Design And Implementation Of Digital Lesson Preparation System For Children's Education

According to the 13 th Five-Year Plan of National Educational Informatization,it is clearly required to promote the modernization of educational content and teaching methods.Compared with that in the middle school and university stages,the construction of information education in children's stage is rather less developed,which embodies the lack of high-quality digital lesson preparation means and material resources,the lesson preparation mainly through the convention means,PowerPoint and ineffective share of these high-quality resources.In order to improve the efficiency of digital lesson preparation,the quality of lesson preparation and teaching,the design and implementation of digital lesson preparation system for children's education,undoubtedly,has become the research topic of this thesis.Considering the digital lesson preparation system and classroom teaching requirements for children's teachers,this thesis has designed and implemented a digital lesson preparation system for children's teaching.The author's work mainly includes the current research home and abroad,the requirement of the system and feasibility analysis of the theme;For the sake of a quick lesson preparation,the author analyzes the application scenarios of using Bluetooth and OID technology,together with talking pen,intelligent education terminal,lesson preparation card and resource book;The author designs the system function model,the software architecture and business process of digital lesson preparation system for children's education;Besides,the authors finishes the general design of the system,the specific design of each module in the system and database design.The applied technology which accomplishes the courseware through HTML5 and presents it to the reader on the browser can make an interactive fusion among the words,pictures,graphs,audio,videos,color,innovation and the educational ideas.The author applies the SDK of Android system to carry out the application program development of the lesson preparation system,bringing about a good user interface and sense of experience;The authors applies the SQLite database to store content data and manage a large number of courseware which can be transferred to the file system;The author applies the MySQL database to realize the management of the background data information of lesson preparation;The author applies the OID optical characteristics and image recognition technology to facilitate the access to the lesson preparation courseware information printed with dot matrix code;The author applies the Bluetooth database to facilitate the access to lesson preparation courseware information printed with dot matrix code and realize the instant information interactive transmission between OID code value data and intelligent teaching terminal.The digital lesson preparation system for children's education studied in this thesis is helpful for children's teachers to alleviate their burden of the lesson preparation and to increase the efficiency of doing the work and to make their accomplishment and share of their lesson preparation through the digital information technology.Through good background system management,the system can do an effective management of the different users and the content of the courseware.What's more,it can also continuously optimize itself through the data analysis.To sum up,the system can contribute to great convenience to teachers' lesson preparation and teaching and bring in practical significance and great value for the implementation of educational informatization.
