Text: Disorder/Concept - Third spacing
  1. What is the topic I learned something new about? Be specific and select only one disorder or concept to focus on. Do not report on basic anatomy and physiology. Make sure to provide enough detail for the group to learn just as you did.
  2. What is it that is new and interesting? Why is it interesting and how do you plan on applying this newfound knowledge?
  3. What are the implications for our understanding of anatomy, physiology, and disease?
  4. How might we explain this to the public? Since the public has limited medical knowledge, consider how you would explain these complex concepts to them in a way they will understand.
  5. What are a couple of key things that we should take away from the topic/theme? If you were to select 1-2 things that you would hope we remembered, what would they be?
