Rules

1. Teach epidemiology

2. As a group, create a 20-minute lesson during which we will develop a deeper understanding of an enduring epidemiological understanding.

3. Focus on the portion of the unit that is assigned. Use that portion of the unit as the starting point for creating your 20-minute lesson.

4. When teaching assume the foundational epidemiological knowledge from the preceding days of the workshop.

5. Try to get us to uncover the enduring epidemiological understanding. Try to only tell us something when absolutely necessary.

6. End each lesson by placing it in the context of the appropriate enduring epidemiological understanding.

7. Be certain that the lesson is taught in 20 minutes or less.

8. Teach epidemiology.

They can then use that ability to think about their own thinking … to grasp how other people might learn. They know what has to come first,

and they can distinguish between foundational concepts and

elaborations or illustrations of those ideas.

They realize where people are likely to face difficulties developing their own comprehension,

and they can use that understanding to simplify

and clarify complex topics for others, tell the right story, or raise a powerfully provocative question.
