Astronomy 311
Introduction to
Astronomy
Semester I, 2005-2006
The sharp detail seen in the image at the left, captured by the
Hubble Space Telescope, is truly impressive when you consider
that this spiral galaxy (known as NGC 3370) is located about
100 million light years from us! The distance to this galaxy
was determined by observing and measuring the fluctuating
intensity of the light emanating from its Cepheid variable stars .

FINAL EXAM (Location: A-121 SCI) |
Attendance and
Grading Policies:
Attendance Policy:
|
1) It is expected that
you will attend class regularly. As you arrange your
work schedule, recreation schedule, social schedule, vacations, elective
therapies and surgeries, etc., be mindful not to create conflicts with the
schedule of lectures and exams in this course. Absences due to such activities
will not qualify as excused absences. 3) In accordance with University of Wisconsin policy, any potential conflict between class work and religious observance must be made known to the instructor within the first three weeks of classes. You must notify the instructor of the specific days or dates for which you request relief from academic requirements on account of sincerely-held religious beliefs. 4) All exams will be announced in advance. Attendance at each one is required. No student will be allowed to take an exam prior to the exam's scheduled hour. The course policies concerning missed exams are as follows:
5) If I am absent from class, in most cases another instructor will either substitute for me or will announce that the class session has been canceled. If there is no substitute instructor, nor any announcement, please remain in the classroom for ten minutes before departing. |
Grading Policy:
|
1) Your numerical
course grade will be based on the following:
25% Exam 1 2) Exams will cover material from lectures and assignments, including assigned readings. 3) Your letter grade
for the course will be determined by your numerical course grade (see item
1 above). The borderline
between an A- and a B+ will be no higher than a numerical course grade of
90. The borderlines between
B-/C+, C-/D+, and D/F will be no higher than numerical course grades of
80, 65, and 50, respectively. |
