A Spiral-Sequenced Guided Design Course in Electronic Communication Systems

An introductory communications systems course was designed and implemented as a fivefold, iterated guided design learning experience with the introduction of new technical material in each module. The overall plan approximated the Land transformation theory model by having a gradual increase in both content and problem solving process learning during the 15-week semester. The modules featured a satellite downlink system, time and frequency domain concepts and filter circuits, frequency conversion (heterodyne), and pulse code modulation theory. Two questionnaires were used to evaluate, anonymously, the students' responses to the guided design strategy. While recognizing the attributes of this method of instruction, the students expressed ambivalence for the guided design and lecture methods of learning. The course was implemented successfully.
