The Design And Implementation Of Luoding Middle School Electronic Classrooms Software System

With the application of information technology education in schools, the primary and middle schools are capable to build the computer network classroom. Aiming at related issues for the management of network digital device and class teaching, this thesis takes the computer network classroom in Luoding middle school for example, analyze and design the requirement in the network classroom teaching. Also the computer programming is used to realize the software system in the electronic classroom, which addresses the management of series of devices and raises the management efficiency in class teaching. Comparing to the emphasis on the hardware electronic teaching construction, the electronic classroom software system has positive meaning in advancing the school electronic teaching. For the study and realization of electronic classroom software system, this thesis analyzes and describes the domestic and oversea electronic classroom software system to determine the target and content of the software system. The thesis is divided into three parts, i.e., the theory and technology research and selection, analysis and design of software systems implementation, and testing of software systems.In the study and choosing of theory and technology, the thesis emphasis on the analysis of data compression and network programming technology, the discussion and choosing of efficient data compression and rapid network transmission. For systems analysis and design, the feasibility of the system implementation is analyzed in the system analysis process, and the hardware and software systems architecture is analyzed in requirement analysis. A questionnaire paper is designed to investigate the system functional requirements, then we draw the flow diagrams and system case diagram for electronic classroom software system data.In the system design process, we stratify layers to determine the functions of the software functional model pictures. The StartUML is adopted to design system class diagram. The two aspects, conceptual and physical design, are used in system required database design. In the system realization and testing, the system realization process analyze and realize the three key technologies which are namely the data compression, screen broadcasting and data transmission. Classroom teaching management module is taken for example to analyze function module process and write the implementation code. System testing process analyzes software testing related technologies, designs software testing strategy, and treats the testing results.Electronic classroom software system has been capable to solve the problem of a computer network classroom teaching. Whereas to improve the software efficiency from a technical point of view, a further plan is to expand the scope of software, perfect the functions and other extension aspects.
