When you send me email, please begin the Subject field with “ECS 235A” so I see that the letter has to do with the class. I receive lots of email and, while I look at it all, I sometimes fall behind. When that happens, I skim the Subject fields to see which letters are very important. Putting “ECS 235A” at the beginning of the Subject field will tell me it is very important.

Class Web Site
To access the class web site, go to Canvas (http://canvas.ucdavis.edu) and log in using your campus login and password. Then go to ECS 235A in your schedule. I will post announcements, assignments, handouts, and grades there, and you must submit assignments there. The alternate web site,
has everything except the Zoom information, your grades, and you cannot submit work there.
There will be both homework and a project, which tentatively will each be weighted 50%. I reserve the right to change this. There will be no final examination.
UC Davis Student Resources
UC Davis has developed a web site of student resources.
The resources cover academic support, health and wellness, career and internships, and the campus community.
The web site is https://ebeler.faculty.ucdavis.edu/resources/faq-student-resources/.
Please consult it whenever you feel necessary.
And as always, feel free to reach out to me, too.
If I can’t help, I will suggest people and places that might be able to.
The UC Davis Code of Academic Conduct,
available at https://sja.ucdavis.edu/files/cac.pdf, applies to this class.
For this course, all submitted work must be your own. You may discuss your assignments with classmates or the instructor to get ideas or a critique of your ideas, but the ideas and words you submit must be your own. Unless explicitly stated otherwise, collaboration is considered cheating.
Remember to cite, and give the source for, anything you copy or paraphrase, as is standard academic protocol. Plagiarism is cheating and will be handled as such.
Any cheating will be reported to the Student Judicial Agency (the SJA).
