【 摘 要 】

Chemistry is the subject which includes properties, change, and composition of matter. Chemistry has the system which explains observable properties and change with microscopic level, it explains them using scientific theory andlaws. In the national-level curriculum, the properties and changes of matter are continuously dealt with from elementaryschool to high school, and the curriculum are organized so that students could strengthen their understanding about matter. Inother words, understanding of the properties and changes of matter is the base to explain everyday life with the view of chemistry, and these two are classified as domains of chemistry in the 2015 revised science curriculum. In this study, we confirmedstudents’ understanding about properties of matter and change of matter, through the analysis about results of the NationalAssessment of Educational Achievement (NAEA). For that purpose, this study analyzed the 12 items about properties of matter, and 19 items about change of matter, which were used in the NAEA from 2015 to 2019. According to the results of classifying and analyzing questions according to the core concept, the understanding about the two domains significantly changedbetween the proficient achievement-level students and basic achievement-level students. Depending on the achievement-level,there was a difference in explaining the phenomenon by using the perspective of particles, and by associating scientific concepts and models, or there was a difference in understanding the inquiry related to these two domains. Based on this analysis,this study discussed some implications to be improved on teaching-learning for ‘properties of matter’, and ‘change of matter’.
