The purpose of this study is to develop and applicate textbook relevant to school indoor air quality. To achieve the purpose, concrete study process are as follows. First, the survey research to teachers, supervisors, and students is conducted to grasp cognition of subjects in elementary school and management situation about school indoor air quality. Second, contents relevant to indoor air quality on textbooks in the 7th elementary curriculum and subsidiary textbooks is analysed through reference study. Third, environmental textbook relevant to school indoor air quality for 5th and 6th grade in elementary school is developed, applicated, and inspected its effect on the basis of implications from results of survey and reference study. The results of this study are as follows. First, the result of survey concerning school indoor air quality showed that three groups had negative attitude for its management even though they thought that it affected human's health and study by and large. Student group thought that each of students itself was a little influence to school indoor air pollution though all of three groups answered that' activities of students' was its main source. Efforts of students to improve school indoor air quality was not much, and its main reason was that they didn't know about school indoor air pollution well.

And it trended to be included to subsidiary textbooks. However, education textbooks about indoor air for elementary students was insufficient still. Third, environmental textbook relevant to school indoor air quality for 5th and 6th grade in elementary school was developed. It was constructed for themes - importance, sources, effects, and management of school indoor air quality. After its application to the 6th grade students in elementary school, it was meaningful in the level of p<.05 that the result of knowledge and awareness in the pre-post test within experiment group. However, all of the results in comparison group didn't represent statistically meaningful difference. In conclusion, environmental textbook developed by necessity of education about school indoor air quality will play a role as useful tool for the 5th, 6th grade students in elementary school to understand relation of quality of health and life and school indoor air quality, to have attitude to make an effort to manage it by develop right awareness about it.
