Abstract:Deep integration of Internet+ with education and teaching has promoted a rapid development of online teaching such as micro-class and MOOC. Online teaching has the advantages of rich contents and flexible teaching arrangement. The traditional offline classroom teaching has the advantages of strong interaction, timely feedback, and emotional teaching. How to utilize their respective advantages becomes an important topic for "Golden Course" construction in the new era. Considering key online and offline teaching complementary links, a BOPPPS based online and offline blended teaching scheme was proposed, including “pre-class knowledge autonomous learning; in-class knowledge internalization; post-class knowledge enhancement”. The appropriate case teaching and interactive teaching methods were introduced into the scheme. The teaching reform practice was carried out in the "Engineering Economics and Management" course and shows that the new teaching scheme and methods stimulate the student learning initiatives, meet their hierarchical learning needs, and improve the actual teaching quality. The research results can provide reference for the blended teaching “golden class” construction.
