Deep integration of Internet+ with education and teaching has promoted a rapid development of online teaching. Online teaching has the advantages of rich contents and flexible teaching arrangement. Offline classroom teaching has the advantages of strong interaction, timely feedback, and emotional teaching. How to utilize their advantages becomes an important topic for Golden Course construction in the new era. Considering key online and offline teaching complementary links, an improved BOPPPS based online and offline blended teaching scheme is proposed, including pre-class knowledge autonomous learning, in-class knowledge internalization, post-class knowledge enhancement. The teaching reform practice is carried out in the engineering economics and management course and shows that the new teaching scheme and methods stimulate students’ learning initiatives, meet their hierarchical learning needs, and improve the teaching quality. The research results can provide reference for Golden Class construction.
