They are all very useful for students’ study. Personalized teaching systems are gradually However, in facing of the rapid development of introduced into the teaching field along with the information society, how to extract, publish, and share development of information technology and many fruits efficiently from the massive resources, arouse the are achieved. But people must re-examine the teaching initiative of students, and how to expand and extend and learning based on information technology with the the learning content based on the existed teaching arrival of Web2.0 era. There is no doubt that the system are issues that need to be re-examined. development and utilization of Web2.0's ideas and Fortunately, it may be a good way to solve the technologies have been bringing new vitality to problems as the Web2.0’s arrival. So, the construction teaching and learning. How to make better and more of personalized teaching system based on Web2.0 is a efficient use of the technologies and ideas in teaching valuable topic that worthy researching and developing. and learning should be paid more attention. So, in order to facilitate teaching and learning efficiently, personalized teaching system need to be fully 2. Value of Web2.0 in facilitating researched. This paper is to analysis the technologies personalized teaching and learning and ideas of Web2.0 and their value to the personalized teaching and learning, construct the 2.1. What is the Web2.0 personalized teaching system framework based on Web2.0 and then analysis and design its personalized We still can not give a clear, convincing definition modules. The purpose is to combine Web2.0's to Web2.0. Blogger Don, in" Interpretation of the technologies and ideas with teaching system design for concept of Web2.0" ,said that "Web2.0 is a new model teaching and learning. of internet represented by Flickr, Craigslist, Linkedin, Tribes,Ryze,Friendster,Del.icio.us,43Things.com, 1. Introduction including Blog, TAG, SNS, RSS, Wiki and other social software as the core, based on six-times division, The purpose of design and development of teaching XML, Ajax, and other new theories . "[1] We can see system is to facilitate the students' learning. Rich that Web2.0 is not a single technology, but an resources and many learning models are gradually integration of a variety of technologies and theories. So utilized by students, as the changing from the CAI Web2.0 can be used as an idea in most cases. courseware at first to the network courses and on-line Originating from Web1.0, Web2.0 fully presents its learning nowadays. However, it is a problem that how characteristics of non-centralization, personalization as to choose their own facing so many resources and well as the self-organization of information. Perhaps it models deserves carefully considering. In the past, is because of these, Web1.0's ideas and technologies especially in times of Web1.0, most concerns were are thrown far from behind of the times. Web2.0's paid on rich resources, direct presentation and passive social software, such as Blog, Wiki, RSS, SNS, IM and application. The research, design and development of P2P, enables the releasing, obtaining, updating, personalized teaching system based on Agent, B/S deleting, and utilization of information more barrier- many layer structure, web, web data mining, free and convenient. information theory etc. have many innovations in 978-0-7695-3311-7/08 $25.00 © 2008 IEEE 524 DOI 10.1109/ISCID.2008.165

  3. 3. 3.1.1. Exchange and cooperation between Learners. question and answer online, teaching forum, an In personalized teaching system based on Web2.0, they interactive on demand; public service module includes are in equal status between students and teachers. They resource management, authority management, search are connected peer-to-peer. Students will join together help, and so on. With the design and utilization of by Social Network Software to expand their relations these modules, on the one hand learning will be more with others and powerful learning communities can be convenient and instant; the real teaching is reproduced formed. In the community learners all can achieve from invisible system, too; on the other hand the progress by communicating with each other barrier- system can be more optimization, learning and freely, establishing partnership, and helping each other. teaching will be in order, too. At the same time, according to the theory of six-time Social learning software: The powerful social division, students can continue to communicate with software of Web2.0 is used in personalized teaching more learners, so students in the communities will be system. The social software of Web2.0 provides more more and more. So more valuable resources will be convenient ways of information exchange in teaching continue to added to the teaching system as the and learning for teachers and students. Students can students increase because students are also the creators establish Blog and Wiki on a subject by individuals or of learning content and resources. Teaching system and groups. More students who are interested in it can join resources are no longer considered as the center by in and make exchange, evaluation and discussion with students. In contrast, learners become the center in the help of Tag, RSS, SNS .Internet exchange platform teaching system and learning process. So, it is a typical and virtual teaching and research platform can be learner-centered teaching and learning system. constructed naturally ,which students can use for self- study, learning based on research and collaborative 3.1.2. Sharing of resources among learning sites. learning.[4] The communicating tools of Instant Learning content and resources are no longer from one Messaging enable learners to feel the true reality of or some isolate sites in the personalized teaching learning from each other and sharing the feeling face- system based on Web2.0, but from a series of to-face with teachers and other students. connected sites. Resources can be shared and polymerized through RSS between the site and site, so 3.1.4. The learning process of students. Students can the resources and content can also be expanded. When push and pull learning content and resources to and the learners want to get access to certain types of from personalized teaching system based on Web2.0 learning content and resources, they can be gathered on through friendly easy-to-use personalized navigation the site from others automatically. At the same time, system .At the same time students can make full use of the content and resources of polymerization will be the social software for learning and push excellent stored, so that students can utilize them more learning content and resources to the learning site. conveniently. As can be seen, the more sites are Also, students can get access to the latest information connected, the richer resources students can get access and resources according to their needs through RSS to. readers. They can read learning content and information even not accessing the internet. Because 3.1.3.

[6] Students can use Blog and other social software at any time to demonstrate their feelings, learning fruits, excellent learning content and resources. Students are not only the learners but more importantly are also the creators of the resources. They are the real masters of Figure2.Model of RSS in personalized teaching network. They can obtain and release the personalized system learning content and resources according to their interests and needs. In this case, the initiative of One of the most popular using of XML (The learners must be fully aroused. Extensible Markup Language) is RSS. Generally Students participate in the learning will have mutual speaking, it can be regarded as an extensive model of exchange and collaboration by SNS. They are no resource sharing. Students can take full advantage of longer the competitors independently. They can be learning resources through resource sharing and organized in different approaches and framework gathering modules in personalized teaching system. At between students, students and content, students and first, a RSS Feed is released by student, and then the activities, as well as students, content and activities. customized information contained in the RSS Feed can These also can be combined into a collective body. It is be called by the site or directly called by other sites. It the so-called self - organization. is easy for the data and information to be utilized in The interactive is much easier because of two-way other terminals and servers because they are in dynamic real-time information transmission (or IM). formation of standard XML. At the same time, RSS Learners can get help and feedback of the teachers and Feed can also be called each other among the sites. So, other students instantly and they can also give response learning resources and the latest information can be and help to others. The process can be demonstrated as obtained automatically. This is the so-called Web figure 3. Alliance (or the Alliance of RSS).In most cases, because different RSS channels are dynamically tied as the format of OPML(Outline Processor Markup Language), categorized and filtered information and resources can be delivered to the students real-timely, quickly and efficiently. Personalized selection of information is realized. So the original isolate islands of information converge on an interactive group. In this group information and resources can be shared conveniently. [5] Students can also make configuration of the relevant parameters according to their needs in the RSS Figure 3.The model of students’ learning process Readers, such as: initial state of the system, the way of information browse, the selection of channel update, The initiative, participation and interest of learners the settings of network links, and so on. arouse because of User-driven rather than editor-driven teaching system based on Web2.0. The efficiency is 3.2.2. Participation and interactive of learners in higher because of the interaction. personalized teaching system based on Web2.0. It is a problem that how to arouse the enthusiasm of 3.2.3. The scalability of platform and seamless students and improve the efficiency of learning must connection for personalized teaching system based be considered by all teaching systems. How to achieve on Web2.0. The platform scalability and seamless is the goal? A number of attempts are carried out in many another feature of personalized teaching system based personalized teaching systems, but few satisfactory on Web2.0 due to the application of Ajax. Learning results are made. The ideas of non-centralization, platform can be customized because the system can be personalization, autonomy, grass-roots, and the social established according to the learning groups, activities, software of Blog, Wiki, Tag, IM are used in knowledge and learning process of students. personalized teaching system based on Web2.0, which Application platform can be updated and expanded makes students absorbed in learning system deeply. immediately according to the changing of students' Not the learning content and resources but the students groups and knowledge. At the same time, in the 527
