Effects Of Knowledge Representation On Knowledge Acquisition And Problem Solving, Mohamed Khalifa, Kathy Ning Shen

University of Wollongong in Dubai - Papers

Abstract: The way knowledge is represented influences the effectiveness with which that knowledge can be shared and reconstructed. Of particular interest to this study is the hypertext knowledge representation. Based on the schema theory, we propose a model explaining the effect of the hypertext knowledge representation on the user’s problem solving performance. The sophistication of the knowledge structure that the user can construct from the hypertext knowledge representation is proposed as an intervening variable mediating the effect of hypertext on the problem solving performance. According to our model, the hypertext representation of the “collective schemata” of a group of experts …
