Some, but not all of the problems will be graded. Justify all your answers.
You should assume that late work will not be graded.
- Students With Disabilities
- If you qualify for accommodations because of a disability, please
submit your accommodation letter from Disability Services to your faculty
member in a timely manner so that your needs can be addressed. Disability
Services determines accommodations based on documented disabilities in the
academic environment. Information on requesting accommodations is located
on the Disability Services website. Contact Disability Services at
303-492-8671 or dsinfo@colorado.edu for further assistance. If you have
a temporary medical condition, see Temporary Medical Conditions on the
Disability Services website.
- Missed Exams
- If you know that you are going to miss an exam or cannot take the final
exam at the scheduled time, please notify your instructor at least two weeks
in advance. If you miss a midterm exam for any acceptable reason (e.g.
religious obligation, illness), that midterm exam score will be
replaced by an estimated score based on your performance on the other midterm.
If you miss both exams for acceptable reasons, your midterm scores will be
replaced by estimated scores based on your performance on the final.
If you miss the final exam and have not rescheduled it in
advance, you will score zero on the final or receive an incomplete in the
course, depending on the circumstances. You may not reschedule a final after
the final has started.
- Classroom Behavior
- Both students and faculty are responsible for maintaining an appropriate
learning environment in all instructional settings, whether in person, remote
or online. Those who fail to adhere to such behavioral standards may be
subject to discipline. Professional courtesy and sensitivity are especially
important with respect to individuals and topics dealing with race, color,
national origin, sex, pregnancy, age, disability, creed, religion, sexual
orientation, gender identity, gender expression, veteran status, political
affiliation or political philosophy. For more information, see the classroom
behavior policy, the Student Code of Conduct, and the Office of Institutional
Equity and Compliance.
- Please, no open yawning or sleeping in class!
- CU Boulder recognizes that students' legal information doesn't always
align with how they identify. Students may update their preferred names and
pronouns via the student portal; those preferred names and pronouns are
listed on instructors' class rosters. In the absence of such updates, the
name that appears on the class roster is the student's legal name.
- Requirements for COVID-19
- As a matter of public health and safety, all members of the CU Boulder
community and all visitors to campus must follow university, department
and building requirements and all public health orders in place to reduce
the risk of spreading infectious disease. CU Boulder currently requires
COVID-19 vaccination and boosters for all faculty, staff and students.
Students, faculty and staff must upload proof of vaccination and boosters
or file for an exemption based on medical, ethical or moral grounds
through the MyCUHealth portal.
- The CU Boulder campus is currently mask-optional. However, if public health
conditions change and masks are again required in classrooms, students who
fail to adhere to masking requirements will be asked to leave class, and
students who do not leave class when asked or who refuse to comply with
these requirements will be referred to Student Conduct and Conflict
Resolution. For more information, see the policy on classroom behavior
and the Student Code of Conduct. If you require accommodation because a
disability prevents you from fulfilling these safety measures, please
follow the steps in the "Accommodation for Disabilities" statement on
this syllabus.
- If you feel ill and think you might have COVID-19, if you have tested
positive for COVID-19, or if you are unvaccinated or partially vaccinated
and have been in close contact with someone who has COVID-19, you should
stay home and follow the further guidance of the Public Health Office
(contacttracing@colorado.edu). If you are fully vaccinated and have been
in close contact with someone who has COVID-19, you do not need to stay
home; rather, you should self-monitor for symptoms and follow the further
guidance of the Public Health Office (contacttracing@colorado.edu).
- Honor Code
- All students enrolled in a University of Colorado Boulder course are
responsible for knowing and adhering to the Honor Code. Violations of the
Honor Code may include, but are not limited to: plagiarism, cheating,
fabrication, lying, bribery, threat, unauthorized access to academic
materials, clicker fraud, submitting the same or similar work in more than
one course without permission from all course instructors involved, and
aiding academic dishonesty. Any incident of academic misconduct may be
reported to Student Conduct & Conflict Resolution (honor@colorado.edu);
303-492-5550). Students found responsible for violating the Honor Code
will be assigned resolution outcomes from the Student Conduct & Conflict
Resolution as well as be subject to academic sanctions from the faculty
member. Additional information regarding the Honor Code academic integrity
policy can be found on the Honor Code website.
- Sexual Misconduct, Discrimination, Harassment and/or Related Retaliation
- CU Boulder is committed to fostering an inclusive and welcoming learning,
working, and living environment. University policy prohibits sexual
misconduct (harassment, exploitation, and assault), intimate partner
violence (dating or domestic violence), stalking, protected-class
discrimination and harassment, and related retaliation by or against members
of our community on- and off-campus. These behaviors harm individuals and
our community. The Office of Institutional Equity and Compliance (OIEC)
addresses these policies, and individuals who believe they have been
subjected to misconduct can contact OIEC at 303-492-2127 or email
cureport@colorado.edu. Information about university policies, reporting
options, and support resources can be found on the OIEC website.
- Please know that faculty and graduate instructors have a responsibility
to inform OIEC when they are made aware of any issues related to these
policies regardless of when or where they occurred to ensure that
individuals impacted receive information about their rights, support
resources, and resolution options. To learn more about reporting and
support options for a variety of concerns, visit
Don't Ignore It.
- Religious Holidays
- Campus policy regarding religious observances requires that faculty
make every effort to deal reasonably and fairly with all students who,
because of religious obligations, have conflicts with scheduled exams,
assignments or required attendance.
- In this class, you should inform your professor of any
conflict as soon as possible.
In the case of conflicts with exams, if you do not inform your instructor
of the conflict at least two classes in advance of the exam,
you must provide documentary evidence of the religious obligation.
- See the campus policy regarding religious observances for full details.
