Problems and solutions faced by ideological and political education in the era of big data is the focus of this study. Big data is no longer limited to random samples, no longer limited to the collection of information with a small amount of information, big data has enough "big" information to reflect the development of the situation. At the same time, this kind of data acquisition relying on technical means can be carried out without affecting the learners, and can then eliminate the interference from learners themselves and the experimental environment, and this paper gives the novel applications inideological and political education.
