schwit1 writes: California State University at Fullerton brought a grievance against associate professor Alain Bourget recently. It wasn't for poor results or questionable conduct — it happened because Bourget refused to assign a $180 textbook for his introductory linear algebra and differential equations course, instead using one that cost $75 and supplementing it with free online materials. "Bourget maintains that his choices are just as effective educationally and much less expensive, so he should have the right to use them. But the university says that it makes sense for courses that have multiple sections to all use the same textbooks. Both Bourget and the university say their positions are based on principles of academic freedom."
