Joseph Steinmetz, dean of the College of Liberal Arts and Sciences at KU, citing concerns over the rising cost of a college education and the needs to the student body, said that differential tuition on classes in the college is dead – for now.Differential tuition is an extra fee, which is retained by the school or college where the course is taught, tacked onto certain classes. CLAS and the School of Social Welfare are the only academic divisions that don’t charge differential tuition.”I looked at the numbers a lot over the past year, and I’ve determined for now that it’s just not worth it,” Steinmetz said. “I know how expensive an education is. I have a son at Indiana.”In a wide-ranging interview with the Journal-World on Tuesday, Steinmetz said that he hoped to update the majors and classes offered in the college to bring them more in line with what is going on in the world.”Most of the major innovations in the academy are going on at the intersection of many different departments,” he said.Steinmetz said that as part of his comprehensive plan, he would encourage more classes to be co-taught to include experts from different departments and to better cover areas that might have an impact not only on economics, for example, but also on sociology and psychology.Steinmetz also said that he hoped to revitalize graduate programs, increase course offerings and help students graduate in four years by adjusting the general education requirements.
