NOTE: All homework problems must be accessed though the course website.
RWU Policy on Disability Accommodations:
Students who wish to receive academic accommodations for this course must first register with Student Accessibility Services (SAS) in order to begin the accommodation process. The SAS office will provide registered students with the specific information they will need to share with each instructor. SAS is located on the second floor of the Main University Library and is open from 8:00 am to 5:00 pm Monday through Friday.Website:
Homework Format:
Homework solutions must conform to posted solution standards
Class Surveys:
Students are requested to complete anonymous class surveys and/or quizzes by 10:00PM on the day of class through the Bridges system. Surveys are never right or wrong, but thoughtful completion is required for credit. Thoughtful and non-plagiarized survey responses are worth one point each.
Assistance/Collaboration Policy:
Students have the option of forming homework groups or may complete the assignments individually. Group homework assignments acknowledge the benefit of forming small study groups to complete challenging assignments. However, groups will not be required to carry members that do not equally contribute. At any time during the semester a simple majority of members may declare a group member to be non-contributing. This declaration will not affect assignments already submitted, but the group will be divided and separate homework problems assigned for the remainder of the semester. Each student is expected to have contributed to, and have intimate knowledge of the problems submitted on their behalf.
Formal Attendance and Lateness Policy:
Regular attendance in classes is expected of all students. Faculty members are in no position to assess the validity of excuses and the Student Health Service will not provide notes or vouch for student health.Absences equivalent to one week of class are allowed to all students for any and all reasons.No explanation is necessary for these absences. Absences above this number affect the final course grade according to the following schedule.
Absences equivalent to one week / No effect on final grade1 more absence / Final grade lowered by ½ letter grade.
2 more absences / Final grade lowered by 1 letter grade.
3 or more absences / Final grade of F assigned (Official withdrawal recommended).
Attendance is typically monitored using "sign-in sheets" for each class meeting.It is the responsibility of the student to sign-in during each class attended.A student is considered absent of his or her signature does not appear on the sign-in sheet. Forgery of signatures on sign-in sheets is a violation of university Academic Integrity Policies and subject to disciplinary action.
Tardiness: Each three instances of excessive tardiness (e.g. > 5 minutes) will count as one absence.
Late assignments: Due to the group assignment structure, only one late assignment will be accepted during the semester, no more than two weeks late. Final deadline for all homework is 24 hours before the final exam.
