Model Courses/ Linear Algebra


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.

One could first import these problem sets into their WebWork course and then use them as a resource for building new problem sets. To do this, simply use the option in the WW library browser that allows one to search for problems within the course. This could be an easier method then to edit the problem sets themselves.
