Use graphics to present meaningful contexts for learning. Attention is naturally drawn to what is novel or different. Presentation Graphics Graphics should be congruent and relevant to the information presented in the text. Graphics should be prepared to clearly represent the content that is to be remembered. Students should be cued to process the information contained in a graphic in some overt way.
Graphics are unnecessary when the text alone produces mastery.
Use graphics to show major points or headings. Use illustrations and videos to reinforce your educational materials. Graphics are not necessary when the text already prompts the learner to spontaneously form internal images. Make visuals landscape, not portrait on screen. The principle of aestheticism includes simplicity, boldness, contrast, and color.
