Abstract
"Integrated Science A" was set as a new science course of study in 1998. In order to achieve the purpose of the "Integrated Science A", a teaching module of the "Integrated Science A" was developed. The developed module was practiced in the classroom, and an educational assessment was carried out. It is proposed that the STS approach should be implemented in "Integrated Science A" lessons dealing with the Natural Environment and Material Change. Through such lessons, the science knowledge acquired by science study was related to a student's daily life, and was not only understood, but also led to an understanding of the global environment which is one of the purposes of STS. In addition, the validity of the developed curriculum was examined and verified.
