Abstract: Big Data era is coming, which has brought not only a new way of thinking and understanding to our work, living, education and other aspects, but also a new scientific methodology to the ideological and political education of college students. Through the excavation of the digital footprint left by college students in Internet, smart phones and other facilities, we can accurately recognize their ideological and behavioral dynamics, predict their future thinking and behavior based on the previous data, master and control more accurately their ideological dynamics and behaviors, so as to achieve more precise and scientific ideological and political education for college students.

Key words: big data; college students; ideological and political education; methodology
