【摘要】 随着信息时代的不断发展,网络教学的不断深入,网络课程教学资源将为普通教育、高等教育、成人教育乃至终生教育提供重要的教育保障。面对网上学习资源的不断丰富,学习者以及学习需求的多样化趋势,如何有效组织网上的学习资源,实现网络教学资源的共享与重用,来灵活构建个性化的学习内容是一个非常热门的研究课题。 本文把面向对象的构件思想与相关的教育教学理论相结合,将构件技术运用到网络教学,提出了教学构件的思想,希望能为教育领域发挥软件构件的效用。主要设计了两大类构件模型:内容教学构件模型和编列策略构件模型。为了解决资源和知识不同层面构件共享重用以及重组,将内容构件分为资源构件和知识构件,根据资源的类型和知识的特性对各类资源构件和知识构件的描述模型进行了详细地设计;编列构件是对各种编列策略或编列规则的构件化描述,相同的内容构件根据编列构件的不同描述组合成不同的学习内容,满足个性化学习的需要,从而设计了相应的重组算法,并把其运用到网络课程实例中,实现内容构件的灵活重组:静态重组和动态重组。最后对内容重组中的构件检索和匹配关键技术进行了较深入的研究,包括检索匹配的模型设计和算法设计,并对内容构件进行了模糊匹配综合评价。 本文的研究和设计为开发个性化智能网络学习原型系统提供了理论依据和设计方法,其教学构件的部分设计思想在本课题组开发的网络课程知识服务平台中得以实现。更多还原

【Abstract】 With the development of information and e-learning, the e-learning resource plays an important role in general education, higher education, adult education and even the lifetime education. Facing the abundant e-learning resource and the multiple need of learner and learning, how to effectively organize the e-learning resource, how to realize the share and reuse of the e-learning resource and how to build the neatly personal learning content become a hot topic.This paper combines the object-oriented component ideas with relevant education teaching theories and applies component technology to e-learning. The instruction component is put forward and will be an effective component in education field. It designs two-kind models: the content component model and the sequencing strategy component model. In order to share, reuse and recombine resources and different component levels, the content component is divided into resource and knowledge component. These components are detailedly designed on the basis of resource style and knowledge characteristic. Sequencing component describes various sequencing strategies and rules by which the components of the same content are combined into different learning content, thus can satisfy the personal learning requirement. To achieve the flexible static and dynamic recombining, recombine algorithm is proposed and applied to the instance of the e-learning course. Finally, the further research of this paper is on the component searching and the key component matching technology, including the model and algorithm design of matching and searching. The synthesis evaluation of fuzzy matching of content component is proposed.This paper provides theories and design methods for developing the personal and intelligent e-learning prototype system. Part of the component design ideas are realized in the e-learning course knowledge services platform which is designed by our research group更多还原
