Abstract: The rapid development of the big data industry has brought challenges for colleges and universities to cultivate big data innovation and application-oriented and technical skills talents. Therefore, colleges and universities need to adapt to the changes in the era of big data, open and optimize big data management and application courses to improve students’ professional competence. Aiming at the data visualization technology course, this article first explores the implementation plan of the course from the three levels of theoretical perception, software teaching and case simulation, combining theory with practice to improve students' professional skills; then designing the assessment plan of the course, comprehensively and comprehensively evaluate students' mastery of theoretical knowledge and practical operation level in order to improve the teaching effect and optimize the teaching mode of combining theory and practice under the background of big data.

Key words: Big data, Visualization, Implementation plan, Assessment method
