Visual Data

The visual inputs we receive can be collectively called visual data. Precisely how one defines visual data is a key question to ask. That is one of the questions we asked each author who wrote a chapter for this book. If one comes to a decision with respect to what visual data are, then the next question becomes, "What are visual data like?" Then, "What do they mean?" As with any data, we can collect it and compile it, but if we don't have some way to bring meaning it, it has little value to us. The answers may not be as straightforward as one might assume at the outset.
The extent to which visual data permeates what we do as educators is such that it may be difficult to identify every discipline in which it emerges. In this book, we have tried to provide a forum for authors from a cross section of common disciplines: visual arts, English, literacy, mathematics, science, social science, and even higher education administration.
