The Design And Development Of Based Web Collaborative Learning Platform

The rapid development in science technology characterized with multimedia technology and network technology greatly influenced modern society and then results in the fundamental change in terms of ways of living and production mode, enabling the economy undergo the fundamental transition. Thus people can just adapt themselves to the change through life education. As an easy access to receive life education, in comparison with traditional education, remote education unrestricted by time and space can offer all the learners an equal opportunity regardless of their individual difference. In view of teaching method, changing the passive study under traditional mode into active knowledge-seek, remote education can motivate the learners to fully employ their learning potential. On the other hand, it also can improve the traditional method characterized with uniformity by designing the course based on individual's intelligence and self-taught capability.The thesis provides a new mode of remote education which is Web CL (Web based collaborative learning). Collaborative Learning (CL) is what that's all about - learners working together as a group to accomplish shared goals and maximize the learning of each individual by an incentive scheme. There are five essential components that must be present for small-group learning to be truly collaborative. They are (l)clear, positive interdependence among students, (2)regular group self-evaluation, (3)interpersonal behaviors that promote each member's learning and success, (4)individual accountability and personal responsibility, and (5)frequent use of appropriate interpersonal and small group social skills. Web Based Collaborative Learning is the CL that supported with Web Technology. Based on the experiment in <>, the author combines the technology of multimedia, network and database to project the research of Web CL system. With the help of the system, the learners are supposed to connect themselves to the homepage of the system through Internet or School's Intranet for course-learning. In this way, they could either discuss the problem with their classmates or ask one-to-one instruction form on line. More, they even can connect themselves to a platform forexperiment so as to cooperate with their classmates to co-accomplish the assignment. Also the system invents a remote system for exam, which can not only test learners on lien, but also keep record of the course to obtain solution so as to facilitate the evaluation of learners achievement in course learning. And it opens up the access for developing three-dimensional white board by which teachers and learners can design their three-dimensional graph and revolve, move.The thesis introduces the basis, the design idea and the process of concretely realization in great detail. At first, the first two chapters introduce the situation of collaborative learning system in the internal and external, the whole survey, the design environment and base of thesis. Then the following chapters introduce the design of system, the technology of realizing this system, the main function of the system and the achievement process of the system in detail. The order of the chapters is separated by the technology of what the system uses. The main three technologies are network database, multimedia and Java. The last chapter sums up the whole system and points to the places what the system should still be completed and corrected.
