THE ASSESSEENT AND DEVELOPMENT OF A VIDEO-ON-DEMAND SYSTEM IN THE EDUCATION OF BASIC NURSING SKILLS

我们将视频点播（VOD）系统应用于护理基础技能教育。制作了包括不当护理行为在内的若干视频，供系统使用。护理专业的学生可以反复看视频，并就他们在视频中发现的错误写报告。我们为视频写了一个场景，扮演了一个病人和一个护士的角色。使用两台数码摄像机拍摄视频。这段视频用电脑剪辑成9分钟长的电影。我们制作了《病人定位》、《血压读数准备》、《血压读数准备》、《注射准备》四部电影。每部电影都包括四种不正确的护理行为。视频点播系统由快速以太网局域网、一台视频服务器和41台客户端计算机组成。41名学生可以反复观看左页的视频，并在同一张图片的右页上写一篇报告。我们将该系统应用于我校护理基础技能教育，并采用问卷调查的方式进行评价。结果，护理专业的学生认为这个学习系统是有用的。在这个实践中，每个学生都比在小组观看时更专心地观看视频。结果表明，视频点播系统对护生学习有一定的帮助，提高了护生学习的积极性。

We applied a video-on-demand(VOD) system to the education of basic nursing skills. Several videos including improper nursing actions were made for using in the system. The nursing students could see the video repeatedly and write reports about the mistakes they found in it.We wrote a scenario for the video and played the role of a patient and a nurse. Two digital video cameras were used for taking video. The video was edited with computer into 9 minutes long movie. We have made four movies entitled "positioning patient", "preparation for blood pressure reading", "blood pressure reading" and "preparation for injection". Each movie included about four improper nursing actions.The VOD system consists of Fast Ethernet LAN, a video server and 41 client computers. Forty-one students can repeatedly see the video on the left page and write a report on the right page in the same picture.We applied the system to the education of basic nursing skills in our school and evaluated it by means of questionnaire. As the results, nursing students replied this learning system was useful. In this practice every students was seeing the video more attentively than in the group viewing. It was confirmed that the VOD system was useful for the nursing students and promoted their motivation for learning.
