Design And Implementation Of Core Modules In Electronic Schoolbag

The21st century is an information technology era. People’s thoughts and habits in this eraare experiencing disruptive change. Education field, especially in the traditional teachingmedia and the way, has also been an unprecedented impact. In order to realize theinformatization, individuation and diversification of education mode, to improve enthusiasmand creativity of teachers’ teaching and students’ learning, electronic schoolbag program arisesat the historic moment.In the past of the education system, classroom became the only place for teachers andstudents to communicate. Books became the only carrier of the knowledge. Homework wasthe only way in which teachers and students interact. As the Internet, especially in tablets andsmart phones as a representative of a new generation of mobile network application of rapidpopularization, the traditional model got a fundamental change, the spread of information isnot restricted by time and place. Mode of electronic schoolbag is to set up a communicationplatform, teachers and students have become the knowledge dissemination of medium andcarrier, again and again. Firstly, electronic schoolbag solved the previous education place andthe time limit, at any time convenient teacher and student interaction. Secondly, it solves thelimitation of knowledge carrier, the students don’t have to as the growth of the school andconstantly update the book, we just need to download the corresponding electronic textbooks.Thirdly, teachers can grade the students homework, alleviate the teachers’ teaching pressure,improve the teachers’ work efficiency and teaching effect. Finally, parents can according tothe platform to communicate with teachers in time, reach the role of teachers and parentsdouble care for students. All in all, electronic schoolbag for students, teachers and parents is awin-win-win result.In the view of the above requirements, this paper designs and realizes a workbookmodule of electronic schoolbag in the system the most core. Combining with a series ofauxiliary module, we formed a complete electronic schoolbag, which has realized the threeline of interaction among teachers, students and management.In this system, the system classed three roles of administrators, teachers, students. Basedon three kinds of characters, we designed and realized the corresponding function module. First, the administrator module, concrete into account Settings, class Settings, send andreceive notification and assessment statistics, used to manage all user accounts (teacher,student), and to set all the class. In the teacher’s module performance statistics, exammanagement, check the notification, and other functions, to classroom assessment,management of students, grade of student work, for the registration of students’ examinationand a series of work. Finally, student module settings, as homework, see result, off grade, anda series of sub function.Our system brings to Android platform, based on Web Service architecture to implementthe information interaction between electronic schoolbag and the remote server. As some keytechnologies, such as Android graph processing technology, CursorAdapter methodimplementation real-time interface updates, Web services architecture implementation, Areaof the screen capture technology when assignments submitted and Android message pushtechnology etc. A series of questions were discussed in detail, illustrates the specific flowchart and database system of E-R diagram. On the basis of the detailed implementation ofthe system is the main interface, operation and test are discussed. Finally, pointed out the needto perfect this system, pointed out the direction for future work.The core module design and implementation of electronic schoolbag, has very broadapplication prospects and good social and economic benefits. At the same time, some keytechnology is also discussed in this subject to a similar development work has certainreference significance.Chapter1(introduction) we describe the concept and the application background of theproblem. Further discussed the demand analysis. This study reviewed the related to subjectthis topic about development present situation at home and abroad, and a series of problems inthe process of development.Chapter2(background) We introduce Android background platform of this topic, andAndroid for research on interface design related problems, and describes in detail the datainteraction of Web Service technology.Chapter3(overall design) We include the design idea of this system, division andimplementation of each function module design, system work flow analysis, and architecturesystem of the database aspect, the E-R graph of each data table etc.Chapter4(administrator module design and implementation) We describe the overallintroduction of the administrator module function and design and implementation of the related function, the key technology introduction of the design process and code analysis.Chapter5(teachers and students module design and implementation) We expounds theintroduction of whole module function and the function of the specific design andimplementation, and the implementation interface technology of real-time updates.Chapter6(design result and analysis) We introduce the system architecture and technicalsupport of this study, further shows the main functions of operation interface, the problemsencountered in the process of development were summarized.Chapter7(conclusion and further work) We summarize the main work of this system hascarried on the objective analysis and evaluation, prospect the research in the futuredevelopment.
