Automated problem and solution generation software for computer-aided instruction in elementary linear circuit analysis

Initial progress is described on the development of a software engine capable of generating and solving textbook-like problems of randomly selected topologies and element values that are suitable for use in courses on elementary linear circuit analysis. The circuit generation algorithms are discussed in detail, including the criteria that define an "acceptable" circuit of the type typically used for this purpose. The operation of the working prototype is illustrated, showing automated problem generation, node and mesh analysis, and combination of series and parallel elements. Various graphical features are available to support student understanding, and an interactive exercise in identifying series and parallel elements is provided. When fully developed this engine will be incorporated into a tutorial system designed to supplement conventional instructional approaches.
