Open educational resources (OER)

The following free or inexpensive materials are used for this course:


This course is taught remotely: at a minimum you will need a device and internet connection that lets you see and hear a Zoom meeting.
A microphone / camera is suggested, but not required - you can type any questions into Zoom chat. Additionally, your device will need to allow you to read pdfs, access our interactive course D2L page, and send documents back to me.

Access to a printer will let you print the projects and exams to work on printed copies (and then scan them back), as well as any class notes and activities I might post. A printer is not required, though.

Instructor comments:

Hi everyone! PCC is still remote for Spring term, so we’ll have class over Zoom. Twice a week we’ll get together at 9:00am online for a couple of hours or so, with a break at the midpoint. I’ll answer questions, present material, and give time to work on the material (either in groups or on your own). We will have weekly submitted homework (like the lab write-ups from 251 and 252, but fewer questions), and weekly quizzes through D2L. There's also homework from the book, because the only way to learn math is by doing math. The Zoom meetings will all be recorded, but coming to class is crucial for understanding and success.

I love this material, and I love teaching it – vectors are a foundational concept, and one of the primary ways we model the world. Infinite series and sequences are the first time we significantly engage with infinity and infinite concepts; thinking about infinity is what started me down the math that led me to being a math teacher.

Remote instruction takes more time and requires more organization to succeed; here is a series of videos made by PCC math instructors with some advice for success in a remotely-taught class:
