The Instant Data Analysis And Its Visualizational Implementation In Digital Classroom Quizzes

The instructional feedback is an important part of the instructional communication process, and it is also one of the key factors that influence the instructional effectiveness. Quiz is a common and effective way of the feedback in classroom, and it is an integral part of the instructional process. Quizzes analysis is a process to infer the students learning by collecting their information in the quiz. However, the previous quizzes analysis depends on the teachers’subjective judgment and instructional experience, which not only affects the timeliness and objectivity of instructional feedback, but also does harm to teachers to adjust and improve instruction in time.With the support of new technologies and equipment, the approach of instructional feedback and classroom quizzes has achieved a qualitative leap. But the existing classroom instant feedback system and the digital test system represented by online examination system both are not suitable for classroom quizzes and its analysis. In addition, the fast incremental data of classroom instruction has brought the problem of information overload. To solve those problems, this study integrated the advantages and characteristics of the classroom instant feedback system and the digital test system, used the visualization technology, designed and implemented an instant analysis system for classroom quizzes. The system can obtain scientifically accurate quiz data, and provide timely and reliable visual feedback information with digital technologies, and it is aimed at making the analysis of classroom quizzes from empirical summary to scientific research.The study used the methods of literature research, learning response information analysis research and developmental research, in view of the domestic and overseas research and theories relatedly, according to the actual needs and technology available, carried out the detailed design and development work, implemented the instant analysis of classroom quizzes data and its visualization, and explored its application preliminarily.First of all, based on analyzing the main problems and shortage of the existing classroom instant feedback system and the digital test system, the paper reviewed the related literature of the technologies of classroom instant feedback, the digital test and the visualization of educational information, defined the concept about visualization technology and classroom quizzes, and expounded the related theories from communication, education and psychology. Then the paper analyzed and designed the environment and processes, the data model, the instant analysis model and its visualization, to build up the integrated model for the digital classroom quizzes. On this basis, the study implemented the instant data analysis system on the pad of Android system for digital classroom quizzes, and the paper explained the specific processes and technical details, introduced the instructional function of the five instant analysis methods of the system. Finally, the study designed the mode of the classroom quizzes instant feedback with multi-device interaction, and discussed the instructional enlightenment and problems that may arise in the process of the system applications.
