Design And Implementation Of A AJAX-Based Teaching Resources Platform

With the rapid development of Internet, the network technology has been greatly impacting the innovation of the education. However, B/S application program confined to HTML is not capable of displaying data with abundant effects as C/S does. As a result, it brings the bad users'experience and can hardly match the requirements from the teachers and the students, nor can it arouse students'interest in learning, with its poor encouraging role. Then the promotion and the encouragement can hardly be carried out in the teaching. The essential factors in developing a well-functioning teaching resources platform lie in such aspects as offering satisfactory users'experience, presenting integrated and abundant learning materials, promptly and effectively addressing the difficulties rising in students'learning, efficiently checking and correcting the assignments of students, enhancing the qualities and efficiencies of teaching as well as assessing, supervising and managing students'academic activities.According the requirement mentioned above, in this thesis, requirement analysis of the system has been carried out first, and the system has been divided into two parts: front part for the teachers and students and the back part for the teaching managers and the system managers. The concept of group has also been proposed, which means that the teachers can sorting the students and the resources into different groups with the corresponding properties, which facilitates the communications and discussions between the teachers and the students. Then the resources have been divided into the curriculum-resources and the group-resources according to the different curriculums and groups, and also into online and download resources. The entire design of the system has been implemented secondly, and the concrete design is following surrounding the assignment management and the relationship between the resources, the curriculums and the groups. Database design and page design have also been taken account and the system has been more completed and humanized via the realizations of the modules for the message, announcement, personal information management, curriculum information management.For the realization of the page, through analyzing the four key techniques to implement AJAX, the system has much better user experience by reducing waiting-time of the users'manipulation in terms of AJAX technique. Beside this, the system could be more friendly and easily used through good-operating design of the page. Moreover, for the realization of the operation, the system has also been humanized by means of introducing the concept of the group, setting up of the assignment-tree and resource-tree, optimizing the processes of the assignment submission and marking, defining various ways for the messages, and so on.
