Design And Implementation Of WEB Assisted Instruction System

With the development of social economy,the assisted teaching management system is widely introduced into the teaching management process.It has become an important issue that how to integrate courseware,test and the exchange of information between teachers and students,and finally form a flexible learning system with the coexistence of stand-alone and network modes.On the basis of analyzing the common assisted teaching system,this thesis develops the auxiliary teaching software in combination with the actual situation of the unit.This paper analyzes the design and implementation,present situation,development trend and existing problems of the WEB-based teaching system,which includes the application system development platform Java,the system development tools NetBeans,the system database Java DerBy and the system multimedia technology JMF.In the demand analysis stage,firstly,the history and current situation of the new learning system are investigated.Secondly,the feasibility of the system design is verified through the analysis of the system requirements.Thirdly,on the basis of demand analysis,the system is designed and implemented,and the sub-modules are designed in detail to verify whether they are feasible and reasonable.Fourthly,the individual modules are designed and optimized separately,such as the system optimization design of the teacher teaching activity module.Finally,the entire platform is assembled and tested.In the process of design and development,the design of the project focuses on the main idea of software engineering and makes full use of the advantages of the project management.The case diagram is given in the demand stage,and the flow chart of the system is provided in the design stage.In addition,in the implementation phase,this paper gives the system block diagram and so on.During the period of project practice,the system realizes the assembly and the testing of the platform.Meanwhile,each module achieves the pre-envisaged effect.The designed platform not only can increase the students' learning ability and efficiency,but also can reduce the teacher work pressure.In addition,it also provides an example for the progress of relevant items.
