Explain the process to your students of what will be covered in the simulator situation. You should explain what will happen as if it will take place in real life. This includes the process and protocols, the dangers and hazards, as well as the reasons behind performing the steps.
Begin the simulation. Take the pace slow so that you can show your students what the screen should look like when they are going through the simulation.
Stop frequently to make your various points of your lesson. Let the students watch you complete the task first if it is a difficult simulation.
Offer tips and praise when the task is complete. You can quiz the students on what they learned throughout the simulation if desired.
