Do you include text during a phone call simulation?

Hi Abby. The community has pulled together some fantastic ideas here! Adding to this, if the real-life experience you're simulating is predominantly audio, then it's absolutely okay for your phone call simulation slide to be the same. Keeping the slide visual design simple so learners can focus on the audio could be just the right way to guide their attention.

If the slide visual design you have now feels more blank than elegantly simple, all it might take is a few small changes (like including a photo of a call center to set the tone of the activity or a few brief notes about what to listen for in the call) to elevate the design without distracting your audience.
