夏季室内二氧化碳对学习效率的影响研究

Study on the effect of indoor carbon dioxide on learning efficiency in summer

教室环境质量直接影响室内人员的身心健康和学习效率。研究在夏季24℃下CO2浓度对学习效率的影响。采用主观问卷和学习认知能力测试的方法,测试了不同CO2浓度下受试者的各项主观评价和学习效率,得出了学习效率在不同CO2浓度下的变化情况。结果表明:不同CO2浓度下,受试者的正确率、反应时间和学习绩效的变化存在差异;CO2浓度对不同测试项目的正确率、反应时间和学习绩效等指标的影响程度存在差异;整体学习效率随着CO2浓度的升高而降低。

The quality of classroom environment directly affects the physical and mental health and learning efficiency of indoor personnel.The paper studied the effect of carbon dioxide concentration on learning efficiency at 24℃.Subjective questionnaires and learning cognitive ability test methods were used to test the subjective evaluation and learning efficiency of subjects with different CO2 concentrations,and the changes of learning efficiency under different CO2 concentrations were obtained. The results showed that there were differences in the correct rate,response time and learning performance of the subjects under different CO2 concentrations;the influence of CO2 concentration on the accuracy,reaction time and learning performance of different test items was different;In other words,learning efficiency decreases as the CO2 concentration increases.
