With the advancement of smart education in China, the core value of educational big data in promoting the development of educational innovation and scientific reform has gradually become prominent. The article constructs a practical framework of educational big data from three aspects of the introduction of educational big data projects, the construction and application of educational big data, and the data-driven precision teaching paradigm, and then proposes six major trends in the development of domestic educational big data: data will go through the entire process of teaching and assist the accurate design and implementation of teachers' teaching activities; the acquisition and analysis of all-dimensional and multimodal teaching data will become the focus of learning analysis technology; educational administrators and teachers at all levels will gradually increase their data awareness and data literacy education will receive increasing attention; the educational big data projects will be carried out in the district and schools initiatively and the company will become a core participant; the value of integration of big data and teaching practice begins to show, and public awareness will gradually increase; smart classrooms and academic assessment are the leading areas and hotspots for big data application and they will attract more attention from the government, companies, schools and parents. Finally, the article analyzes five major challenges faced by the development of domestic educational big data: insufficient data processing ability of teachers, the difficult acquisition of offline learning data, unclear school-enterprise cooperation mechanism and statutory mechanism, independent running of educational big data products, and the improvement of the scientific and accurate data analysis model. Then, this article puts forward some developmental suggestions for the construction and application of educational big data in China.
