理科教育における科学史の取扱い ―Case Historyの必要性とその一例―

抄録

It is generally known, science history is very effective, if it is used for science teaching. So that, the author investigated the treatment of science history in the textbooks on Japanese science education, from past to present. In result, it became clear that science history was almost never used on science education up to the present day, except a period from 194 7 to 1952. If it was used for science teaching, it was generally used to motivation. Because, most of materials were the lives of famous scientists, but a few cases of their study. The present day, it seems science teachers request many cases that is process of research about electrolyte, solution, concept of energy and so on. So the author shows an example, how did chemists study of chain mechanism about decomposition of hydrogen peroxide. In this case, early of the study, interesting facts can be discovered, that is "Idea of child follows process of scientist's research". Of course, this case history of study is insufficient data, but addition of many opinions will be substantial the contents. This kind of study is expected to be used more often on science teaching in the future.
