UOOC平台与腾讯课堂相结合的“在线异步教学”

The COVID-19 broke out on a large scale, and online teaching became the first choice for teachers. Avoiding network congestion and ensuring learning effects are the dilemmas faced by online teaching. With the help of the UOOC platform and the Tencent Classroom, taking the "Polymer Structure and Performance" course as a sample, we suggested a new "online asynchronous teaching" model. Among them, the SPOC course is convenient for students to manage their learning time; "Chapter Quiz" and "Student-to-Student Mutual Evaluation" are helpful for students to obtain multi-angle feedback; project tasks are focused on case analysis so that students carry out inquiry-based learning. Overall, the "online asynchronous teaching" model breaks the time and space restrictions on teaching and learning, guarantees the quality of teaching during the epidemic, and lays the foundation for creating a "golden class".
