In course design, instructors are charged with enacting the curriculum and its plans. Course design requires the instructor to develop materials to teach the given content. The interface between curriculum and instructional design provides a context to examine key factors to effective design. This is particularly true in a course designed with a learner-centered focus. Thus Curriculum and instructional design (CID) should be understood as a continuum of design. Finally, this leads to plans for a more effective and coherent course for students.
