COVID-19 health and safety requirements
Students are responsible for
abiding by the university’s COVID-19
health and safety expectations. All students attending this class in-person
are required to follow university policy
regarding health, safety, and face coverings:
•
• wear a face covering in all
university classrooms, laboratories, studios, and other in-person instructional
settings and learning spaces. Face coverings are additionally required to be
worn indoors in all university buildings, and outdoors when other people are or
may be present where physical distancing of at least 6 feet from others is not
possible. Students with a documented health or medical condition that prevents
them from wearing a cloth face covering should consult with Student Accessibility Services in the
Dean of Students Office.
•
• ensure that the face covering
completely covers the nose and mouth and fits snugly against the side of the
face.
•
• practice physical distancing to
the extent possible.
•
• assist in maintaining a clean and
sanitary environment.
•
• not
attend class if you are sick or experiencing symptoms of COVID-19.
•
• not
attend class if you have been told to self-isolate or quarantine by a health
official.
•
• follow the instructor’s guidance
with respect to these requirements. Failure to comply constitutes disruptive
classroom conduct. Faculty and teaching assistants have the authority to deny a
non-compliant student entry into a classroom, laboratory, studio, conference
room, office, or other learning space.
These requirements extend outside
of scheduled class time, including coursework in laboratories, studios, and
other learning spaces, and to field trips. These requirements may be revised by
the university at any time during the semester.
In accordance with university
policy, instructors may use a face shield while they are teaching as long as
they are able to maintain 8 feet of physical distance between themselves and
students during the entire instructional period. Some form of face covering
must be worn at all times in learning spaces regardless of the amount of
physical distancing.
Faculty may refer matters of
non-compliance to the Dean of Students Office for disciplinary action, which
can include restrictions on access to, or use of, university facilities;
removal from university housing; required transition to remote-only
instruction; involuntary disenrollment from one or more in-person courses; and
other such measures as necessary to promote the health and safety of campus.
It is important for students to recognize
their responsibility in promoting the health and safety of the Iowa State
University community, through actions both on- and off-campus. The university’s
faculty asks that you personally demonstrate a commitment to our Cyclones
Care campaign.
Iowa State University’s faculty support the Cyclones Care campaign and ask you
personally to demonstrate a commitment to our campaign. Your dedication and
contribution to the campaign will also protect your family, classmates, and
friends, as well as their friends and families. Our best opportunity for a successful
fall semester with in-person learning and extramural activities requires all of
us to collaborate and fully participate in the Cyclones Care campaign.
Policy for Addressing
Disruptive Conduct in the Learning Environment
For student
learning to be most effective, learning environments must remain civil, safe,
collaborative, and free from conduct that unreasonably disrupts, impedes,
obstructs, or interferes with the educational process. The university
recognizes the importance of open inquiry, freedom of expression, and viewpoint
diversity within its Learning Environments, and all members of the
university—including faculty, staff, students, and administrators—should feel
free to express their viewpoints without fear of reprisal (FH 7.1); however, students have an obligation to engage in the educational
process in a civil manner that does not unreasonably disrupt the educational
experiences of their fellow students or the instructor’s course objectives.
Conduct
that unreasonably disrupts the ability of instructors to teach or students to
learn can be prohibited as disruptions of university activities in violation of
this policy. Instructors have the right and responsibility to ensure that a
safe and functional learning environment is maintained. Importantly,
instructors have the authority and discretion to address disruptive conduct.
Students who engage in disruptive conduct may be subject to disciplinary
action, including possible removal from a course(s) and/or referral for sanctioning
under the Student Disciplinary Regulations.

Prep Week
This class follows
the Iowa State University Prep Week policy as noted in section 10.6.4 of the Faculty
Handbook.
Teamwork, collaboration, and helping each
other:
For tasks intended
for group work, you are expected to find a partner and share the tasks among
the group members. In a group project, effective teamwork is critical to
maximize the productivity of the whole group. In the submitted work, identify
components and indicate percentage contribution by each member to each
component.
For tasks not
intended for group work, individual submission is required. In this case, you
are encouraged to discuss among your friends on how to attack problems.
However, you should write your own solution. Copying other people’s work is
strictly prohibited.
Academic dishonesty:
The class will follow Iowa State University’s
policy on academic dishonesty. Anyone suspected of academic dishonesty
will be reported to the Dean of Students
Office.
Cheating is a very
serious offense. It will be dealt with in the most severe manner allowable
under University regulations. If caught cheating, you can expect a failing
grade and initiation of a cheating case in the University system.
If in doubt about
what might constitute cheating, send an e-mail to your instructor describing
the situation. If you notice anyone cheating, please report it to the
instructor or the TA. Do not deal with it yourself.
Discrimination and
Harassment:
Iowa State
University does not discriminate on the basis of race, color, age, ethnicity,
religion, national origin, pregnancy, sexual orientation, gender identity,
genetic information, sex, marital status, disability, or status as a U.S.
Veteran. Inquiries regarding non-discrimination policies may be directed to Office
of Equal Opportunity, 3410 Beardshear Hall, 515
Morrill Road, Ames, Iowa 50011, Tel. 515-294-7612,
Hotline 515-294-1222, email eooffice@iastate.edu
Let us make every effort
to work together and create a positive, collegial, caring, and all-supportive
learning environment in our classroom, laboratory, TA office, and instructor
office.
Accessibility Statement:
Iowa State University is committed to assuring that all educational
activities are free from discrimination and harassment based on disability
status. Students requesting accommodations for a documented disability are
required to work directly with staff in Student Accessibility Services (SAS) to
establish eligibility and learn about related processes before accommodations
will be identified. After eligibility is established, SAS staff will create and
issue a Notification Letter for each course listing approved reasonable
accommodations. This document will be made available to the student and
instructor either electronically or in hard-copy every semester. Students and
instructors are encouraged to review contents of the Notification Letters as
early in the semester as possible to identify a specific, timely plan to deliver/receive
the indicated accommodations. Reasonable accommodations are not retroactive in
nature and are not intended to be an unfair advantage. Additional information
or assistance is available online at www.sas.dso.iastate.edu,
by contacting SAS staff by email at accessibility@iastate.edu,
or by calling 515-294-7220. Student Accessibility Services is a unit in the
Dean of Students Office located at 1076 Student Services Building.
Religious Accommodation:
Iowa State University welcomes diversity of religious beliefs and practices, recognizing the contributions differing experiences and viewpoints can bring to the community. There may be times when an academic requirement conflicts with religious observances and practices. If that happens, students may request the reasonable accommodation for religious practices. In all cases, you must put your request in writing. The instructor will review the situation in an effort to provide a reasonable accommodation when possible to do so without fundamentally altering a course. For students, you should first discuss the conflict and your requested accommodation with your professor at the earliest possible time. You or your instructor may also seek assistance from the Dean of Students Office at 515-294-1020 or the Office of Equal Opportunity at 515-294-7612.

About mutual respect and professionalism:
You are expected to treat your instructor and all other participants in the course with courtesy and respect. Your comments to others should be factual, constructive, and free from harassing statements. You are encouraged to disagree with other students, but such disagreements need to be based upon facts and documentation (rather than prejudices and personalities). It is the instructor’s goal to promote an atmosphere of mutual respect in the classroom. Please contact the instructor if you have suggestions for improving the classroom environment. It is preferable if students discuss issues directly with the instructor, however, students may also leave a note in the instructor’s mailbox.
Relevant to the ISU Inclusive Language policy:
All university publications and communication, whether oral or written, shall use inclusive language and illustrations. Inclusive language refers to language that makes every attempt to include comprehensively all groups in the community. Whenever possible, selection of academic materials will also reflect efforts to uphold this university policy.” Visit the Policy Library’s Inclusive Language website (http://www.policy.iastate.edu/policy/language).
Related to usability, disability and design:
I am committed to creating a course that is inclusive in its design. If you encounter barriers, please let me know immediately so that we can determine if there is a design adjustment that can be made or if an accommodation might be needed to overcome the limitations of the design. I am always happy to consider creative solutions as long as they do not compromise the intent of the assessment or learning activity. You are also welcome to contact the Student Accessibility Services (515-294-7220) to begin this conversation or to establish accommodations for this or other courses. I welcome feedback that will assist me in improving the usability and experience for all students.
