To improve the viewing of the video-projected structured clinical examination (ViPSCE), we developed a computerized version; the computer-based clinical examination (CCE). This was used to assess medical students' higher knowledge and problem solving skills in surgery. We present how we did this, test score descriptive statistics, and the students' evaluation of the CCE.
A CCE in surgery was administered to assess a class of 43 final year medical students at the end of their surgical clerkship. Like the ViPSCE, the exam was delivered as a slide show, using a PowerPoint computer program. However, instead of projecting it onto a screen, each student used a computer. There were 20 slides containing either still photos or short video clips of clinical situations in surgery. The students answered by hand writing on the exam papers. At the end, they completed evaluation forms. The exam papers were corrected manually. Test score descriptive statistics were calculated and correlated with the students' scores in other exams in surgery.
Administration of the CCE was straightforward. The test scores were normally distributed (mean = median = 4.9). They correlated significantly with the total scores obtained by the students in surgery (r = 0.68), and with each of the other exam modalities in surgery, such as the multiple choice and structured essay questions. Acceptability of the CCE to the students was high and they recommended the use of the CCE in other departments.
CCE is feasible and popular with students. It inherits the validity and reliability of the ViPSCE with the added advantage of improving the viewing of the slides.
为了改进视频投射式结构化临床考试（ViPSCE）的观看效果，我们开发了一个计算机化版本；基于计算机的临床考试（CCE）。它被用于评估医学生在外科方面的更高层次知识和解决问题的能力。我们展示了我们是如何做到这一点的、考试分数的描述性统计数据以及学生对CCE的评价。
在外科实习结束时，对43名医学专业最后一年的学生进行了一次外科CCE考试。与ViPSCE一样，考试以幻灯片形式呈现，使用PowerPoint计算机程序。然而，不是将其投射到屏幕上，而是每个学生使用一台计算机。有20张幻灯片，包含外科临床情况的静态照片或短视频片段。学生们在试卷上手写答案。最后，他们完成了评价表。试卷进行人工批改。计算了考试分数的描述性统计数据，并将其与学生在其他外科考试中的分数进行了关联。
CCE的实施很简单。考试分数呈正态分布（均值 = 中位数 = 4.9）。它们与学生在外科考试中的总成绩显著相关（r = 0.68），并且与外科其他考试形式，如多项选择题和结构化论文题的成绩也显著相关。学生对CCE的接受度很高，他们建议在其他科室使用CCE。
CCE是可行的，并且受到学生的欢迎。它继承了ViPSCE的有效性和可靠性，还具有改善幻灯片观看效果的额外优势。
