Model Courses/ Linear Algebra

Introduction

This PREP Linear Algebra model course is a work in progress. Some of the problem sets below will likely be adjusted over the next several months (Winter/Spring 2012). Future updates will be indicated by the date when the changes are made.

A first-term Linear Algebra course could be taught in many different ways. A course in Linear Algebra could have more emphasis on applications than theory or vise-versa. The course could be taught on the quarter system or the semester system (or other time frame). Because of these and other variables, it is likely that an instructor who uses this model course will need to adjust some problem sets.

It is expected that an instructor will first import some or all of these problem sets into their WebWork course. Once the course is created and these problem sets are imported, there are a couple of options for how to use the problem sets. One way to use these sets is to make new problem sets and use the option in the WW library browser that allows one to search for problems from within the course (the local course created by the instructor). Essentially this method gives a refinement of the NPL, making it easier to find problems. Another option would be to use these problems sets and edit the sets as needed.
