Baca (1990) did the most recent and most comprehensive study to date, a delphi study in which visual literacy professionals collectively helped identify what is and what is not a part of visual literacy. After years of quibbling about the nature of visual literacy, Baca found that “There is a great deal of agreement regarding the basic tenets of visual literacy
among the scholars who study it” (p. 74). Baca listed 186accepted constructs of visual literacy. Those regarding definition
included: “Visual literacy refers to the use of visuals for the purposes of communication, thinking, learning, constructing
meaning, creative expression, [and] aesthetic enjoyment” (p. 65). Earlier, Baca and Braden (1990) had pointed
out regarding the Braden-Hortin definition that “even that definition fails to directly address design, creativity, and aesthetics
as they apply to visualization.” The delphi study acknowledged
the additions.
