Abstract

The aim of the research was to identify how Slovenian primary and secondary school students of various age groups explain the particulate nature of the states of matter of water and air. The qualitative research included five 12, 14, and 16 year old students. A semi-structured interview including four computer-displayed tasks was used for the data collection. The research results show that all of the students correctly identified the states of matter of water at the particulate level, but not of air. It was found that the students had difficulty justifying their selection. The study confirmed the existence of: (a) misunderstanding regarding the interpretation of the particulate nature of matter, (b) a failure to distinguish between particle and matter, and (c) the inadequate description of submicroscopic level of matter with macroscopic level concept. The survey results provide an insight into the mindset of students and serve as a starting point for teachers’ lesson planning.
