Student's Understanding of Alternating Current Circuits

The proposal describes methodologies to study students' understanding of basic AC phenomena and their application in the analysis and troubleshooting of AC circuits and systems. A systematic approach is developed in terms of two complementary strands:

Both these strands are developed through a progression of concepts that start with characterization and understanding of basic phenomena and metaphors associated with these phenomena, then move on to understanding the functionality and behavior of individual components in circuits, and finally deal with system-level analysis and troubleshooting in complex AC systems. This progression will help us better understand and capture misconceptions that arise in the analysis and troubleshooting of AC systems, their origin, and their effects as subjects' deal successively with more complex systems.
