Visual literacy is the ability to recognize and understand messages that we see with our eyes -- usually non-verbal messages. The message above -- while using no words -- clearly says "No Smoking." The ability to decode that message is the definition of visual literacy.
While there is mixed informational about whether learning styles are legitimate, I know that some of my students learn easier when they see something. Visual representations are critical components of any lesson -- wither face-to-face or virtual because it provides a alternate way of clarifying material. eLearning, students are not able to see my gestures and facial expressions so appropriate graphics are critical. When you go to a foreign country and you don't know the language, you rely on sign and other non-verbal communication to help you get around. It is the same with eLearning. Graphic signs help us find our way.
