Abstract
To motivate students in classes by establishment of interactive communication between the students and a teacher, we provided construction-type slides to the students before lectures through a e-learning system and randomly assigned students questions to fill the construction-type slides in the lectures. From comparison between the same classes in two years which were performed with and without this educational method, score in examination was found to be slightly high in the class with this method. In addition, lecture evaluation questionnaires to the students revealed that this method surely motivated students and stimulated participation in the lecture.
