基于“超星泛雅平台+学习通”快速完善课程的技巧和实践

Due to COVID-19, all the universities in China has postponed their spring semester. The Ministry of Education issued a call "suspending classes without stopping learning" to require universities to carry out online teaching actively. Up to now, Online teaching has been implemented for nearly eight weeks, and teachers are familiar with online teaching methods. Then, how to hold online courses efficiently and refine course resources have become the main tasks for teachers. This paper elaborates on the practice and skills of rapid improvement of online course and interactive teaching based on "Chaoxing fanya platform and Xuexitong". Using these skills can not only reduce the workload of teachers, but also build high-quality online courses to ensure teaching quality and objectives. This paper could provide a reference for college teachers to implement online teaching efficiently.     

有机化学在线课堂教学实践探索

The spring semester of 2020 is affected by the new coronary pneumonia epidemic, which prevents the normal classroom teaching of universities in China. Nankai University actively responds to the request of "Suspended classes but not stop teaching and learning" proposed by the Ministry of Education. The online teaching software such as "Rain Classroom" and "Tencent Meeting" are used to provide online teaching to undergraduate students. This article takes organic chemistry teaching as an example and introduces the implementation process and effectiveness of online teaching. According to the particularity of online teaching, teachers must change the teaching mode to ensure the teaching work carried out effectively.
