This is a generic rubric I use when I group students to do peer teaching.
For example, after teaching terms for a unit, I will group students. Each group is required to show the assigned terms in their application. They can present this information in anyway they want. I have at least one group that raps the information every week! Some use posters, some use PowerPoint, etc.
The rubric makes sure they each assign themselves a group role, define their goal, teach all the points required, be attentive to other groups, and even assess that their classmates understand what was taught.
