Design And Implementation Of Billing System Based On Mobile Situated Learning

The quick development of the mobile data service would multiply the merit of the mobile situated learning in terms of time and region.In the future,it may become a mainstream learning mode and make the traditional classroom learning abandoned.Because the mobile situated learning are becoming more and more popular,the mobile situated learning would be inevitable to evolve to paid sharing system where how to formulate standards for payment to teacher against mobile environment and how to master the charging mode would become a problem which the paper would discuss how to eliminate.Several teacher pricing modes and models had been delivered before,the paper would design an applicable teacher pricing model on the base of the mobile situated learning and the teacher fee pricing theory.The design and implementation of the system would make the teacher pricing mode applied in the real life.For this purpose,the paper would apply the mobile situated learning theory and use Android platform as assistant tool to design and apply a charging program which aims at the teacher under mobile learning mode based on the teacher online consulting system to Improve the function of teacher online consulting system.About the research content of the paper,the system mainly functions providing the teacher the charging standard for mobile situated learning when the teacher provides online consultation.Meanwhile,it would provide economic return to the teacher who provides exchange and interaction service.It would enhance the interaction between the user and the teacher and also at the same time excite the enthusiasm of the teacher to improve his teaching quality.After logging in the system,he teacher may fill his personal information.After completing the personal information,the teacher will be priced according to the teacher's personal information by system.Through matching teacher's title,the system gets the initial charging standard and grade of teacher online consultation,and makes reasonable management of teacher consultation pricing through the integration grade system.More than that,the system also realizes the time-based charging for the online consultation between the user and the teacher.In the minutes for the cycle,the teacher pricing results for billing standards,the student account for each minute deduction.After the online consulting,students can evaluate teachers on the basis of online advice.The system will manage the teacher's scores according to the grade of teacher evaluation,and the teacher's account will receive the fees for the consultation.In the structure of the thesis,first,by referring to the literature and online data,it introduces the research background,research significance,research content and thesis organization structure of the paper,and relatively detailedly introduces the mobile situation learning theory,billing system and system development background which will be used in system design and development;secondly,taking the way of questionnaire investigation and literature analysis,the teacher's consultation pricing is divided into three parts of teacher's default pricing,teacher's grade division and teacher's integral management to analyze,and the teacher consultation pricing model is established;thirdly,combining the theory and characteristics of the mobile situation learning,the user analysis and demand analysis of this system are proposed.And based on the requirements analysis and the characteristics of the system,taking the C/S architecture and the MVC development pattern to conduct the outline design,module design and database design for the system.Designing the system's design principles and overall development model,analyzing the function and contact of each module in teachers' terminal,making the various modules that used in the data table;for the second time,combining the design situation of server-side and client in the system design,using the Android platform technology to develop and implement the data layer,the logical layer and the control layer of server-side and the client's various modules and functions,and showing the relatively core pseudo-code and data,while showing the results of the system implementation with the view interface;finally,the design and implementation's work of the parper is summarized and having an expectation for functions that failed to achieve at the present stage.Through application situation of procedure in the market,adjusting teachers consulting pricing model and studying the optimization of system interface,the network quality's guarantees of the learner and the teacher,reduction of the data transmission quantity and so on.
