SILENT PANDEMIC

Abstract

Our study aims to investigate the effect of CO-2 accumulation during lessons, considering factors such as student density, classroom size, and inadequate ventilation, all of which can impact academic performance. To this end, we conducted a practical investigation designed to address the following research question: “Can the accumulation of CO-2 from students’ respiration affect academic performance in the absence of ventilation?”

The proposed hypothesis states that high student density and poor ventilation in the classroom lead to an excess of CO-2 in this physical space, which negatively affects students’ concentration levels.

The objective of our work is to contribute to a better understanding of internal school factors that influence students’ academic performance. Specifically, we examined aspects of classroom ventilation (CO-2 accumulation) and their relationship with students’ concentration during lessons.

As a result, we observed a significant effect of ventilation and student density on CO-2 accumulation during lessons. This provides evidence of a significant correlation between CO-2 accumulation and students’ attention, indicating a reduction in concentration as CO-2 levels increase.
