Abstract
The purpose of this study was to investigate how middle and high school students represent circuit diagrams with different shapes but electrically same. What prototypes of circuit which students possessed were, how students represented the connection of resistors, and what criteria used while grouping the circuit diagrams were investigated. The participants were 10 middle and 10 high school students. The results show that they represented the circuit diagrams by the geometrical resistor configurations rather than physics principles, not considering the presence of a junction or a battery on the branch. This representation was constrained by the circuit prototypes. Middle and High school students seems to have the own way of representing circuit diagrams without considering physics principles.
