Abstract
Background: There are practical difficulties to show exact clinical symptoms such as seizure to medical students at Clinical Performance Examination (CPX). We developed a new CPX case of child's seizure on video using smartphone. Methods: A total of 356 $4^{th}-year$ students of five universities in Daegue-Gyeongbuk and Gyeongnam area took the clinical skill examination from June $13^{th}$ to $17^{th}$ in 2016. Among them, 72 students took the new CPX case in June $15^{th}$ and 71 students filled out the questionnaire on whether the new CPX with smartphone video is helpful, authentic, difficult, and necessary for other CPX. All the questions were measured on 5-Likert scale. Results: Mean score of the new CPX was 57.1, lower than the mean scores of the other 11 CPX cases, 62.8. For the question "Smartphone videos helped to solve the problem", 45 students (63.4%) answered 'Very much'. For the question "Is it realistic compared to other questions?" 30 students (42.3%) and 25 students (35.2%) answered 'Very much' and 'Much'. For the question "Is it difficult compared with other questions?" 18 students (25.4%) and 26 students (36.6%) answered 'Very much' and 'Much'. As for the question "I would like to have more tests using smartphone video", 26 students (36.6%) answered 'So and so'. Conclusion: A majority of students responded that video presentation was helpful and authentic to figure out the CPX, whereas they assessed smartphone video was more difficult compared with other CPXs. Further, students were negative toward using smartphone video for the other CPXs.
