Abstract: “Internet +” model, which is driving dramatic changes in all aspects of teaching and education field, provides abundant teaching resources and teaching methods for experimental teaching. The characteristics of experimental teaching resources under the background of “Internet +” are analyzed, and the strategy of “five-step method” is proposed and implemented for precisely integrating teaching resources, which greatly enhances and improves the sense of situation and participation in experimental teaching, and realized the “five-combination” characteristics of experimental teaching in inorganic chemistry. Meanwhile, the innovation of teaching model was carried out, the online and offline mixed teaching mode based on the concept of CDIO is adopted, students complete experimental projects through the stages of conception, design, implementation and operation, giving full play to their subjective initiative, cultivating their awareness of innovation, and improving their independent learning ability and the ability to analyze and solve problems.
