Abstract

The concept of the "amount of substance" occupies an important position in modern chemistry for a good understanding of the quantitative relations in chemical reactions. However, the concept is very difficult for senior high school students to understand. Although several teaching aids have been reported by several school teachers and science education researchers in order to provide a better understanding of the concept, it is well known that Japanese high school students do not like the learning content related to the unit "mole". In this study, we first carried out an investigation of teachers and students in order to find out how the "amount of substance" was introduced in their chemistry classrooms. Secondly, we tried the introduction and development of the term "molarity" in relation to "neutralization reaction" in junior high school science. An appropriate treatment of the "amount of substance" is proposed by considering the above results; it is also discussed that introducing particle pictures is important to realize the concept of "unt of substance".
