Abstract

The invention discloses a dynamic visualization method and system based on big education data. The method comprises the steps that massive teaching process data is collected from an on-line teaching platform; the collected education data is transmitted to a server to be stored, and an education data base is formed; dimension reduction processing is conducted on high-dimensional data in the data base; according to a request of a visualized display terminal, the dimension needing to be presented is queried, and the corresponding data is mined out from a data storage layer, wherein the visualized display terminal is used for dividing the big education data into different dimensions according to the requirements of different users and conducting visualized displaying on a result fed back by the server. According to the method and system, massive complex big education data is displayed in a simple, efficient and visual mode, and the difficult problems such as teaching process quality management, student study and growth monitoring and intelligent education management decision making are assisted to be solved.

Description

technical field [0001] The invention relates to the field of educational information display, in particular to a dynamic visualization method and system based on educational big data. Background technique [0002] In the era of big data, the value of educational data is being re-recognized and evaluated by educators. Educational data is no longer just a bunch of simple "numbers" used for statistics, it is becoming a strategic asset and scientific power to transform education. With the fermenting of the concept of big data in the world, developed countries represented by the United States, the United Kingdom, France, etc. took the lead in using big data as a new type of strategic resource, and regarded it as "the oil of the future". With the rapid development of global education informatization, education data is increasing geometrically. In addition to the data generated by traditional school education, the Internet education market is also generating massive amounts of ed...
