This research, carried out in Human Institute of Information Technology with a number of teachers and students as its subjects, sets out to give statistical analysis upon the students' selections of online teaching platforms as well as their evaluations of online teaching. At the same time, based on the online teaching practice of ?Building Structure?, a certain quantity of research upon the online teaching practice is completed among the students who began their college studies in engineering cost in the year of 2018. According to all these studies, it is evident that multiple factors such as teachers' ages, professions, and the features of various online teaching platforms, can determine which one is used by different individuals. The evaluation results suggest that online teaching is necessary under the impact of the epidemic despite the fact that students may face a series of problems for lack of self-control and other possible reasons. Through practice, an innovative teaching and evaluation method can partially solve the problems found in online teaching and provide useful ideas for creating higher quality teaching on the Internet.
