Network Preparation Lessons System Based On Collaborative Editing

In contemporary China on the teaching quality and the foundation of the new curriculum reform is concerned, how to improve the quality of education and teaching has been attached great importance to the community. In the educational activities, the preparation is an important part of teaching activities, school-based teaching research is an important link, it is effectively to reach the important guarantee of the quality of teaching. With the continuous progress of education, the lessons from the form once the individual preparation changes to the collective network planning, advanced technology and the concept of more and more start into the teaching practice. In this paper, we study the network based on collaborative editing technology preparation system for teachers preparing lessons, to further improve the efficiency of the work of teachers, improve education information process.Based on the needs of teachers and lesson activities on the process of understanding, and from the point of view of the reality of the collaborative editing thought into the whole system, subdivided according to the preparation of the actual process for preparing the session management module, teaching document management module lesson plan collaborative editing modification module. Which focused on the design of collaborative editing module, from the cooperative awareness, version control and consistency algorithm maintenance specific aspects, to solve the lesson plan collaborative editing of a series such as concurrency conflict and perceived deficiencies, lesson plan version disorder problems. The really designed to achieve a multiplayer real-time online collaborative editing of professional teachers’ network preparation system.At last, the paper has preliminarily realized the a web-based collaborative online preparing lessons systems based on, from the point of view of implementation are respectively on the preparation process management module, teaching document management module and collaborative editing module detailed design and implementation issues for further discussion. In the specific implementation process, considering comprehensive factors decide the whole system using B / S mode, combining the JavaEE technology and B / S three layer structure model, including the use of front-end web technologies(HTML + CSS technology +JavaScript Technology) and back-end server(JavaWeb Technology) and database technology the basic realization of the end of one of the available web collaborative editing online preparing lessons systems, and through the authentication and data binding technology, improve system security and easy maintenance, the system interface is simple and focused.
