Rutgers has been very supportive of innovations like this one. There are many positive aspects of linked courses. Instructors from various disciplines interact and learn a great deal from each other. Biology teachers learn about writing and English teachers learn biology, Students interact as a community with each other and the instructors. This often results in study groups etc. which enhances learning and improves grades.
Linked courses are a great opportunity to discuss controversial and differing views in class.
Students learn about the issues, discuss them and write about them. By doing revisions for the English instructor students improve the content and writing skills. When instructors take the lead and establish linkages, institutions tend to develop ways of supporting these innovations. Only teachers who are committed and willing to experiment tend to agree to teach linked courses. Our experience has been very good.
