夏季教室内环境质量对学习效率的影响研究
Effect of classroom environmental quality on learning efficiency in summer
摘要：
为探究教室内环境质量对高校学生学习效率的影响,本研究对西安某高校夏季教室内环境进行了实时监测,并将263名高校学生的主观问卷调查与学习效率测试相结合,分析了温度、CO2浓度、风速、噪声、照度和相对湿度6个关键环境参数对高校学生学习效率的影响。结果显示:温度、CO2浓度、风速和噪声对学习效率具有显著影响;在教室内温度为27.5 ℃以下、CO2体积分数低于1 250×10-6、风速约0.35 m/s、照度为350～450 lx、噪声与相对湿度分别不超过55 dB和55%时,受试者表现出学习效率较高;各环境参数对4类学习效率因子的影响存在显著差异,其中温度与4类学习效率因子均有显著相关性。
Abstract：
To explore the impact of classroom environmental quality on college students’ learning efficiency, this study conducts real-time monitoring of the classroom environment of a university in Xi’an in summer, and combines subjective questionnaires of 263 college students with learning efficiency tests to analyse the impact of six key environmental parameters: temperature, CO2concentration, wind speed, noise, illuminance and relative humidity on college students’ learning efficiency. The results show that temperature, CO2concentration, wind speed and noise have significant effects on learning efficiency. In a classroom environment with a temperature below 27.5 ℃, CO2volume fraction lower than 1 250×10-6, wind speed about 0.35 m/s, illuminance between 350 and 450 lx, and noise and relative humidity not exceeding 55 dB and 55%, respectively, participants demonstrate relatively better learning efficiency. There are significant differences in the impact of these environmental parameters on the four categories of learning efficiency factors, with temperature showing significant correlations with all four factors.
