Abstract


With the computer technology and network technology, the rapid development and popularization of people’s lives and learning has undergone tremendous changes, these technologies have affected all areas of society, but has incomparable advantages of traditional education, distance education is its technological development Results. The development of modern distance education system for lack of traditional education model has played a huge role in the improvement, it greatly limits to meet the needs of people for education, providing a wealth of teaching resources for learners to create a convenient, free learning platform.This article describes the distance education system, ASP.NET-based three-tier architecture, ASP.NET its excellent cross-platform and maneuverability, more and more programming and technical personnel have been used as development platform. In this paper, the background of distance education and development trends as well as design theory and techniques used in a brief introduction, followed by pairs of distance education functions of the various sub-system analysis and outline the design, focusing on details of the Distance Education System examination subsystem, and its detail design, and gives a specific implementation plan.Automatic composition test paper algorithm in examination subsystem is the key technology in the research of this paper. The algorithm is used to automatically search a optimization test paper that satisfies the user’s restriction. The genetic algorithm is based on the theory of biologic evolution, and it has whole optimization searching function by working in a similar way as biologic evolution, such as the natural selection, heredity, mutation, so the examination subsystem adopted the genetic algorithm to automatic compose test paper meantime.In order to make Genetic Algorithm more adapt to the strategy of automatic composition test paper. This paper provides a method to improve the Genetic Algorithm. Genetic Algorithm in the use of automatic composition test paper, the effect of composition test paper and genetic algorithm control parameters have great relevance, the last article on the main control parameters of genetic algorithm to conduct the experiment, using Matlab tools the corresponding data results, and its results were analyzed to explore the control parameters influence the results of the composition test paper.
