Building Black Box Circuit Simulators to Test and Improve Pupils' Problem-Solving Ability
Physics Education Volume 53, Number 5, ISSN 0031-9120
Putting an electrical circuit within an inaccessible black box and asking pupils to deduce what wiring is contained within the box based solely on the circuit's behaviour is a simple teaching idea with a long history. Problems arise when trying to build enough physical black boxes to simulate a larger number of circuits within a typical school's storage limitations. A solution is described which uses a microcontroller to simulate a large number of separate circuits within a single black box.
