Study on Productivity in the Classroom (Part 3) Nationwide Questionnaire Survey on the Effects of IEQ on Learning Performance

Many research papers have been published on the potential effects of the quality of the indoor environment on productivity in classrooms and offices. This paper (Part 3) reports the result of nationwide field measurements based on subjective questionnaire surveys and objective test scores in a unified way.
It investigated 83 branches of a college, which are located in regions spread throughout Japan. The total number of subjects was about 4000. Objective learning performance was evaluated according to scores in standardized quizzes to measure the level of understanding of lectures. In addition to the objective evaluation using quiz scores, a subjective evaluation of learning performance was carried out using a questionnaire as a self-assessment form.
Percentage of dissatisfied of each schoolhouse did not have the correlation with quiz scores but had a significant correlation with a subjective evaluation of learning performance by a linear approximation (p<0.006).
