Abstract: Precision teaching is widely used in the teaching of different courses for its "precision" advantage. However, due to the limitations of technical conditions, the traditional precision teaching is not widely applied in practical application. The rapid development of big data provides an opportunity for the wide application of precision teaching. Under the support of big data, research on the construction and implementation strategy of precision teaching mode, and its application in geography classroom, can not only improve teachers' information literacy, exercise their teaching ability, but also promote cooperation between students and improve students' learning ability.

Key words: Big data, Precision teaching, Model construction, Application
