I. Introduction
System Engineering is a public elective course of our school, which is practical and comprehensive, and students have difficulty in understanding and using it. In order to effectively solve the problem of students not being able to attend classes due to the epidemic, we promoted the "suspension of classes without suspension and teaching without stopping" in an orderly manner. Taking the teaching unit of systematic analysis as an example, the author carries out task-driven teaching design based on BOPPPS teaching model, and explores how to improve students' learning enthusiasm and learning effect.
