Four Ways to Use Graphics to Four Ways to Use Graphics to Promote Learning:Promote Learning:
1. Use graphics to teach five different types of content such as facts, concepts, processes, procedures, and principles
2. Use graphics as topic organizers3. Use graphics to show
relationships4. Use graphics as lesson interfaces
