Research on the construction of precise ideological education system in higher vocational colleges under big data technology

In order to improve the accuracy and effectiveness of the civic education in higher vocational colleges and universities, this paper adopts big data technology to build a multi-level civic education system, and optimises the education strategy through data collection, modelling analysis and personalised feedback. The results show that the education system based on multi-dimensional data enhances students’ participation in learning and the effectiveness of civic education, and is able to track students’ ideological changes in real time, improving the effect of personalised support for education.
