Abstract

The long-range goal of the research reported here is to study the role of hypertext-based external representations in augmenting performance on a cognitively complex task, in particular, on a synthesis writing task. The production of a written synthesis is a challenging task that requires managing large amounts of information over an extended period of time. Thus, synthesis writing is a task that is well-suited for testing the potential of hypertext technologies to support work on complex tasks.From a case study of experts and novices, we have developed a theory of the cognitive processes involved in producing a written synthesis. We have also developed a preliminary theory of the role of external representations in the writing process. We have drawn upon these two theories to design several hypertext-based external representations that we believe will augment writers' performance on a written synthesis task. The hypertext-based applications include a general graph object and a table object; these objects form the foundation for a set of specialized tools to support synthesis writing, namely, a summary graph, synthesis grid and synthesis tree.
