Reading in a hypertext environment
shares many characteristics with reading in a linear print environment.
Digital text is still text, and not all linear text is always read in a
linear fashion. Reference books, such as dictionaries and encyclopedias,
are not generally read from beginning to end, and some readers read quite
selectiviely in linear text. People have different styles and approaches
to reading in linear text as well as hypertext. Some readers browse,
scan, and scroll through text. Others read thoroughly, while still others
reread and go back over sections of text, underlining, highlighting, or
even making notes in the margin.
Hypertext readers frequently read differently from readers in a linear printed environment. Troffer (2000) cites to research showing that reading from the screen is about 30% slower than reading from paper. However, she notes that most online readers do not go online primarily to read. She says they often tend to scan a document rather than read word for word. Slatin (1991) and Burbules and Callister (1996) describe three types of hypertext readers
A number of studies have been conducted to determine if reading in hypertext has advantages or disadvantages over reading in in a linear printed text environment. The results of these tests are inconclusive. Frequently these studies have focused on tests used to evaluate reading ability in a linear environment and applied these tests to a hypertext environment. Research has shown, however, that online reading can be quite different from linear print reading (Slatin,1991, Burbules & Callister, 1996, and Troffer, 2000). Puntambekar (n.d.)observed that many of these tests focus on
We will always find characteristics that we should not want to associate with reading as such, but are beneficial to the case. Reading is like soup or slime. We should not want to specify its essence according to any neat digital calculus (McHoul & Roe, 1996, Section 5 Just Reading ¶ 5).They believe reading cognition was always "fluid, artful, nodal, and so on" (McHoul & Roe, 1996, Celebrating Hypertext section, ¶ 8) and hypertext reading is still reading. It is just a different mode of delivering reading that may facilitate some aspects of reading.
Nonetheless, online reading of non-fiction poses challenges that are not faced in linear printed text. Keep, McLaughlin and Parmar (1993 -2000), Toffer (2000) and Morrison (2001) describe the main concerns with reading in a hypertext environment:
Context clues help provide cohesion in linear text (Keep, McLaughlin & Parmar (1993 -2000). The printed text uses context clues in sentences, paragraphs, chapters and the entire book to help readers follow the thesis or the story. Hypertext uses paths, or sequences of links or nodes to help provide continuity. Increased cognitive load
Reading on the Screen
"There are many ways that hypertext systems can be designed, and there is good reason to believe that a large number of those do not produce successful learning environments" (Spiro, Feltovich, Jacobson, & Coulson, 1991). The design of a hypertext learning environment affects the ability to learn and the type of learning that occurs in that environment (Puntambekar, n.d.). Just as some types of printed texts are better for some types of learning tasks than others, Puntambekar (n.d.) has pointed out that some types of hypertext environments are better suited to some learning tasks than others. Many factors should be taken into consideration in order to design a hypertext environment that facilitates learning.
Gleaves (1998) argues that
the strategies and techniques that people use to learn from books can improve
the effectiveness of learning with hypertext, and describes eight diffferent
principles that are used in linear text that can improve learning in an
hypertext environment.
Gleaves (1998) used these
characteristics of printed linear text to develop the following principles
of design for hypertext.
Designers of hypertext learning environments have used different learning theories to improve the effectiveness of these environemnts. The theory of situated cognition (Brown, Collins, & Duguid, 1989) can be helpful when applied to designing hypertext environments for successful learning experiemces. Situated cognition theorists regard knowledge not as just inside the person, but rather as a intertwining of the person and the environment in which the person works. Just as some types of printed texts are better for some types of learning tasks than others, Puntambekar (n.d.) has pointed out that some types of hypertext environments are better suited to some learning tasks than others. Cognitive apprenticeship methods, similar to those used in craft apprenticeship, can be used to support students learning . Teachers and classmates support student learning with authentic tasks by modelling, by providing support with scaffolding, and gradually withdrawing support when learners have mastered skills. "Cognitive apprenticeship supports learning in a domain by enabling students to acquire,develop, and use cognitive tools in authentic domain activity" (Brown, Collins, & Duguid, 1989) Spiro, Feltovich, Jacobson, and Coulson (1991) use the term cognitive flexibilityto describe the types of learning that occurs in an ill-structured domains. They believe that a hypertext environment provides a flexible learning environment for advanced learning. The authors make the distinction between intoductory learning, involving the understanding of basic concepts and facts and advanced learning, which requires mastery and the transfer of knowledge. Hypertext permits the same knowledge to be presented and learned in a variety of different ways for a variety of different purposes. Hypertext permits this cognitive flexibility. |
