CANVAS:   All class materials (syllabus, calendar, homework assignments, lecture notes, and supplements), announcements and grades will be distributed using the Virginia Tech Learning Management System, CANVAS http://www.canvas.vt.edu/

Grading:

Homework    35%     Typically, one per week, except during exam weeks and breaks.
Exam 1         20%      10:10-11:00, February 28, Randolph 331
Exam 2         20%      10:10-11:00, April 11, Randolph 331
Final Exam    25%      1:05-3:05pm, May 04, Randolph 331

Grading will be according to the default grading scale in Canvas (with +/- grades)

Homework:

1. Homework will typically be assigned on Monday and be due on Sunday at 11:59pm.
2. Homework turned in late will receive partial credit according to the following rules:

• 25% off if turned in after 11:59pm on due date, but before Monday at 11:59pm
• 50% off if turned in after Monday at 11:59pm.
• No credit if turned in after one week
• Exceptions will be made under extreme circumstances.
• Solutions will be made available within a week after the due date.
• Homework must be submitted as a PDF on Canvas.

Exams:  All tests and exams will be open notes and open book and will be administered in class electronically via Canvas, thus a device (tablet, laptop, etc.) with web access is required. Canvas supports the last two versions of every major browser release.  Contact Dr. Paterson if this will pose a problem.  Any questions about the grading of your tests/exams will need to be submitted to Dr. Paterson within one week of receiving your grade.

Grade Disputes: If a student feels that an exam or homework set was graded unfairly, or if there is an error in the grading, it should be brought to the attention of Professor Paterson within one week after the graded material is handed back. Scores will not be reconsidered beyond one week after they are handed back.

Attendance and Use of Electronic Devices: Students are expected to attend all classes.  While you are in class, please be courteous of your classmates by not engaging in activities that could be a distraction. If you are using a tablet or laptop during class, you have two options: only have your notes open (preferably with the screen laying flat on the desk in front of you) or sit in the back of the class. All other electronics should be silenced/turned off and put away before class begins.

Honor Code:  The Undergraduate Honor Code pledge that each member of the university community agrees to abide by states:  “As a Hokie, I will conduct myself with honor and integrity at all times. I will not lie, cheat, or steal, nor will I accept the actions of those who do.”  Students enrolled in this course are responsible for abiding by the Honor Code. A student who has doubts about how the Honor Code applies to any assignment is responsible for obtaining specific guidance from the course instructor before submitting the assignment for evaluation. Ignorance of the rules does not exclude any member of the University community from the requirements and expectations of the Honor Code. For additional information about the Honor Code, please visit: http://www.honorsystem.vt.edu/.

Disabilities:  Students are encouraged to address any special needs or special accommodations with me during the first two weeks of the semester, or as soon as you become aware of your needs. Those seeking accommodations based on disabilities should obtain a Faculty Letter from the Services for Students with Disabilities office (540 231 0858) located at 310 Lavery Hall (above Turner Place Dining Center).
