Abstract:Abstract: OBJECTIVE To grasp the current situation of teaching environment in primary and secondary schools in Haishu District and promote the improvement of teaching environment.METHODS 168 classrooms in 7 primary and secondary schools were randomly selected from 2021 to 2024,and the monitoring results of indicators such as lighting were evaluated in accordance with relevant school hygiene standards.RESULTS The total qualified rate of each index within four years was between 20.14%and 94.05%.The reflectivity ratio of the blackboard surface was the lowest in 2023 and 2024,at only 8.33%,while the lluminance uniformity of blackboard suface in 2022 could reach 100.00%.The overall situation in junior high schools was the best,while that in primary schools was relatively poor. Thedifferences among the per capita classroom area,the coincidence rates of desk and/or chairallocation,the averageilluminances of blackboard surface and desk surface were statistically significant(x²=23.776,228.359,189.845,118.456,36.655,20.499;P<0.05).The qualification rates ofthe three indicators related to the coincidence rate of desk and chair allocation in street schools were slightly better than those in township schools,and these differences between the two were significant(x²=9.645,33.574,16.692;P<0.05),while the qualified rate of blackboard reflectivity in street schools was 4.17%,which was significantly lower than that in township schools(23.33%), and the difference was statistically significant(x²=4.568,P<0.05).CONCLUSION The overall situation of teaching environmental hygiene in primary and secondary schools in Haishu District is at a medium to high level,but there were still some indicators with relatively low pass rates.Itneeds to be taken seriously and improved by relevant departments.
