Whenever I taught about the particulate nature of matter in solids, liquids and gases, I often had difficulty explaining this abstract concept to my students. The students, in turn, had much difficulty conceptualizing the structure and behavior of the particles, which ultimately led to difficulties in understanding the complex configuration of particles in matter at various levels. This article focuses on studies that reveal students’ alternative frameworks for the particulate nature of matter in solids, liquids and gases. Also, I suggest factors that contribute to these alternative frameworks, incorporating my own experiences in developing an understanding of this concept. Finally, in light of these alternative conceptions and difficulties, I consider strategies for effectively teaching this abstract concept.
