Purpose: The aim of this study is to see the possibility of application of PBL in medical education of Chungnam National University, College of medicine. Methods: The questionnaire were given to Chungnam University Medical students and professors before and after the preliminary trial of PBL. Before the trial, the questionnaire of 4 items were asked to the 199 students and the 53 professors. After the trial using 5 modules, the questionnaire of 8 items were asked to the 130 students and the 13 professors. Results: Before the preliminary trial of PBL, both the students(54%) and professors(93%) already knew the concept of PBL. The professors got the information about PBL from the Faculty in-service training, and the students got it from the professors. Professors and higher grade students wanted to apply PBL in clinical period as soon as possible. After the trial, both students and professors agreed that the trial of PBL was helpful and that the level of difficulty for modules and the role of tutor were appropriate. Students wanted to have the short period of PBL without credits during semester, but professors insisted to give the credits to students as a regular lecture. Conclusion: These results suggest that the students and professors of Chungnam Medical College, even though they have different point of view in some aspects, have the consensus for the application of PBL in regular curriculum.
