Many General Chemistry courses include a laboratory experiment that allows students to explore conductivity to provide insight into the atomic nature of solutions. The goal of this paper is to present the results of a qualitative study designed to examine students’ understanding of the atomic nature of substances before and during conductivity tests. In addition, the talk will address how the results of the study were used to inform the design of an electronic learning tool on conductivity experiments. The nature of the tool will be demonstrated.
