Exploration of mixed teaching of engineering cost under the background of “Internet+”: —Take social students in higher vocational colleges as an example

In recent years, under the background of “Internet+” and the policy of expanding enrollment of one million, the number of social students in the expansion of enrollment has increased rapidly, which puts forward new requirements for mixed teaching. This paper first analyzes the problems existing in the current mixed teaching of social students of engineering cost in higher vocational colleges. Then, in the context of “Internet+”, the mixed teaching of engineering cost social students in higher vocational colleges is combined from the integrated design of mixed teaching, video design for pre-school and pre-class instruction, and combination of “asynchronous classroom and synchronous classroom” online teaching, exploring elasticity, flexible and diverse offline teaching, building a problem feedback mechanism, diversified all-round evaluation and assessment system, and the supervision system of blended teaching, with a view to cultivating highly skilled talents who integrate theoretical and practical knowledge for the society.
