[目的]了解深圳市宝安区中小学校教学环境的卫生状况,发现问题,提出改进措施。[方法]2009年5~10月,分两阶段在宝安区32所中小学,抽取有代表性的教室进行调查,并抽取部分学生测量身高与课桌椅高度。[结果]在32所中小学调查192间教室,测量黑板174块,教室人均面积达标率为71.88%,朝向达标率为78.13%,采光系数达标率为93.23%,玻地比达标率为96.35%,采光方向达标率为96.35%,后墙反射系数达标率为4.17%,桌面照度达标率为98.96%,噪声强度全部超标;黑板课桌距离达标率为42.19%,黑板尺寸达标率为70.69%,黑板反射系数达标率为89.08%;测量学生1 920名,课桌椅配置符合率为10.31%。综合评价得分,18所私立学校为69.49分,14所公立学校为74.87分。[结论]深圳市宝安区中小学教学环境质量存在较多问题,环境噪声和课桌椅配置不符合问题最为突出。
[Objective] To understand the hygienic condition of teaching environment in primary and secondary schools in Bao’an District of Shenzhen City, discover the problems and put forward the improvement measures. [Method] From May to October 2009, 32 representative primary and secondary schools in Bao’an District were selected for investigation in two phases. The height of the students and the height of desks and chairs were also taken from some students. [Results] 192 classrooms and 174 blackboards were surveyed in 32 primary and secondary schools. The per-capita compliance rate of the classroom was 71.88%, that of the standard classroom was 78.13%, that of the lighting system was 93.23%, that of the glass floor was 96.35% , Lighting direction compliance rate of 96.35%, back wall reflection coefficient compliance rate of 4.17%, tabletop illumination standard rate of 98.96%, all of the noise intensity exceeded; blackboard desk distance standard rate of 42.19%, blackboard size compliance rate was 70.69% Blackboard reflection coefficient of 89.08% compliance rate; measuring 1 920 students, desks and chairs configuration in line with the rate of 10.31%. Comprehensive evaluation of scores, 18 private schools for 69.49 points, 14 public schools for 74.87 points. [Conclusion] The quality of teaching environment in primary and secondary schools in Bao’an District of Shenzhen City has many problems.
