Abstract: Under the background of the popular digitization, informatization and the building of New Engineering, the innovation of new teaching mode represented by flipped classroom has become research front in education. We take the "field theory" course as the teaching reform aim, carry out online and offline teaching with the help of Chaoxing platform and mobile APP, combine the advantages of flipped classroom with traditional classroom teaching, and build a new flipped teaching model. The teaching practice shows that the design of flipped teaching does not need to be limited to one class, but can be considered by integrating the traditional classroom into the teaching length of the whole course. It is suggested that the curriculum reform should be carried out step by step, and the proportion of inquiry teaching should be gradually enhanced, while the teaching materials and related online resources should be continuously improved.

Key words: Flipped classroom, Chaoxing platform and app, Teaching pattern
