( 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(yīng)教育超媒體系統(tǒng)結(jié)構(gòu)的參考模型通過(guò)對(duì)已有的教育超媒體系統(tǒng)的結(jié)構(gòu)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(yīng)于自適應(yīng)教育超媒體的系統(tǒng)結(jié)構(gòu)參考模型,在建立系統(tǒng)結(jié)構(gòu)參考模型的基礎(chǔ)上進(jìn)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(gè)方面:多媒體計(jì)算機(jī)的交互性有利于激發(fā)學(xué)生的學(xué)習(xí)興趣和充分體現(xiàn)學(xué)生主體作用;多媒體計(jì)算機(jī)提供外部刺激的多樣性有利于知識(shí)的獲取與保持;多媒體系統(tǒng)的超文本特性可實(shí)現(xiàn)對(duì)教學(xué)信息最有效的組織與管理;計(jì)算機(jī)網(wǎng)絡(luò)特性有利于實(shí)現(xiàn)能培養(yǎng)合作精神并促進(jìn)高級(jí)認(rèn)知能力發(fā)展的協(xié)作式學(xué)習(xí);超文本特性與網(wǎng)絡(luò)特性的結(jié)合有利于實(shí)現(xiàn)能培養(yǎng)創(chuàng)新精神和促進(jìn)信息能力發(fā)展的探究性學(xué)習(xí)。
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(rèn)知超媒體信息空間的基礎(chǔ),從深層揭示導(dǎo)航支持與用戶認(rèn)知的復(fù)雜性及其內(nèi)在規(guī)律,分析探討超媒體系統(tǒng)智能導(dǎo)航的模型基礎(chǔ)(用戶模型與知識(shí)庫(kù))及可視化技術(shù),構(gòu)建了認(rèn)知參考模型、智能導(dǎo)航概念模型、智能導(dǎo)航框架結(jié)構(gòu)模型并運(yùn)用petri網(wǎng)技術(shù)模擬實(shí)現(xiàn)。
