Construction and Empirical Study of Comprehensive Evaluation Index System of Online Teaching in the Period of COVID-19

The occurence of COVID-19 has directly led to the development of large-scale online teaching in China, and the quality of online teaching has become the focus of public attention. From the two dimensions of "evaluation of teaching" and "evaluation of learning", the article establishes an comprehensive evaluation index system of online teaching that includes three secondary indicators of "pre-class preparation", "in-class teaching" and "after-class feedback" with 12 evaluation factors. The empirical research on the online teaching of tourism and hotel majors shows that students both highly evaluate the online teaching platform and the effect of online teaching. It can be seen that teachers are fully prepared before class, they are responsible during the class, feedback is effective after class, and students have reached their learning goals and expectations. After COVID-19 is over, the "PAD + BOPPPS" teaching mode can be used to achieve a seamless connection from "online teaching" to "offline teaching".
