Classroom Conditions and Student Achievement (10-23-20)

Brink and colleagues evaluated links between college/university classroom conditions and student performance.  They report that their literature review determined that  “Warm white light provides a relaxing environment and supports communication, and should gradually change to blue-enriched white light after its prolonged use during the morning to prevent drowsiness. . . . these different correlated color temperatures imitates the natural change of daylight during the day and therefore supports teachers' and students' circadian rhythm.. . . a lighting system with a color temperature of 4000K in classrooms can also influence the ability to concentrate positively. . . . regulation of students' circadian rhythm is important because it influences students' alert state and cognitive performance. . . . The cognitive performance of students can decline by as much as 13% (P < 0.001) when the CO2 concentration increases from 600 to 1000 ppm. . . . this concentration of CO2 still meets prevailing guidelines.”
