Abstract: “Micro-area network ideological and political education” is a concept based on the notion of precision. It is a kind of network ideological and political education for a specific range of student groups or individuals, featuring small range and high precision. To be precise in ideological and political work, a multi-dimensional model, which includes layers of task, resource and judgement, is established, using new media and big data. Based on the model, micro-area network ideological and political education can be implemented. In the process, by drawing data portrait of individuals, analyzing index of specific states and carrying out early warning for critical items, problems are identified precisely; through precise supply of teaching resources in general education and precise assistance measures in individual counseling, aims are achieved precisely. By these methods, ideological and political work becomes more efficient, more effective and more predictive.
