Chemistry is the subject which includes properties, change, and composition of matter. Chemistry has the sys- tem which explains observable properties and change with microscopic level, it explains them using scientific theory and laws. In the national-level curriculum, the properties and changes of matter are continuously dealt with from elementary school to high school, and the curriculum are organized so that students could strengthen their understanding about matter. In other words, understanding of the properties and changes of matter is the base to explain everyday life with the view of chem- istry, and these two are classified as domains of chemistry in the 2015 revised science curriculum. In this study, we confirmed students’ understanding about properties of matter and change of matter, through the analysis about results of the National Assessment of Educational Achievement (NAEA). For that purpose, this study analyzed the 12 items about properties of mat- ter, and 19 items about change of matter, which were used in the NAEA from 2015 to 2019. According to the results of classi- fying and analyzing questions according to the core concept, the understanding about the two domains significantly changed between 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 con- cepts 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’.
