Abstract
Research-based tips for improving your students' sub-microscopic understanding of particle models. Johnstone's triangle summarises levels of representation regularly used when thinking about chemical concepts. Of the three levels, the sub-microscopic is probably the most important for understanding or explaining how chemical processes occur. A student's understanding of how the sub-microscopic level is visually represented, for example in diagrams, is directly linked to their understanding of the underlying chemistry concepts.
