Two or more courses, each with its own instructor, are scheduled to meet at the same time and paired to the extent that they meet jointly with both instructors at intervals throughout the semester and/or share some assignments or projects.
Another way to implement this model is to package a set of two or three courses in different disciplines that are linked by common theme for offering in different time slots in a single semester to a single student cohort. In this example, the instructors of the connected courses team up to attract a common set of students, coordinate with each other to create sufficient coherence across the different courses, and provide some common integrating experiences to highlight the cross-disciplinary connections, similarities and differences. It is possible to create project assignments that would allow students to link what they are learning in the different courses.
