When you have several diagrams from different sources, students will compare them and discuss them using the following questions as starting points: What are some similarities and differences between different diagrams? Which diagrams do they think are the easiest to understand and the hardest to understand? What techniques have the illustrators of the better diagrams used to make their work clearer?
