The document discusses six principles of visual graphic design for instructional materials: 1. Contrast - Use sufficient contrast between elements so they are easily distinguished. 2. Alignment - Arrange elements in a parallel, organized manner. 3. Simplicity - Keep the message simple with only necessary text and graphics to avoid distraction. 4. Proximity - Leave appropriate space between elements to suggest relationships. 5. Emphasis - Have one main focal element to draw attention. 6. Repetition - Use repetition sparingly and only if needed for consistency.
