Abstract: In response to the current epidemic situation, major universities have launched online teaching, and "offline to online" teaching has brought challenges and opportunities to course teaching. How to use new technology to transform the traditional classroom-based teaching mode into an information-based classroom-based teaching mode is a problem faced by many courses. Combining first-class curriculum construction and advocating student-centered instructional design, we took the business economic statistics course as an example to analyze how to use the Chaoxing learning platform to effectively achieve the ingenious connection before, during and after class, teacher-student interaction and student The interaction is closely combined with the teaching interaction and teaching mode, and it is hoped that the business economic statistics course will be better presented to students online.

Key words: Chaoxing, Interconnection + interaction, Business economic statistics, Teaching mode
