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)系统应用于基础护理技能教育。包括不当护理行为在内的几个视频被制作在系统中使用。护生们可以反复观看视频，并写出他们在视频中发现的错误。我们为视频编写了一个场景，扮演病人和护士的角色。两台数码摄像机被用来拍摄视频。视频被电脑剪辑成9分钟长的电影。我们已经拍摄了四部电影，分别是《定位病人》、《血压读数》、《血压读数》和《注射准备》。视频点播系统由快速以太网局域网、视频服务器和41台客户端计算机组成。41名学生可以在同一张图片中重复看到左侧页面上的视频，并在右侧页面上写出报告。我们将该系统应用于我校的护理基础技能教育，并通过问卷调查的方式对其进行评估。结果，护生认为该学习系统是有用的。在这次练习中，每个学生都比集体观看时更专心地观看视频。实践证明，VOD系统对护生的学习效果良好，提高了护生的学习动机。

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.
