Abstract

Abstract:

Based on the analysis of the courses and the investigation of students' online learning needs, an online teaching mode of "Tencent Classroom" and "Rain Classroom" with "split screen" is designed. This mode is used for the online teaching of "Foundation of Innovation and Entrepreneurship" and "Chemical Instrumentation and Automation". After two months of teaching practice, the teaching and learning were reflected and summarized, aiming to improve the performance of online teaching.

Key words: Online teaching, Practice course, Tencent Classroom, Rain Classroom
