科学的な環境教育を目指した大気環境に関する体験学習の試み

―地方環境研究所を活用したプログラム開発―

抄録

  We developed an experience-based learning program about atmospheric environment focusing on suspended particulate matter (SPM) utilizing the investigation techniques of a Local Government Environmental Research Institute. This program was tested on children and students, and we conducted a questionnaire survey on them before and after this program for evaluating its educational effect.

  First, we devised a method for simplified measurement of the concentration of SPM using standard filters (based on known SPM concentrations). The accuracy of this method was considered sufficient for measuring the concentration of SPM for the learning program. Second, we developed an instruction manual and teaching materials, which aimed to allow participants (1) to judge the actual condition of air pollution objectively from measured scientific data, (2) to realize the differences in SPM according to location, and (3) to discuss the reasons for any differences, and spontaneously grasp the relationship between air pollution and human activities.

  The participants seemed to judge the state of air pollution objectively by comparing their measurement data with environmental standard and the data measured in different areas. This was reflected in the questionnaire results. Additionally, participants demonstrated a deep understanding by discussing how various factors, such as traffic, wind direction and velocity, might influence SPM. They also seemed to understand the relationship between living activities and air pollution. This understanding probably improved the sense of individual environmental impact, and the improvement was reflected in the questionnaire results. Our learning program will contribute to the development of a scientific view, logical thinking skills and the awareness of environmental conservation.
