摘要：
The growing wealth of information resources for education has brought unprecedented challenge. The question that how can we quickly and efficiently acquire the knowledge in learning has become a great concern to people. Text clustering is an automatic technology to summarize and classified text information, which will help people search the appropriate answer in the ocean of information. Text Clustering technology research in China is very hot now in the field of data mining, the application of text clustering in education is still in its infancy though it's valuable to using the text clustering technology in education. This paper discusses the concept As well as the lifecycle of text clustering and analyzes the current applications of text clustering in education, point out the advantages of Cluster retrieval of educational resources.

摘要：
The Sakai Community develops and distributes the open-source Sakai CLE, an enterprise-ready collaboration and courseware management platform that provides users with a suite of learning, portfolio, library and project tools. As an open source course management system, because of his open-source, as well as a powerful teaching function, sakai has received the great success at the global level, and its applications has also been in full carried out in domestic. In the sakai platform, the core is its permission management module, so if we want to have a comprehensive understanding of the operation and do some second developments about the sakai, let it apply in the teaching, we need to do some in-depth research about the permission management of the sakai. First of all, this article briefly introduced sakai and sakai application status at home and abroad, and it analyzed the sakai permission management from the types of user accounts and roles respectively, then it further studied the relationship among the sites, roles, users, and permissions, and lastly it given practical examples, and described how to write the permission in the development process.
摘要：
When the traditional text classification technologies classify academic dissertations, the dimension of extracted feature terms is high, and they can't represent the theme of thesis. it makes the efficiency is very low and the accuracy rate is not high. The topic words are small in quantity and can reflect the theme of thesis well. Accordingly, the paper proposes to extract the topic words with topic word list and uses topic words as feature terms. Then using the Bayesian classification method classifies vast texts. The experiments show that the Bayesian classification method using topic words as feature terms can greatly reduce the dimension and improve the efficiency of classification, when the dimension of feature terms is equivalent, the accuracy of Bayesian classification method using topic words as feature terms is also higher than the traditional Bayesian text classification methods.

摘要：
For students, classroom teaching is the process of learning knowledge from teachers. The efficiency of the teaching and learning process is affected by the choice of a teaching tool and the creation of classroom environment to a large extent. In this paper, the design and development of a new teaching system - soft whiteboard system is introduced in details, which provide more support for the teachers to create a positive and interactive classroom environment, thus to improve the teaching and learning efficiency.

摘要：
The amount of digitally available information is growing at an exponential rate. Educational resource systems are in widespread use and knowledge develops and spreads rapidly in quality, quantity, profundity and extension. This paper describes a new model of knowledge element to organize knowledge and to share the educational resource, and presents the framework of a knowledge abstract and fusion system based on it.

摘要：
Design and application of learning activity is an important content in e-learning. The paper firstly analyzes the state of art in designing learning activities, including Simple Sequence specification, Educational Markup Language, Learning Design theory and so on. In aspect of the compounding application between learning activities and learning resources, the paper discusses the basic designing strategy of the learning activities, and builds up the model to integrate learning resources and learning tools into learning activities. Based on the related learning theory, a case is discussed to design learning activities for a lesson. According to a true lesson using LAMS system, it analyzes the applied strategy and outcomes of the learning activities design. By the experiment, the results show that the integration of learning activities and learning resources can promote learning performance.
摘要：
Learner characteristics will determine the way they respond to both formal and informal learning environments. This paper explored learners' characteristics in distance learning, analyzed what should be improved in existing characteristics models, and then proposed a characteristics model of distance learners. According to this model, the characteristics of distance learners are divided into four features: demographic feature, environment feature, psychological feature and strategy feature. The research carried out with analysis on distance learners in China. The purpose of the research was to improve the educational experience of students studying distance learning courses.

摘要：
The educational information resource management system, which is based on SOA, achieves the goal of "change as need" for the system, ensures rapid update of the businesses and functions, improves the services of reuse, shortens the system development cycle, and cuts down the developed costs. This paper firstly analyzed the current educational resources management system, and found the existing problems, so it is suggested to developed resource management system based on the SOA, and it also demonstrates the advantages of the SOA-based resource management system. Then the paper introduces detailedly the Overall design of the educational resource management system based on the SOA, the system functions, and the system business process, and this paper also focuses on the implementation of the services related to the system, services Registration, discovery and call and the key technology of the services combination and flow arrangement.

摘要：
Although the Digital Rights Management of Education Resources (ERDRM) has developed greatly these years, there are still many problems, such as the conflict of the rights-protected and the resources-shared, especially under the network environment. And by now there is still no good method to solve the problem. So in this thesis, we design a new system model, and introduce the performing flow of the system. With the system, the education resource can be used freely and not be modified arbitrary in the network environment. The system is based on the technology of the core embedded tamper-resistant and the digital watermark, which both play an important part in the information safety.

摘要：
By means of curriculum resources reuse and sharing mechanism, SCORM can shorten the time of resources development, lessen costs and implement free circulation of learning content among hetero-platforms. However, excessive curriculum resources for reuse cause the problems of synchronous updating and low efficiency in learning resource utilization. In this paper, we propose a web services enhanced dynamic curriculum resources sharing model (DCRSM-WS) based on SCORM. Our method packages the SCORM based curriculum materials resources as web services, enables the requesters to dynamically connect to digital curriculum without replication and reduces the cost of curriculum construction.
摘要：
Organizations and communities are held together by knowledge flow networks whether people are aware of them or not. Knowledge flows influence the evolution of culture and language, promote international collaboration, and hasten the development of science. In this paper, we propose a Petri net based model of knowledge flow for more effective and efficient knowledge management, knowledge flow management, and knowledge flow network planning. We describe a research approach and modeling environment that enables the knowledge flows to be formalized through computational models. The model enables users to study knowledge flow in a visualized network and to develop strategies for adapting networks to changing conditions. The basic idea is to adapt and control logistical processes for knowledge flow within teams, organizations, and communities.
