With the rapid development of the Internet，the teaching reform in Regular IHEs (institutions of higher education) is imperative. Blended teaching is the best choice for the theory-practice teaching of Inorganic Chemistry in local universities in short semesters and periods. In the process of the reform of Inorganic Chemistry teaching in local universities, theory and experiment teaching are conducted separately by different teachers, and there are many problems. This article proposes a blended teaching model of theory-practice co-construction and the use of gradual progress in the implementation. The method of two firsts is rationalized in order to avoid repeated explanation of knowledge points, reduce students' academic burden, stimulate students' interest in learning, enhance the overall improvement of teaching quality. And it also provides some references for other universities to carry out the teaching reform of inorganic chemistry.
