摘要

Data visualization can convey unlimited information in limited space, and display intuitively the internal relationship between data, which is conducive to the discovery of implicit information. Use data visualization technology and tools, the teacher can visually process teaching content, intuitively and dynamically display teaching content, improve teaching level and efficiency, achieve expression superiority of "one figure is worth thousand words". Visualization supports students' cognitive construction. According to visual processing and analysis results of learning process data, the student can find the gap, adjust learning plan, change learning strategy, and promote autonomous learning, build their knowledge framework and association system. According to analysis of teachers and students data by data visualization technology, the teaching managers can timely adjust objectives, methods and strategies of teaching management, to better promote the management process and level of school. Data visualization technology is a powerful tool for future education, to promote teaching reform and optimize teachers' technology application.
