The purpose of this study was to identify an appropriate integrated instructional design model for Continuing Medical Education using electronic learning method and compare it with traditional method. In this quasi-experimental study 60 General physicians and assistants according to the recall of Kermanshah University of Medical Sciences in Iran and by available sampling method in two 30- staff groups were participated.
