A problem-based approach to the teaching of mechanical wave propagation,focused on observation and measurement of wave properties in solids and onmodelling of these properties, is presented. In particular, some experimentalresults, originally aimed at measuring the propagation speed of sound wavesin metallic rods, are used in order to deepen the role of constraints inmechanical wave propagation. Interpretative models of the results obtainedin the laboratory are built and implemented by using a well-known simulationenvironment. The simulation results are, then, compared with experimentaldata. The approach has been developed and experimented in the context of aworkshop on mechanical wave propagation of the two-year Graduate Programfor Physics Teacher Education at University of Palermo.
