Purpose: The main purpose of this study was to compare the effects of OSCE method and traditional evaluation method on nursing skills performance of students for the fever client. Method: The study was designed as a quasi-experimental, nonequivalent control group post test design with two classes of sophomore students attending fundamentals of nursing courses at one baccaleureate nursing school located in a metropolitan Seoul area. Control group was evaluated by using a traditional method and the experimental group was evaluated by using the OSCE method. Data were collected from April, 2001 to November, 2002. There were 35 students in the OSCE method group, 39 students in the control group. Data analysis was done using SPSS WIN 11.0. Result: The results showed that the students in the OSCE method group did significantly better in clinical nursing skills performance than the students in the traditional method group. And the OSCE method group showed significantly higher satisfaction score in the evaluation method than the control group. Conclusion: The OSCE method is an effective in evaluating clinical nursing skills performance for student nurses. It is necessary to explore more reliable ways to compare the evaluation method by the same student. Also, it is recommended to replicate similar studies in nursing education.
