【摘要】：信息时代,教育信息资源的海量化与学习者快速获取满足自己个性化学习需求的教育信息资源之间的矛盾日益凸显出来。首先,学习者需要花费大量的时间、精力检索和鉴别资源,这大大加重了学习者的学习负担,致使无处不在的学习演变成无处不在的搜索。其次,信息素养的不同,导致不同学习者个体所搜集到的教育信息资源优劣程度不同,信息素养较高的学习者可以获取优质的资源,而信息素养较低的学习者找到适合自己的资源则比较困难,这逐渐加剧“优者更优,贫者更贫”。再次,普适性资源难以满足所有学习者的个性化学习需求,非主流的优质资源往往因主流资源的盛行而被永久性埋没,造成资源的严重浪费。最后,千篇一律的学习路径和学习系统容易忽视学习者的认知规律,引起学习者的认知过载和学习孤独,对学习者造成不容忽视的影响。作为缓解信息时代下“信息迷航”的有效手段,教育信息资源主动推送服务已经成为众多学者和专家的研究对象,但是研究成果及其应用效果并不理想。本文通过文献研究和内容分析法,比较现有的教育信息资源主动推送服务模型,从客观的角度总结其存在的不足,从而扬长避短,构建教育信息资源主动推送服务匹配模型。通过分析学习者与教育信息资源的属性特征和关联关系,确定该模型中的影响因素及其内在的匹配关系,设计基于该匹配关系的教育信息资源主动推送服务模型,并从学习者模块、教育信息资源模块、学习者与教育信息资源之间的匹配关系以及主动推送服务的实现机制等方面来阐释教育信息资源的主动推送服务。最后,设计、开发基于该匹配模型的模拟系统,对教育信息资源主动推送服务匹配模型的可行性进行验证。在此过程中着重设计教育信息资源、学习者的特征信息,设定其内在的匹配关系,并根据该匹配关系实现教育信息资源的主动推送服务。最终通过模拟实验来分析、检验教育信息资源主动推送服务匹配模型的可行性。
[Abstract]:In the information age, the contradiction between the quantification of educational information resources and the rapid acquisition by learners of educational information resources that meet their individual learning needs has become increasingly prominent.First of all, learners need to spend a lot of time, energy retrieval and identification of resources, which greatly increased the burden of learning, resulting in ubiquitous learning into ubiquitous search.Secondly, the difference of information literacy leads to different educational information resources collected by different learners. Learners with higher information literacy can obtain high quality resources.However, it is more difficult for learners with low information literacy to find suitable resources, which gradually intensifies the "better of the better and the poorer of the poor".Thirdly, universal resources are difficult to meet the individual learning needs of all learners. Non-mainstream high-quality resources are often permanently buried because of the prevalence of mainstream resources, resulting in a serious waste of resources.Finally, the same learning path and learning system tend to ignore the cognitive rules of learners, causing cognitive overload and learning loneliness, which can not be ignored.As an effective means to alleviate the "information confusion" in the information age, the active push service of educational information resources has become the research object of many scholars and experts, but the research results and its application effect are not ideal.Through literature research and content analysis, this paper compares the existing active push service model of educational information resources, summarizes its shortcomings from an objective point of view, and builds a matching model of active push service of educational information resources.Based on the analysis of the attribute characteristics and the relationship between learners and educational information resources, the influencing factors and their internal matching relationships in the model are determined, and an active push service model of educational information resources based on the matching relationship is designed.From the aspects of learner module, educational information resource module, the matching relationship between learner and educational information resource and the realization mechanism of active push service, this paper explains the active push service of educational information resource.Finally, a simulation system based on the matching model is designed and developed to verify the feasibility of the model.In this process, the educational information resources and learners' characteristic information are designed, and their internal matching relationship is set up. According to the matching relationship, the active push service of educational information resources is realized.Finally, the feasibility of active push service matching model of educational information resources is tested by simulation experiment.
