【摘要】：目前传统的教学方法很难在高校适应,不同的校区不同的学生对此需求都不一样。随着我国教育改革的不断推进,我国学校逐渐加大了在高校信息化建设上的投入。正是在这样的背景下,出现了基于网络的在线教学系统。这样的教学系统极大的改变了原来的传统教学模式,把面对面的教学形式改变为通过网络的远程直播的模式。该教学模式极大的扩展了传统教学模式的边界,提高了教学的效率,解决了教学的空间限制,是传统教学模式的有效补充。正是在这样的背景下,基于Web的在线教学系统应运而生。本系统从在线教学的实际需求出发,设计并实现了基于通用的SSH框架的在线教学系统,该系统具有系统管理、在线培训、在线考试、资源管理、老师管理、学员管理等功能。本文使用数据库mysql设计了本系统的数据模型,并通过Hibernate实现了该数据模型的对象化。然后基于通用的SSH框架实现方法,实现了系统的控制层代码逻辑,最后通过jsp实现了系统界面层。在系统部署阶段,我们使用了Tomcat服务器集群,以及Apache负载均衡技术。通过使用这些技术来满足系统的高并发性需求,在不断的调试和验证的下,达到了系统的最优,并满足了学员学习的实际需求。最后通过实际的实施充分的验证了系统的功能,满足了网上在线教学的需求。通过本系统的部署,可以提高老师的教学效率,提高学生的学习效率,并可以及时的反馈教学效果,很好的促进了教学质量的提高。
[Abstract]:At present, traditional teaching methods are difficult to adapt in colleges and universities, and different students in different campuses have different needs. With the development of educational reform in China, Chinese schools have gradually increased their investment in the construction of information technology in colleges and universities. It is in this context, the emergence of online teaching system based on the network. This teaching system has greatly changed the original traditional teaching mode, and changed the face-to-face teaching form to the remote broadcast mode through the network. This teaching model greatly expands the boundary of the traditional teaching mode, improves the teaching efficiency, solves the teaching space limit, and is an effective supplement to the traditional teaching mode. It is under this background that the online teaching system based on Web emerges as the times require. Based on the practical requirements of online teaching, this system designs and implements an online teaching system based on general SSH framework. The system has the functions of system management, online training, online examination, resource management, teacher management, student management and so on. In this paper, the data model of the system is designed by using database mysql, and the objectification of the data model is realized by Hibernate. Then the control layer code logic of the system is realized based on the general implementation method of SSH framework. Finally, the interface layer of the system is realized through jsp. In the system deployment phase, we used Tomcat server cluster and Apache load balancing technology. Through the use of these techniques to meet the high concurrent requirements of the system, under the continuous debugging and verification, the system is optimal, and meets the actual needs of students learning. Finally, the function of the system is fully verified through the actual implementation, which meets the needs of online teaching. Through the deployment of the system, teachers can improve the efficiency of teaching, improve the efficiency of students, and can timely feedback teaching results, a good promotion of the quality of teaching.
