Many have argued that hypertext is a communication medium that
requires its own rhetoric. According to Karen Schriver (1997),
the conventions of such a rhetoric are currently under construction.
As a result, document designers are "groping through the design
space and inventing as we go" (p. 379).
The following views support the notion that hypertext requires
its own rhetoric:
Henrietta N. Shirk (1991) argues for a special set of rhetorical
principles for evaluating the effectiveness of hypertext. This
rhetoric should include:
A description of how various cognitive structures effectively
convey information and rules for applying these structures
Principles of good screen design
The creation of meaningful metaphors within electronic spaces
Gary Heba (1997) has defined a rhetoric of multimedia communication
called "HyperRhetoric" that includes hypertext as one of its rhetorical
elements.
He writes: "Traditional models and approaches to written communication
are inadequate for explaining the rhetorical phenomenon of multimedia
and for preparing students to become multimedia literate because
these models do not adequately describe the rhetorical space of
electronic documents" (p. 21).
Print writing occupies the rhetorical space of pages while multimedia
occupies the space of "screens, speakers, keyboards, mice, and
headsets." The traditional models and approaches do not help us
learn to "produce linked screens of virtual discourse" that are
necessary in this electronic space (p. 21).
Kathleen McCabe (1997) states that hypertext ultimately requires
its own rhetoric because the complexity involved in writing hypertext
is much greater than writing traditional text.
She argues that whether a writer composes for paper or the screen,
many rhetorical issuesthe appropriateness of the medium, audience
analysis, purpose, organization, and document designare the same.
Nonetheless, in addressing these issues, the hypertext writer
still finds more differences than similarities. Hypertext ultimately
requires its own rhetoric because the complexity of the task is
much greater online than in print.
In essence, hypertext writers "are not just writing but are more
accurately designingthat is, creating logical nodes of information,
connecting those nodes, constructing an interface, and programming"
(McCabe, 1997). They are "designers who work toward a synthesis
of visual and verbal rhetoric" (Kolosseus, Bauer, & Bernhardt,
1995, p. 80).
Tovey (1998) says a major reason for rhetorical differences between
online and print documents is that screen displays can create
reading problems.
Screen reading problems require thoughtful design decisions (Haas, 1989). Thus, designers
need to consider rhetorical issues differently than they would
for conventional texts.
