Changes in education and technology have influenced medical education and have altered many traditional concepts of teaching & learning skills. We are familiar with the traditional lecture in the classroom, but there are a lot of limitations to this method. In order to overcome geographical and time constraints of the limitations, I have tried implementing a cyber class using the internet lectures, homework, discussions, and even examination for the graduate medical course. The purpose of this study was to find alternatives for improvement of teaching and learning methods in medical education, especially in graduate courses. The cyber class was conducted on the internet with 69 medical graduate students in a course on the pre- & postoperative management of the surgical patient. Each student used his/her personal computer, and he/she entered the cyber classroom of the server computer of Chungnam National University (http://cyber.chungnam.ac.kr), connected to the auther's homepage. The computer program consisted of several menus and the system was also able to automatically check the student's contact number and duration, submission of homework, examination and discussion. I believe that the cyber class using internet is a useful tool for graduate medical course.
