Web teaching as a design consideration for the adaptive presentation of textual information
The understanding and the successfully acquisition of textual information seems to be highly dependent on the presentation sequence employed. System control and learner control can be optimally combined if there is a conceptual graph which represents the structural relations between the concepts in the text. Primarily based on the notions of Web Teaching (Norman, 1973), one can design an adaptive presentation mechanism. One algorithm for the computation of the centrality index of concepts in a network will be proposed. Consultancy of reader ratings based on prior knowledge seems to be necessary in order to match prior and new information.
