The Research Of A Cooperative Preparing-lessons System Based On Internet

Arriving at the 21st Century, information technology has been widely developed. More and more teachers begin using Internet to serve their teaching. They search courseware and good instruction designers on Internet. But for so much information and no good methods and suitable software, the teachers have met many problems; they wasted too much time and energy on useless things. It has obstructed the applying of information technology. The reason is just that the teachers have no good tools and no good information environments to conveniently and comfortably use Internet in their teaching.So the thesis brings up a theory about a preparing-lessons system based on Internet. We hope it can collect useful information of teaching properly, thus teachers can easily get them. It also can arrange the advanced teaching ideas and experience of elite teachers so that all people can share them. We also hope it can give us a cooperative environments to make the teachers can work together, and give us a safe 'home' for us to work and to learn and to communicate safely.In this thesis we analyzed some advantages and shortages of various educational systems. And upon which it brought out a detailed requirement analyses (including the solution plan analyses,feasibility analyses and functional analyses, etc) and the framework of the system. At the same time, every module in the system is described including its functions, implement principles and code samples, etc, and lastly we worked out a demo for the educational system.
