摘要

摘要: 目的探索电子屏幕教学方式下教室空间环境对学生视觉健康的影响，为建立适应教学信息化发展的教室空间环境提供科学参考。方法 2024年1月，从内江师范学院招募48名18~21岁本科大学生，采用视觉疲劳评价指标评估亮度、亮度对比度、视看距离、视觉任务时长和眩光对大学生视觉疲劳的影响，通过多元线性回归分析不同指标与视觉疲劳之间的关系，采用准则间相关性权重法客观赋权方法确定不同指标的影响权重。结果多元线性回归分析结果显示，亮度、亮度对比度、视看距离、视觉任务时长和眩光对大学生视觉疲劳影响均有统计学意义(R²值分别为0.91，0.94，0.99，0.99，0.98，P值均 < 0.05)。屏幕亮度在200~400 cd/m²，亮度对比度为6∶1时视觉疲劳程度最低，第3~5排区域的视觉距离有更好的视觉舒适性，视屏任务时间越长视觉疲劳程度越高。在权重方面，教室照明导致的屏幕眩光对视觉疲劳影响最大(24.09%)，其次分别为视觉任务时长(23.41%)、视看距离(20.80%)、亮度对比度(17.81%)、亮度(13.89%)。结论电子屏幕教学导致教室空间环境变化，与学生视觉疲劳有密切关系。

Abstract: Objective To explore the influence of classroom space environment on students' visual health under the teaching mode of electronic screen, so as to provide a scientific reference for establishing a classroom space environment that adapts to the development of teaching informatization. Methods In January 2024, 48 college students aged 18-21 were recruited from Neijiang Normal University. And visual fatigue evaluation indexes were used to assess the effects of brightness, brightness contrast, visual distance, visual task duration and glare on visual fatigue among college students. The relationship between different indexes and visual fatigue was obtained through multiple linear regression analysis, and the influence weights of different indexes were determined by the objective weighting method of criteria importance through intercriteria correlation (CRITIC). Results The results of multiple linear regression analysis showed that brightness, brightness contrast, visual distance, visual task duration and glare had significant effects on visual fatigue among college students (R²=0.91, 0.94, 0.99, 0.99, 0.98, P < 0.05). When the screen brightness was 200-400 cd/m² and the brightness contrast was 6∶1, the visual fatigue degree was the lowest. The visual distance of the third row-fifth row area had a better visual comfort. The longer the visual task time, the higher the visual fatigue degree became. In terms of weight, screen glare caused by classroom lighting had a greatest impact on visual fatigue, accounting for 24.09%, followed by visual task duration (23.41%), visual distance(20.80%), brightness contrast (17.81%), and screen brightness (13.89%). Conclusion The change of classroom space environment caused by electronic screen teaching is closely related to students' visual fatigue.
