Abstract: Based on the characteristics of resource sharing, form modernity, communication speed, channel diversity, virtual timeliness and other characteristics of the modern network environment. It is not only necessary but also feasible to make full use of the network to carry out the second classroom of “basic” courses. In the network environment to organize the second classroom teaching of “basic” courses, the following practical paths can be adopted: First is to optimize the network resource library of the second classroom of “basic” courses to realize the organic link between online and offline hybrid teaching; Second is to build a network scenario simulation platform for the second classroom of the “basic” courses with the breath of modern life, to realize the organic blending of abstract ideas and specific cases; The third is to establish a rapid response mechanism for the two-way interaction between teachers and students in the second classroom of the “basic” courses to achieve the organic unity of explicit education and implicit education for teachers and students; Fourth is to adopt a variety of online media to activate specific teaching activities, and to realize the organic communication of unified activities and decentralization of teachers and students; Fifth is to organize students to reproduce the real life scenes of daily moral cultivation and law-abiding at any time, so as to realize the teaching practice of morality and law-abiding by teachers and students.
