Visual Literacy

This e-learning site focuses on a critical, but often neglected skill for business, communication, and engineering students, namely visual literacy, or the ability to evaluate, apply, or create conceptual visual representations. After this tutorial, students should be able to evaluate advantages and disadvantages of visual representations, to improve their shortcomings, to use them to create and communicate knowledge, or to devise new ways of representing insights.
