The oral board examination for plastic surgery: seeking a better way.

Passing written and oral certifying examinations is a prerequisite to obtaining the license required from the Ministry of Health to start practicing as a Plastic Surgeon in Israel. In recent years, residents have complained about the unfairness of the method of the oral examination in terms of questions that varied according to the examiner. Before instituting changes, the position and attitudes of plastic surgeons in Israel, both senior surgeons and residents, regarding the oral examination was investigated. A detailed questionnaire containing 20 questions was distributed among 44 senior surgeons and 17 residents who attended the Annual Meeting of Israeli Plastic and Reconstructive Surgery Association in November 2001. The answers were analysed using the Pearson chi square test. According to this survey, a majority of responders agreed that the format of the oral examination should be changed. Although significant differences were found among the senior surgeons and the residents, the approach of the residents was found to be more acceptable. Reflecting the literature, the residents felt that the oral examination should be built of standardized questions and the anticipated answers should be pre-determined. The examination should cover a wide spectrum of subjects, with a restricted amount of time for each answer. A majority, 77% of the seniors and 64% of the residents, agreed that there was something to be learned about the abilities of the examinee from the presentation of a few case studies, and it was felt that this should be added to the revised examination. Only competent examiners should participate and each should rate the examinee independently. An observer from the same program was preferred. The majority of the responders also preferred a high quality and valid examination and did not like to view the examination as a barrier to entering the profession.

From case-based reasoning to problem-based learning.

Many medical schools today are questioning whether they should implement a problem-based learning (PBL) curriculum. Educators have raised serious questions regarding the efficiency of PBL and therefore recommend learning more about the cognitive processes developed by PBL before implementing it broadly. In addition, it is important to determine whether PBL best matches the human reasoning process. The authors' theoretical discussion examines the relationship between the case-based reasoning (CBR) model and the PBL model. CBR indicates that the knowledge source one uses while solving a new problem includes not only generalized rules or general cases, but often a memory of stored cases recording specific prior episodes. CBR enables the reasoner to recommend solutions to problems quickly and to propose solutions in domains that are not completely understood, such as medicine. The authors' analysis reveals a strong association between the CBR and PBL models, and thus it can be argued that PBL is a successful teaching method that should be encouraged by medical schools.
