CSU Fullerton: professor reprimanded for choosing less expensive textbook

A CSU Fullerton associate professor has been reprimanded for failing to assign the "common textbook" chosen by the department for Intro to Linear Algebra and Differential Equations. 

Instead of a $180.00 tome written by the Math Department chair and vice-chair, the professor assigned a $75.00 text and additional open-source, OER materials (online educational resources). 

An appeal of this action is being heard today.
