- Text and Syllabus: "Elementary Number Theory" by James K.
Strayer. We will cover Chapters 1-4 essentially in full, and
selected topics from the remainder of the text, depending on the time
available and student interest.
Your course grade will be based on the accumulated number of points
earned from the following components: (1) the Final Exam, (2) three
midterm exams, and (3) homework assignments.
The total number of points to be earned is 500 points, broken
down as follows:
- FINAL EXAM: 150 points. The Final Exam will be given at the
official final exam time slot for this class, Friday, May 6, 2022, 8
am - 11 am, Room TBA.
- MIDTERM EXAMS: 250 points. Three in-class midterms, each
worth 100 points. The lowest midterm score will count only 50%;
that is, the lowest half of a midterm will be dropped. Put
differently, the 50% drop-score policy means that the points penalty
from your worst midterm is cut in half; for example, if
your lowest midterm score is 70/100, instead of losing 30 points from
this midterm, you will only lose 15 points.
- HOMEWORK: 100 points. There will be 11 weekly homework
assignments, each worth 10 points, with the lowest score
assignments will be due during the first two weeks of class; the first
assignment will be given out by January 24, and will be due January
Letter grade assignments: Letter grades will be based on the
total number of points earned at the end of the semester, using the
standard 90/80/70/60 scale (96.6% = A+, 93.3% = A, 90% = A-, etc.), with
possibly some adjustments downward (resulting in a more generous
curve) depending on the overall score distribution in the class. For
example, if you end up with 450 out of 500 points (i.e., 90%), you are
guaranteed at least an A-; 400 points will
guarantee at least a B-; and so on. The actual cutoffs
may end up being more generous, i.e., more favorable to you!
- Group work policy: Group work on the homework is fine and
indeed encouraged, with the following restrictions:
- You are free to discuss problems with other students and exchange
ideas, but you must
write up the solution yourself, in your own words.
Blindly copying another student's work would defy the purpose of the
homework assignments and would backfire in exams where each student is
on his/her own.
Collaboration on extra credit
problems is not allowed.
- Missed exams/homework: If you miss an exam or homework and
have a valid excuse, I will mark the exam/homework as "excused"; in
that case, your score for the exam or homework you missed will be the
average of the scores on your other exams or homeworks. Valid excuses
include illness, an out-of-town job interview, etc., and must be
appropriately documented, e.g., by an
absence letter issued by the Office of the Dean of Students, 300
Turner Student Services Building, 610 East John Street. For more
information click on the above link.
- Attendance. This is an in-person class (except for the first
week), and attendance is expected. If you feel ill, or if you
are in Covid isolation/quarantine, please do not come to class. Contact
me (firstname.lastname@example.org) as soon as possible to discuss alternative
arrangements (e.g., turning in homework by email); I would be happy to
set up a Zoom meeting with you to go over any material you missed.
- Accommodations. To obtain disability-related academic
adjustments and/or auxiliary aids, students with disabilities must
contact the course instructor and the Disability Resources and
Educational Services (DRES) as soon as possible. To contact DRES, you
may visit 1207 S. Oak St., Champaign, call 333-1970, e-mail
email@example.com or go to the DRES website. If you
require DRES accommodation (such as extended time) for exams, please
email your accommodation letter to me (firstname.lastname@example.org) at least one
week before the first exam.
- Covid-19 Policies. Please observe the University's Covid-19
Policies. In particular, to attend the in-person class meetings,
students must have "Building Access Granted" status and wear face
