Clearly, literacy has always been deictic, its meaning changing in each
of these contexts, and many others, as new technologies appeared and people
envisioned new ways of using these technologies for information and communication.
What is unique about the current period is the technologies and envisionments
for literacy repeatedly change within such short periods of time, affecting
so many individuals. Our era is defined largely by repeated, rapid, and
revolutionary changes in the technologies of information and communication
(Harrison & Stephen, 1996; Johnson, 1997; Negroponte, 1995). Within
just 20 years, we have seen the wide-spread appearance of, among others:
word processing technologies, electronic data base technologies, multimedia/hypermedia
technologies, e-mail technologies, and Internet technologies. Each
has helped to redefine the nature of literacy and each has seen new envisionments
for its use redefine the technology itself.
