基于Struts的网上辅导系统的设计与实现 PAGE PAGE ii 基于Struts的网上辅导系统的设计与实现 摘 要 传统的课后辅导是在课后，老师和学生同时找一个时间和地点，面对面的进行辅导。由于在时间，空间场所和广泛性上都有一定的局限性，所以很难对每个学生都进行辅导。与传统的辅导方法相比，网上辅导系统的开通，将实现教育资源的开放，使得学习者在任何时间、任何地点都能够利用互联网络进行学习，实现课堂教学的延伸。一方面，学习者可以共享他人的成功经验，吸取他人的失败教训，做到事半功倍；另一方面，教师可以通过本系统对学生进行超越时空的指导，同时，通过数字化环境下新型教学模式的运用，将有利于学习者养成自觉获取知识的习惯。 Struts是基于模型视图控制体系(MVC)的Web应用框架。本文详细介绍了基于MVC体系的Struts工作原理,探讨应用Struts框架构建企业级应用系统的步骤及方法。并在分析Struts技术的基础上，对网上辅导涉及的知识构建、人机交互学习、网上答疑、作业批改、教学论坛和试题生成等需求做了探讨,提出了基于Struts的解决网上远程教学辅导的策略,提高了网上教学的交互性和主动性,并在此基础上实现了一个网上辅导系统,实现了教学信息网络化。 除此，访问数据库时，还用到了Hibernate技术，并详细介绍了该技术。本文还介绍了系统的数据管理。系统的数据分为用户数据，论坛数据和管理数据等等。并且对各数据库进行了举例说明。 本文建立了一个基于Struts的网上辅导系统。各个模块功能都已经实现，实验证明该系统可完成网上辅导功能。 关键词 Struts框架；Hibernate技术；java设计模式；网络辅导 Abstract Teachers guide students face to face through seeking a same time and a same location in traditional learning-assistance. Because of limitations of time and space, teachers are difficult to assist every student. Compare to traditional learning-assistance, online learning-assistance can implement opening educational resource. And it make student to study at any place and time through using Internet. It is extend of classroom teaching. On the one hand, students can share other’s successes and draw other’s lessons. On the other hand, teacher can guide students at any space and time through this system. And it is useful to student to form a habit of consciousness of study. Struts is a application frame based on MVC. This paper gives a detail account of principle of Struts based on MVC. Based on the research and analysis of the technology of Struts, the function of instructing system of web was discussed, which include knowledge constructing, interactive leaning, online replying, homework correcting, E-learning forum and producer of test questions. The Strategy of distance teaching and tutoring on web was brought forward using STRUTS technology, and the interactive and initiative of instructing on web was improved greatly. A learning-assistance system was ex
