Network information “spheres” is a new situation of the current college ideological and political education, which provides college students with a relatively independent and closed access to information, thus rendering it more difficult to perceive and guide thecollege students, thinking. College ideological and political education is severely challenged by the adverse influence caused by college students’weakened selfselection ability, educators’undermined information superiority and authoritative status, the disrupted social mainstream ideological transmission and the spread of online “dissension” in network information spheres. Facing the difficulty and challenge, the college ideological and political educators should establish and perfect the guiding mechanism of ideological and political education, attach importance to college students’predominant status, and innovate their work methods and ways. Only in this way, can they provide a perfect system guarantee for campus information supervision, break the informationbarrier between educational subject and object, and enhance their guidance force in the network information spheres.
