Design And Implementation Of Online Classroom Teaching System Based On SOA Architecture And ThinkPHP Framework

With the development of computer network technology,the new type of education in the information network era has become a big development direction of education reform,which is also an important work of our country's colleges and universities towards modernization education.This provides new inspiration and impetus to the development of education in our country.In recent years,colleges and universities in China continue to expand their enrollment.With the increasing number of students and the aggravation of teachers' teaching tasks,the mode of informationbased network teaching is imperative.The subject takes the practical application of online classroom teaching as the development background,adopts SOA architecture technology based on B/S model,Think PHP framework structure and data mining technology and so on to develop online classroom teaching system.First,the system needs analysis,get the system functional requirements,and use UML object-oriented modeling technology to give the system use case diagram,according to the overall system design,and then the system function module design,including teaching content management,online learning management,online examination management,student center management module,including the system database design and implementation part.The system is adopted.The improved Pick-KX load balancing algorithm can dynamically adjust the real-time load condition of the server,effectively optimize the distribution of the server resources,solve the problem of uneven load of the server nodes,and simultaneously introduce the Prim cognitive model to improve the selection function of the test questions in the online examination function.So that the online examination module can dynamically adjust the test questions according to the actual situation of the students so as to ensure that each test of the students can achieve the purpose of consolidating the learning content.Finally,the system is tested and the test results are analyzed.The on-line classroom teaching system greatly expands the space and practice of teacher-student learning communication,and is an important way to promote active,cooperative,research-oriented,autonomous learning and to form an open and efficient new teaching mode.At present,the system has been successfully used online,which to a certain extent has provided help for teaching and education in colleges and universities,and at the same time has provided more useful experience precipitation for future system improvement and upgrade.
