Thanks for your posts everyone. High-fidelity means life-like. High-fidelity manikins are the high-tech manikins (SimMan, MEDI) that can be computer programed to show vital signs on a monitor, drop BP, change cardiac rhythms. Catheters can be inserted, IV fluids can be infused and the instructor can use voice over-technology to seem like the manikin is speaking. I agree that reflection differs from debriefing. Here are a few more questions for anyone to answer: How does reflection differ from debriefing? When you reflect on a simulation, what is going on in your mind? How important is the role of the instructor in facilitating reflection? What is helpful? What is not? Again, I appreciate your time in answering these questions. Hopefully, one day there will be a "model of communication" that Care1 spoke of in the post!
