中小学课桌椅高度调节的指导标准探讨

Research on the National Standard for Height Adjustment of Desks and Chairs in Primary and Secondary School

课桌椅尺寸标准GB/T 3976-2014《学校课桌椅功能尺寸及技术要求》发布以来,课桌椅由固定式发展为以可调节桌椅为主流,中小学生的生理状况也发生了较大变化,标准要求相对滞后,本文通过课桌和课椅模拟场景可用性测试与试验数据统计分析,找出学生身高与使用课桌椅最适宜的座面、桌面高度及其匹配性,为课桌椅高度调节提供具有科学依据的指导标准。

The national standard,GB/T 3976-2014,Functional sizes and technical requirements of desks and chairs in schools,has been released for three years.Desks and chairs have been developed from fixed to adjustable ones.The physiological conditions of primary and secondary school students have also changed a lot.However,the requirements of the standard are relatively lagging.This paper simulates the scene usability test and statistical analysis of test data through the desks and chairs to find out the most suitable height of desk and chair,as well as how to match student’s height with the height of desk and chair.This research aims to provide a scientific guiding standard for the adjusting of the desks and chairs.
