Exploration and Practice of Online Teaching of “Inorganic Chemistry II” Based on MOOC

: During the battle against COVID-19 epidemic, the inorganic chemistry teaching team of Jilin University carried out online teaching of student-centered “inorganic chemistry II” course based on “inorganic element chemistry” MOOC with Chaoxing learning platform and QQ group as the auxiliaries. Through the big data support and interactive communication section of Chaoxing learning platform, the learning situation of students in the three learning links of “pre-class, in-class, after-class” was timely tracked and analyzed. Practice showed that online teaching could accomplish teaching and learning effectively.
