Impact of indoor environment on learning efficiency in universities during the transitional season
To investigate the correlation between indoor environment and personnel learning per-formance,a typical classroom in a university in Xi'an was selected and continuously monitored for parameters such as indoor temperature and humidity,CO2 concentration,sound level and illumi-nation,and 248 students were subjectively surveyed and field tested for learning efficiency using subjective questionnaires and neurobehavioural ability assessment software.The results show that during the transition season,students as a whole were in a cold but comfortable temperature range,with peak learning performance at 21.5 ℃;Two-thirds of students feel comfortable in en-vironments with CO2 concentration below 1 000 mg/m3 and the mean learning performance re-mained at a high level;Students preferred quiet environments but noise at 60 dB levels had an a-rousing effect on subjects;Brighter environments were more suitable for learning,but brighter than 340 lx could irritate the eyes and make students feel fatigued,resulting in lower learning ef-ficiency;there were differences in the strength of correlations between environmental parameters and the four learning efficiency factors:concentration,perception,logic and memory,with con-centration having a strong correlation with all four environmental parameters.
