Education graphics, or edugraphics, are graphic visual representations of educational information intended to simplify social-cultural content, communication related content, linguistic content, etc. The use of rich visual content improves cognition, as the students comprehension is enhanced when both visual and text-based cues are combined.
Edugraphics have existed since learning manuals began to be used in elementary schools, high schools and universities. These edugraphics, known by the term infographics or "information graphics", are used to explain different subjects (geography, history, science, biology...). They were used to illustrate some aspect of the lesson (map of invasions, timelines, internal organs, etc.), and they were drawn or made by computer graphics.
