As a public basic course of the whole university, "College Computer" has the characteristics of many class hours and large class size. In view of the learning characteristics during the epidemic, I used asynchronous SPOC to reorganize the teaching arrangement of our school's existing MOOC, and divided the curriculum into two parts: "centralized learning" and "autonomous learning". First of all, uniformly publish various teaching resources, teaching plans, teaching organization methods, etc., to ensure that every student can clearly understand online teaching methods and learning requirements; Secondly, make full use of existing online video resources (MOOC, SPOC, etc.), transplant online and offline hybrid teaching to online, and attract students to the virtual "classroom" all the time through live teaching, centralized video learning, classroom exercises, discussions and other interactive links provided by MOOC, and keep abreast of students' knowledge; After class, use the SPOC platform and the class QQ group to carry out online self-test exercises, forum discussions, online question answering and homework exercises, and regularly publish learning status reminder notices to keep in touch with students. "Mu Classroom" connects centralized learning and autonomous learning, as well as activities of students and teachers. This kind of organization can effectively use online resources, not only guarantee the quality of teaching, but also effectively improve students' knowledge mastery.
