Study on bayesian networks technology in adaptive hypermedia system 貝葉斯網(wǎng)絡在自適應超媒體系統(tǒng)中應用研究
( 2 ) exp1oring and advancing the reference model of self - - adapting education hypermedia system construction through the ana1ysis for the exist construction and function of hypermedia system , point out the error of current education hypermedia . advance a system construction reference mode1 suiting for se1f - - adapting education hypermedia . make the ana1ysis based on the estab1 ishing system construction reference mode1 ( 2 )探索并提出自適應教育超媒體系統(tǒng)結構的參考模型通過對已有的教育超媒體系統(tǒng)的結構和功能的分析,指出目前教育超媒體所存在的弊病,提出一種適應于自適應教育超媒體的系統(tǒng)結構參考模型,在建立系統(tǒng)結構參考模型的基礎上進行分析。
The variety of simulates offered by hypermedia is good for achieving and keeping information . the hypertext of hypermedia system can validly orgnize and manage instructional information . network is favourable to collaborative study that can cultivate cooperative spirit and accelerate development of higher cognitive ability . the combination of hypertext and network is benificial for discovering study that can cultivate creating spirit and accelerate development of information ability . whatsmore , information technology offers better instructional environment and technology support for mathematics experiments 表現(xiàn)在如下五個方面:多媒體計算機的交互性有利于激發(fā)學生的學習興趣和充分體現(xiàn)學生主體作用;多媒體計算機提供外部刺激的多樣性有利于知識的獲取與保持;多媒體系統(tǒng)的超文本特性可實現(xiàn)對教學信息最有效的組織與管理;計算機網(wǎng)絡特性有利于實現(xiàn)能培養(yǎng)合作精神并促進高級認知能力發(fā)展的協(xié)作式學習;超文本特性與網(wǎng)絡特性的結合有利于實現(xiàn)能培養(yǎng)創(chuàng)新精神和促進信息能力發(fā)展的探究性學習。
It has the important actual meaning in the aspect of raising the use of the further management and service in information management domain . the dissertation stars with the structural property of hypermedia system , and has discussed the element and optimization schemes of hypermedia system structure , and has analyzed the cognization factors when user is browsing in hypermedia information space , and introduces the technical condition in the design of hypermedian 以空間隱喻作為用戶認知超媒體信息空間的基礎,從深層揭示導航支持與用戶認知的復雜性及其內在規(guī)律,分析探討超媒體系統(tǒng)智能導航的模型基礎(用戶模型與知識庫)及可視化技術,構建了認知參考模型、智能導航概念模型、智能導航框架結構模型并運用petri網(wǎng)技術模擬實現(xiàn)。
