Weeber, Marc; Klein, Henny; de Jong-van den Berg, Lolkje T. W.; Vos, Rein – Journal of the American Society for Information Science and Technology, 2001
Proposes a two-step model of discovery in which new scientific hypotheses can be generated and subsequently tested. Applying advanced natural language processing techniques to find biomedical concepts in text, the model is implemented in a versatile interactive discovery support tool. This tool is used to successfully simulate Don R. Swanson's…

Moens, Marie-Francine; Dumortier, Jos – Journal of Documentation, 2000
Describes the design and implementation of a system for creating highlight abstracts to select relevant online magazine articles. Explains parsing texts based on text grammar and extracting sentences and statements that are relevant for inclusion in the abstract; and discusses knowledge representation and the importance of discourse structures in…

Kintsch, Eileen – Topics in Language Disorders, 2005
This article begins with a brief overview of the psychological research on the pedagogical efficacy of questions and describes how recent research has led to a reevaluation of the role of questions within the framework of a theoretical model of discourse comprehension processes and knowledge representation. A computer-based tutor for reading…

Martin, Randi C.; He, Tao – Brain and Language, 2004
Previous studies have shown that an aphasic patient (AB) with a semantic short-term memory deficit (STM) had difficulties comprehending and producing sentences with structures that demanded the simultaneous retention of several individual word meanings (Martin & Freedman, 2001a, 2001b; Martin & Romani, 1994; Martin, Shelton, & Yaffee, 1994). The…

Suthers, Daniel D.; Hundhausen, Christopher D.; Girardeau, Laura E. – Computers & Education, 2003
This paper reports an empirical study comparing the role of discourse and knowledge representations (graphical evidence mapping) in face-to-face versus synchronous online collaborative learning. Prior work in face-to-face collaborative learning situations has shown that the features of representational notations can influence the focus of…

Chen, Pearl; McGrath, Diane – Journal of Educational Multimedia and Hypermedia, 2003
This study documented the processes of knowledge construction and knowledge representation in high school students' hypermedia design projects. Analysis of knowledge construction in linking and structural building yielded distinct types and subtypes of hypermedia documents, which were characterized by four features of knowledge representation: (a)…

Marshall, Byron B.; Chen, Hsinchun; Shen, Rao; Fox, Edward A. – Journal on Educational Resources in Computing, 2006
The GetSmart system was built to support theoretically sound learning processes in a digital library environment by integrating course management, digital library, and concept mapping components to support a constructivist, six-step, information search process. In the fall of 2002 more than 100 students created 1400 concept maps as part of…

Black, John B.; And Others – 1995
Task analyses have traditionally been framed in terms of overt behaviors performed in accomplishing tasks and goals. Pioneering work at the Learning Research and Development Center looked at what contribution a cognitive analysis might make to current task analysis procedures, since traditional task analysis methods neither elicit nor capture…

Flanagan, Robin C.; Black, John B. – 1997
Computer-based learning environments are proliferating in an effort to make more resources available to more students in more timely and individualized ways without overtaxing diminishing budgets. Many computer-based learning environments are designed to facilitate meaningful interaction, however, interactivity is only one of the factors that…

Ruiz-Primo, Maria Araceli; Schultz, Susan E.; Li, Min; Shavelson, Richard J. – 1998
A concept map is a graph in which the nodes represent concepts, the lines between the nodes represent relations, and the labels on the lines represent the nature of the relations. Concept maps have been used to assess students' knowledge structures, especially in science education. Two concept mapping techniques, constructing a map and filling in…

Wang, HsingChi A.; Marsh, David D. – 1998
The purpose of this study was to investigate teachers' perceptions of the instructional role of the history of science and their actual practices of teaching science from an historical point of view. Specifically, this study is intended to answer the following research questions: to what extent do science teachers agree with the proposed…
