Three Kinds of Problem-Based Learning Formulas Experienced in Konkuk University College of Medicine / 한국의학교육

We performed three kinds of problem-based learning (PBL) formulas in all of forty-one 3rd grade students after the final examination of the first semester from June 28, 1999 to July 9, 1999 at Konkuk University College of Medicine to investigate which formula is the most efficient and helpful in medical education and polyclinic course. The PBL formulas applied were the typical face-to-face PBL accompanied by mini-lecture (Type I) or by distribution of the guidelines without lecture (Type II) and cyber PBL using web-based module and discussion over cyber space (Type III). Response of students was surveyed using some questionnaires and the evaluation results of each PBL were analyzed with Pearson's correlation test. All participating students were satisfied with the face-to-face PBL especially in applying time of PBL, using discussion to solve the problem, and studying with tutors. In cyber PBL, in spite of excellency of the contents, limitations in discussion over cyber space and computer skills, misunderstanding of computer system, and additional cost for private PC rent seemed to decrease the satisfaction with this PBL. Experience in Type II PBL was turned out to be the most helpful and discussion among fellow students in PBL to be the most useful experience for incoming polyclinic course. There were no significant correlations between the evaluation results of face-to-face PBL and cyber PBL or between the evaluation results of each type of PBL and the average credit of that semester, suggesting that evaluation of the newly acquired knowledge through PBL using tools such as Triple Jump, OSCE (objective structured clinical examination), and MEQ (modified essay question) should be included in assesment of academic achievement in addition to the evaluation of activities during PBL.

An Experimental Trial of Web-based Problem Based Learning / 한국의학교육

In this paper, we present some results from an experimental web-based Problem-Based Learning(PBL) course, which was offered to 64 medical students in the first grade at Konkuk university for 7 weeks. For the course, we developed a web-based PBL module, which is composed of three sections. The first section includes the 8 stages of problem probing and solving in patient's care. In every stage, the students can browse all the data for the problem solving. The second section contains some problems for evaluating the academic achievement of the students who successfully passed in the first section. In the third section, some questionnaires are presented to survey the students response. The followings are the results. 1. Average score of the first section was 64.1+/-13.2. Most students participated in the course with integrity, and especially seven students(11%) were remarkable in their clinical reasoning. 2.The student's computer skill did not largely affect their academic achievements. However, it is desirable for the students to learn basic computer usage in advance. 3.A few students attended to the discussion through bulletin board facilities. Considering the importance of discussion in PBL, we need to devise a new way of attracting students in the discussion. 4. The survey showed that sixty five percent of the students thought that the lecture was effective and ninety one percent of them that it would be better if it is offered as a regular course during summer or winter vacations. Seventy five percent of students became to realize the importance of basic sciences such as biochemistry and physiology after this course. 5. There were many students who complained about the malfunctioning of the system. The system should be modified to be more reliable and robust. In conclusion, the web-based PBL course provided an effective way of learning in medical education. It also turned out to be used as an alternative of traditional PBL and especially useful for self study.
