Assistant Instructional System's Design And Implementation Based On Web

Along with the development of multimedia and network technology, web-based instruction has been developed and popularized rapidly. So, an important task which need to solve urgently is to construct a new mode of continuing education and studying for life, which is untraditional and not limited to the region and time construction advocates the teaching environment in which learners is the center, and they actively explore, find and construct the meaning from what they have learned. Such environment is just what the network can provide. The wide-range application of network-based class teaching system enables the learners to realize the "constructing study"Based on the comparison of those existing education systems and the analysis of their advantages and disadvantages, this paper puts forward the main function of multimedia platform. On the basis of some characteristics and requests about assistant education system, the thesis produces the whole plan and design by some technologies about Information System ways and System Modeling technology. It introduces the programming model and system structure. At the same time, it looks into several technology's problems encountered during the development (buffer storage, hard coding of SQL program statement, data query technology and multiple-order security management). The system has been applied in the lab instruction and got optimistic resultsThis system adopts ASP(Active Server Pages) Work out the procedure , regard Access database as the procedure database in high-level languages. All functions were realized by forms of network based on bower/server (Bower/Server), namely all functions were operated long-rangly , and can realize the multi-user operates.
