Design And Implementation Of The Classroom Interactive Tool Based On IOS

In nowadays informationalized age, it is an important task for the development of education that using technology to improve education model to improve the quality and efficiency of teaching in the world’s countries. With the rapid development of mobile intelligent terminal devices, mobile Internet technology and resources, mobile learning has become an essential way of learning in the future. iOS mobile operating system has advantages in running smoothly, elegance and pureness, application quality and secure of system, so it is the general trend of informationization in education and is in line with the market demand of current learning environment in our country that building an interactive learning terminal application on iOS mobile platform.Classroom interaction emphasizes on mobilize students to learn and maintain a positive initiative to improve teaching effectiveness, and it shows diversity, convenience and perdurability, two-way extensiveness and strong infection in the background of education informationization. The Classroom Interactive Tools for iOS is the student’s terminal tool of the teaching platform called StarC, developed by the National Engineering Research Center for E-Learning. It communicates and exchanges data with the teacher’s terminal of StarC. Students and teachers perform real-time interactions of various teaching information and data through the Classroom Interaction Tools, to achieve all-round interaction between teachers and students and meet the needs of informationalized classroom teaching and interactions.The iOS classroom interactive tool can be divided into several sections including handwriting, question interaction, document interaction and so on. They complement each other and serve the digital classroom interaction together. By means of analysing the practical demand of the task, formulating the communication protocols and interactive data format, and comparing the pros and cons of various technical solutions, the optimal technical route is determined and put into programming implementation. During development, following main technologic problems have been solved:the use of heartbeat mechanism and the implementation of long-running network connection with the server has enhanced the interaction’s stability in wireless network environment; custom drawing methods has made up for the shortcomings of the system’s draw method and has promoted the artistic and fluent features of drawing; the use of partial refresh principle has ensured fluency of a large number of handwritten. The functions and performances of the application performance have been tested and evaluated professionally and systematically and the App has been successfully submitted to the App Store.The Classroom Interactive Tools for iOS has been used in some schools along with the teacher’s terminal of starC teaching platform, which promotes the integration of mobile learning and classroom interaction and make a certain contribution to the informationalized classroom interaction between teachers and students.
