With the rapid development of informational technology, virtual community has played an important role in the progress of informational education. But on whatpsilas virtual learning community, there are many viewpoints. Someone thinks itpsilas a learning environment; someone regards it as a learning tool and so on. Based on the research existed, this article restudies the virtual learning community...
It is asserted that problem solving is the sole legal educational goal. But problem solving relies on appropriate scaffoldings to successfully implement. One approach that seems much promise of supporting it is to construct problem-based learning environments (PBLEs). PBLEs have tremendous potential for problem-based learning, but carry design challenges and concerns with them too. This paper will...
The paper presents a system that using multi-agent technology to organize and reorganize supportive communities based on learners. Through effective award and exchange algorithms, learners with similar interests and experiences form a community to support each otherspsila learning.
With the development of information technology (such as computer network, etc.) and the renovation of education ideology, the network course already became an important constituent of the distance learning resources, also the network collaborative learning has become a hot research area in contemporary education. But the study efficiency is to be low in network cooperates on the present, the learner...
The topology of a network has close connections with the performance of routing algorithms based on it. In this paper, we propose an evolving model named SNCS to characterize both scale-free property and community property of many communication networks simultaneously. Then, we build a traffic model based on SNCS and use a simple routing strategy to investigate the impact of community structure on...
In this paper, a new local algorithm of community detection which requires mostly local information while detecting communities in networks is proposed. The algorithm is available in both unweighted and weighted networks. It starts from vertices with low intensity and extracts communities from networks. Three real-world networks are used to test the performance of algorithm proposed, the experimental...
This paper explored the demand motivation of virtual money which exists in an online game or virtual community. As the virtual money can only be bought from but not sold to the game operators currently in China, the motivation for owning virtual money in China is just limited to online payment, no speculation motivation as in foreign online games which have a totally different exchange mechanism with...
Researches on information communication and technology (ICT) teacherspsila training are focused on training courses and train models in recent years, thus by lacking to probe into theories which support training, such as learning theories, activity theory and knowledge management theory. This paper briefly describes those theories above, and explores ICT teacherspsila training from multiple theoretical...
In accordance with the principles of system analysis, the paper put forward the ideas of "from subject determination to structure decomposition" to construct the evaluation index system for community informatization construction. And, referring to the existing evaluation index system for community construction, the paper used analytic hierarchy process (AHP) to analyze and build an evaluation...
The online virtual money is issued by private-owned game operator, with the goal of profit maximization, which makes a significant difference in the money issuance mechanism between virtual money and real money. This paper focused on studying whether the operator, driven by profit maximization, would over-supply the virtual money and cause inflation in virtual world. Two virtual money supply models...
The synergetic theory, an important systems science has already been applied widely in each domain, but it is used little in the sports curriculum reform. This research is about the application of synergetic theory together with information technology and computer technology in sports curriculum. Culture is the important foreword parameter to conduct the deep research which to explore one kind of...
A learning community is a group of people who share common values and beliefs, are actively engaged in learning together from each other. In order to improve the teaching and learning quality of our college, teachers and students were assigned into various learning communities. An information system is needed to provide good supports for learning communities. There are many kinds of tools which can...
Introducing e-learning can obviously improve the learning efficiency. How to introduce profit contents to users is the key issue. An available way is to introduce the same contents to the users with similar interest and study ability. Community detection can divide users into several subgroups with similar interest and study ability. An e-learning system can determine the introducing contents for...
