The conducted studies showed that the degree of fatigue of the 10-grade students at the lessons on the basics of information science and computing technology was determined by the duration of work with video terminals. Thus, the general length of work with displays in the IIId class should be limited by 30 min: 20 min at the beginning of the lesson and then 10 min later the complex of physical exercises for general and visual fatigue unloading. More prolonged with displays resulted in deterioration of students'++ body functional state and decrease of their work capacity.
所进行的研究表明,十年级学生在信息科学与计算技术基础课程上的疲劳程度取决于使用视频终端的时长。因此,三年级课程中使用显示器的总时长应限制在30分钟:课程开始时20分钟,然后在随后的10分钟进行一套针对全身和视觉疲劳缓解的体育锻炼。使用显示器时间过长会导致学生身体机能状态恶化以及工作能力下降。
