Abstract

As a growing learning technology, hypermedia needs to be examined in terms of the cognitive processes it encourages in users. Descusses the characteristics that circumscribe hypermedia. Presents 2 perspectives on learning from hypermedia: purpose of usage (culture, education, information) and usage context. Describes 4 cognitive processes involved in hypermedia usage: browsing, searching, integrating, and angling (establishing multiple perspectives). Discusses 2 cognitive pitfalls: hyperspace wandering and cohesion deficit

Abstract

Hypertext uses a browsing rather than a searching strategy. Hypertext systems have found applications in a number of areas. They give users choice of information but this can prove a drawback. Examnines the effectiveness of hypertext as a way of retrieving information and reviews conventional information retrieval techniques. Considers previous attempts at combining information retrieval and hypertext and outlines a prototype systems developed to generate guided tours for users to direct them through hypertext to information they have requested. Discusses how adding this kind of itelligent guidance to a hypertext system would affect its usability as an information system

Abstract

Criticizes the current processes of information management, with the objective of arriving at a new concept of the electronic document. Discusses problems of human language in the context of information management. Examines the problem of information from the point of view of the structure of knowledge, by analysing dysfunction in current processes of information management. Proposes a model of knowledge nearer to the human mind called 'document hypertext'. A combined interface of information management id also applicable in studies of hardware, graphic interfaces and metaphors of visualization of information. The current excessive fragmentation and artificial treatment of information structures could be avoided by simplifying of processes of information management and creating integral interfaces that bring information systems closer to the user

Abstract

Dieser Beitrag diskutiert die Frage, inwieweit Hypertext als informationsvermittelndes System dem menschlichen Wahrnehmungsapparat adäquat ist. Die Vorgehensweise ist vergleiched. Konventioneller linearer Text wird, allein aufgrund seines Erfolgs in der kulturellen Tradition, als adäquat vorausgesetzt. Anhand grundlegender Maximen der Interaktion werden Parallelen und Unterschiede zwischen Text und Hypertext aufgezeigt, und die Konsequenzen dieser Gegenüberstellung werden anhand eines konkreten Hypertextsystems dargestellt

Abstract

Proposes a theoretical framework for organizing information and activities in educational hypermedia systems. Focuses on the content that can be represented within a physical media, rather than the physical media itself. Proposes a theory of cognitive media types based on the inferential and learning processes of human users. Presents an implemented computer system, called AlgoNet, that supports hypermedia information access and constructive learning activities for self paced learning in computer and engineering disciplines

Abstract

Hypermedia information systems, because of their inherent qualities of nonlinearity and associative linking, offer the potential of facilitating enhanced knowledge representation and construction for users. These capabilities will be more fully realized if hypermedia information systems are developed and implemented based on constructivist learning theory. Examines the qualities of hypermedia systems that enable them to facilitate learning, discusses the background of current learning theories and provides a brief view of a possible hypermedia system based on constructivist learning principles that could be developed through the use of intellegent autonomous agents
