The problem with textbooks is that they offer little accommodation to professors who disagree over how and in what order material should be taught, says M. Ryan Haley, an associate professor of economics at the University of Wisconsin at Oshkoshâ??s College of Business. On the other hand, Haley says, professorsâ?? ability to cut and paste electronic textbooks according to their own preferences can result in uneven development of students across a single program and foil the expectations of those teaching advanced courses.
