【摘要】 与传统信息载体相比,网络信息载体具有可复用、动态交互的本质特征,使得资源的使用者之间,以及资源的使用者与资源之间能够形成跨越时空的立体化互动。基于该现状,以长尾理论、里德定理为依据,以生态资源观和用户信息行为的前期研究的基础,构建了网络环境下教育信息资源动态发展利用模型。采用跟踪观察法,通过对网络资源的跟帖、留言的分析,统计网络教育信息资源总量的变化,得出网络教育信息资源量的增加呈现先慢后快再慢的规律;采用内容分析法,分析了网络教育信息资源质的增加,得出资源内容在广度上得到扩充,在深度上得到加深的结论;以量的研究为基础,分析了单位时间内量的增加,得出网络环境下教育信息资源动态发展利用过程具有生命周期的特点。更多还原

【Abstract】 In contrast with traditional information vehicles,web possesses the characteristics of reusability and dynamic interactivity,which makes users communicate and interact with others or resources without any time and space limit.On the basis of the web’s characteristics,under the guidance of the long tail.and Reed’s law,and combining with early studies on ecological resources view and users’information behavior.This study constructed a model of the dynamic development and usage of education information resources in network environment;This study adopted following observation method,analysized follow-up comments,counted the change of education information resources in quantity and came to that the quantity of education information resoutces was on the increase and the increased speed was firstly slow,secondly quick and then slow ;This study adopted content analysis method,analysized the change of education information resources in qulity,and came to that education information resources could be complemented and deepened;At last,based on the change in quantity,this study summed up the change of education information resources in unit time,and concluded the lifecycle of education information resources in networked environment.更多还原
