Abstract: With the rapid development of Internet information technology, more and more online teaching tools and platforms have emerged, which have been widely used in classroom teaching. Especially after a semester of online teaching practice, we realize that the traditional teaching mode needs to be reformed and innovated. At the same time, we also find that there are some problems in online teaching, such as unclear teaching design objectives, confused teaching content, and insufficient students' learning autonomy. Based on these problems, under the background of the Internet, according to the theory of new constructivism, this paper formulates the principles of curriculum teaching design, and combines with the characteristics and teaching requirements of financial market, and makes a detailed teaching design in the aspects of teaching mode, teaching environment and teaching resources, so as to explore more scientific and reasonable teaching methods and enhance students' learning initiative And autonomy, hoping to further improve the teaching effect.
