I asked each group to create a narrated presentation using either Keynote or PowerPoint, which they then uploaded to a discussion forum in our web-based course management system. Each student also reviewed at least one other group's presentation, providing feedback on content, as well as the application of the Presentation Zen approach. I provided feedback in the forum as well, commenting on the presentations themselves and the peer reviews. Everyone who participated got full credit, which is why I referred to the practice presentation and peer review as a risk-free or low stakes activity.
