Plagiarism on an in-class quiz or exam includes use of
pre-written
hints or notes, looking at another student's paper, allowing (or not
preventing) another student to copy your answers, or use of a programmable
calculator (see page 1).
Collaboration. I expect and encourage collaboration among you and your peers while working on in-class and take-hom activities, but not on quizzes or exams. In any case, the work you submit to
me must
be your own, not a copy from another student. The guideline
is that you should have no trouble explaining or repeating work that you turn in.
Plagiarism. If you look at someone else's paper during an exam or quiz, or copy directly from another student on any assignment, then you and the person
from whom you copied will both earn a zero on the assignment without notice or exception. Mesa
College may
also wish to pursue academic sanctions, expulsion, and/or legal proceedings. Please be fair.
Make-Up Work. Make-ups are not available for exams, quizzes, and in-class activities, whether
your absence is excused or not. Your lowest exam score is dropped if your quiz average is higher.
Take-home activities must be turned in at the beginning of class on the due date. If you will be absent the day that a take-home assignment is due, you may submit your work on time via scan/email, fax, or by dropping it off at my faculty mailbox. You may submit late take-home activities after the due date/time, with grade reduction of 50% per class day starting at the time it is due (i.e., 2:20 pm on the due date). |
