During they interacted with simulation, each dyad received an experimental work sheet and was assigned to complete the work sheet within 60 minutes. To explore their learning performance with simulation, the researchers analyzed and interpreted their worksheet and found that most of them are able to interact and then extracted scientific understanding of electricity from the simulation. However, a few of them still encountered with difficulty to learn with the simulation. Figure 5 illustrates examples of the preservice physics teachers’ experimental data sheet obtained from the interaction with simulation.
