Understanding the basic concepts of electricity represents a major challenge to most students in K-12 education. Learners find it particularly difficult to develop a robust understanding of potential and potential difference and often believe that the electric current is “used up” by devices. A promising way of making circuits more accessible to students in introductory electricity lessons is offered by the use of analogies in combination with simulations. We therefore developed a new, analogy-based simulation of simple electric circuits. The simulation is intended for use in combination with the bike chain and the air pressure analogies, the implementation of which has been shown to support students’ development of a conceptual understanding of simple DC circuits. Teachers and students can access the 3D simulation free of charge using a modern browser.

An Analogy-Based 3D-Simulation for Teaching Simple Electric Circuits

The abstract nature of electricity makes it a particularly difficult subject for learners to form scientific understandings of the core concepts. One possibility of making such abstract concepts more accessible is using analogical teaching methods. In light of this, a syllabus was developed focusing on the analogy between the movement of charge due to potential difference and the movement of air due to pressure difference. Trials of this syllabus in German grammar schools show a significant improvement in learning gains when compared with traditional approaches. Learners’ qualitative understanding is scaffolded using helpful language, color-coding the electric potential and links to familiar, everyday experiences. The materials used in the previous study have been translated into English and adjusted for use in public schools. Furthermore, additional materials to help structure lessons for less experienced and non-subject-specialist teaching staff are included in lesson packs. All materials will be made available free of charge.
