Design And Implementation Of Expansion System For Teaching Assistance Based On The Android Mobile System

Recently,wireless mobile computing technology,blue tooth and WAP have matured gradually.The mobile communication and computer technology are merged constantly.Therefore,a new concept---Mobile Learning appears in educating field.It is the extension of E-learning,people's reflection for education and professional development demands in economy society,the expression for extensive job mobility and tight time in modern society,the application for mobile communication in the education,and embodiment for human's new studying style and self-improvement.The mobile learning is considered as a studying mode in the future;that is a necessary mode.Just a few years,mobile learning has become an important area for educating research at home and abroad.The realization of assistant system for mobile learning calls for the support of intelligent mobile platform.In recent years,Android which is based on the Linux Kernel and developed by Google has developed very quickly.It stands out from numerous intelligent mobile platforms.It has features of high penetration,low cost and easy achievement.Therefore,the paper chooses it as the platform for the extension of system mobile.The paper does a deep research on the present teaching assistant system in college.In the meantime,it studies how to expand informatization teaching assistance to teaching environment which is outside traditional class,taking advantage of the Android mobile client:convenient to carry and high penetration.The client make the informatization adapt the features and development of vocational education and educational mode with features of vacation get more informatization.Firstly,this paper starts with the development of intelligent mobile platform;it introduces the development background,social demands and meaning of the system;it summarizes the extended system of teaching assistant which is based on the Android mobile client;it explains the main technological means involved in the development process.Secondly,the paper uses the object-oriented systemic analysis method;it illustrates the functional requirements of system;it puts forward the general design project of system according to system goal and demand analysis;it designs and realizes the data structure of expansion system,based on deep analysis for original data structure of college.Then,the paper observes and analysizes the mature software(eg.QQ and Weixin)that run on Android system at this stage.The humanized client that runs on Android system and applied in mobile devices is designed.In addition,the module can be realized on mobile client.As required,the module should have the functions as follow:class record,real-time discussion group and course resources browsing and so on.Thirdly,the paper presents development environment,development modes and operating environment for the realization.And it states the realizing means of all the modules in the system and testing condition by the combination of text and flow chart.It proves that the design of paper can merge into teaching management system,and succeed in the expanding original teaching system based on the Android mobile client by complete interface testing.Finally,after the aggregating testing result of every aspect,the paper concludes the advantages and disadvantages of system that runs in practice...
