Corona-virus related changes
While we are unable to meet in person, I will post class notes on this website, on the Class Information link above. For every class there will be a short assignment that you have to complete, and email to me, as evidence that you have read the class notes. I will also try to post
videos presenting the material in the notes. You are welcome to view these instead of reading the notes.
These assignments will be each be worth 1/2 a percent of your grade. The grading scheme given below will be adjusted once we get back to normal meetings.
LMS
If you want to contact me, please do not use the LMS system. I cannot access it from my computer, so I will not look at it again. (I didn't look at it before. The department secretary helpfully set it all up for me.) Please e-mail me, phone me, or come to my office and yell under the door. Also, do not go to the LMS system for updated material. I will just have someone copy the links that are already there. Your attendence will be graded by what you send me. If it is tracked through the system, I will just ignore it.
Homework and Quizzes
There will be homework problems for each class.
You need not hand them in, but we will have a quiz about every two weeks,
chosen from the homework problems.
Many of these problems will come up on the tests.
Attendence
Quizzes will serve as a record of attendence.
Tests
There will be two tests.
We will decide the date of the exams at least 2 weeks before the exam.
Evaluation
Quizzes and Attendence: 10% Tests: 2 x 45%.
