寒冷地区过渡季教室环境质量对学习效率的影响研究
Study on influence of classroom environmental quality on learning efficiency in transition season in cold zone
摘要：
为探究寒冷地区过渡季教室环境质量影响学生学习效率的主次因素,将人体主观感受与认知能力测试相结合,在西安市某高校模拟教室环境中,设计了温度、CO2浓度、O2浓度的三因素、三水平正交实验,研究了受试者在不同工况下对环境的主观评价、人体生理参数及学习效率的变化。结果表明,影响学生主观评价、生理反应、学习效率的3个因素主次顺序为:温度、CO2浓度、O2浓度。采用极差分析法从9种工况中得到了最佳实验工况S4(温度为23 ℃,CO2体积分数为600×10-6,O2质量分数为24%),并通过层次分析模型验证了其准确性。
Abstract：
To explore the primary and secondary factors of classroom environmental quality affecting students’ learning efficiency in the transition season in cold zone,combining human subjective perception with cognitive ability test,three-factor and three-level orthogonal experiments of temperature,CO2concentration,and O2concentration are designed in the simulated classroom environment of a university in Xi’an.The changes in subjects’ subjective evaluation of the environment,human physiological parameters,and learning efficiency under different operation conditions are studied.The results show that the primary and secondary factors affecting students’ subjective evaluation,physiological reaction,and learning efficiency are temperature,CO2concentration,and O2concentration.The best experimental condition S4(temperature 23 ℃,CO2volume fraction 600×10-6,O2mass fraction 24%) is obtained from nine operation conditions by the range analysis method,and its accuracy is verified by the analytic hierarchy process model.
