青岛市某小学教室光环境现状调查

The Investigation for the Current Situation of Light Environment in the Classroom of a Primary School in Qingdao

为了解低年龄段小学生教室光环境现状,分析小学生对光环境的特殊需求,本研究对青岛市某小学1~6年级共10个班级的教室光环境进行了现场实测,同时对实测班级的353名小学生进行了室内光环境评价问卷调查。结果显示,各班级课桌面平均照度的合格率为80%,课桌面照度均匀度均不达标。各班级黑板面平均照度的合格率为50%,黑板面照度均匀度的合格率为10%。室外自然采光会对课桌面和黑板面平均照度与照度均匀度造成影响;问卷调查中,97%的小学生认为教室光环境适中,93%的小学生对光环境感到满意或非常满意,88%的小学生没有改变光环境现状的期望。总体上,小学教室课桌面和黑板面平均照度与照度均匀度达标率较差,受自然采光干扰较大,应对教室光环境进行改造升级。大部分小学生对教室光环境感到满意,存在小部分学生对光环境感到不满意,应重点关注这部分对光环境不满意的小学生,避免他们发展成为视力不良症。

The indoor light environment is one of the most important factors for the development and stability of vision,especially for students in primary school who are in the stage of rapid growth and development.However few studies have been performed to explore the light condition in the classrooms for low-age pupils.If there are any special needs from pupils for the light environment that is still under-investigated.The present study was thus conducted by conducting on-site measurements in a total of ten classrooms covering all the grades in primary school.Subjective perceptions of the light in the classroom were also collected by tailored questionnaires.The results showed that the illuminance on 80%of desktop and50%of the surface of the blackboard comply with the standards,but the uniformity for the former did not meet the standards and for the latter only 10%follow the stipulations by standards.97%of students rated the classroom light environment moderate,and 93%of students were satisfied with the classroom light environment,and 88%of students did not expect to change the current light environment.The study suggests that the uniformity in the classrooms are poor,and the illuminance on the blackboard surface needs to be improved.The light in the classroom is greatly disturbed by natural lighting.Most students are satisfied with the light environment in the classroom,while a small number of students are dissatisfied with the light environment.More attention needs to be put on these pupils to prevent them from developing poor vision.
