Building Black Box Circuit Simulators to Test and Improve Pupils' Problem-Solving Ability
Harrison, Mark
Physics Education, v53 n5 Article 055019 Sep 2018
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.
