The development of the College of DuPage's (CDP's) business mathematics course for delivery on CDP's FM radio station took place in four phases. After business mathematics was selected for radio delivery, tentative course specifications were written and discussed by a development team consisting of a mathematics instructor, a script writer from the radio-television production staff, and the Director of Instructional Design. Next, a study guide and script were prepared and reviewed by the mathematics and business faculties. The final phase was testing and validation. Course development required the preparation of various instructional materials: (1) a study guide consisting of 20 units, each to be covered during one 30-minute broadcast, and providing an overview, topic outline, unit objectives, list of key terms and concepts, reference list, unit outline, and homework exercises; (2) scripts, based on the study guide materials, in which a husband and wife study the unit together, helping each other and applying the problems to their daily lives; (3) supplementary materials; and (4) 4 tests covering the units. The course is coordinated by the CDP Learning Center which keeps student records, provides tutoring, maintains copies of the broadcasts, and serves as a testing center. A compatible development test, the use of good pedagogy and broadcast and production techniques, faculty involvement, sufficient time, adequate support staff, and a varied delivery process were keys to the development of an effective course.
