目前我国电视教学逐步普及,曾有调查报告说明电视大学学生视力不良率较一般大学的高,而电视教室在自然照明下,课桌面照度以多少为宜,照度过多或过低时对学生视功能有何影响等有关卫生学问题,国内研究较少。本课题是卫生部六·五规划研制项目“电化教育卫生标准”中的一个分题。在“电化教育卫生标准”研究组的安排和指导下,我们于1982年11月至1983年10月在广东佛山电视大学分校,对上述问题进行专项调查研究,为改进电视教学卫生提供科学依据,现将测试结果报告如下:

There was a survey report that shows that the TVU students have a higher visual acuity defect rate than the average university. However, under the natural illumination, the number of desk surface illumination in a TV classroom should be appropriate.

This topic is a sub-topic in “Sixth Five-Year Plan Development Project of Ministry of Public Health”. Under the arrangement and guidance of the research group of “Electrified Education Health Standards”, we conducted a special investigation and study on the above issues from November 1982 to October 1983 at the branch campus of Foshan TV University in Guangdong Province, providing scientific basis for improving TV teaching health. The test results are reported as follows:
