Improvement Schemes of STS Contents and Structure of the High School Chemistry I Textbooks to be developed by the 7th Curriculum

摘要

The purpose of this study was to examine for high school chemistry I textbooks published by the 6th curriculum and some foreign STS programs such as Chemistry in the Community, Science and Technology in Society, Chemistry: The Salter's Approach by analyzing STS contents, students' activity, overall structure of the books and space devoted to STS, and to provide improvement schemes for developing high school chemistry I textbooks to be developed by the 7th curriculum in future. It was found that STS topics in the high school chemistry I textbooks were related only to ??social problems and issues?ˉ, ??applications of science?ˉ, ??multiple dimensions of science?ˉ, and STS contents were presented mostly by narration. Students' activities were limited to discussion and survey, and none of the topics were related to ??career awareness?ˉ, and ??cooperative work on real problems?ˉ in high school chemistry I textbooks. On the contrary, a variety of STS topics and activities such as case study related to local and community, practicing decision-making strategies, role play, practical work career awareness were included in foreign STS programs. Desirable directions for the improvement of STS contents and structure of present high school chemistry I textbooks were proposed in this paper.
