Post-Covid Teaching of Physics Experiments Through Flipped Classroom & Blended Teaching Practice at College

The outbreak of COVID-19 in 2020 has changed the teaching methods of Chinese education to a large extent with the explosive development of online and blended teaching. With the normalization of the pandemic, teaching has gradually entered the post-pandemic era. Online teaching greatly limits the scope of physics classes where experiments have to be conducted, instruments manipulated and interaction between students and teachers is needed. Therefore, blended teaching has become a breakthrough point in the reform of physics experiment teaching in college. This research focuses on students majoring in Food who are taught experiment physics using a blended teaching method based in a flipped classroom. After the end of the semester, a Questionnaire Star was used to conduct a qualitative and quantitative analysis. The survey found that 93.4% of the students acknowledge this teaching mode, with a majority of them declaring that this teaching mode improved their learning efficiency as well as their understanding and mastery of knowledge and problem-solving ability. It showed that blended teaching should be the norm, not the exception. The survey also found that the effects of watching previews before class determined the degree of learning in the classroom to a certain extent. This means that an emphasis must be put on optimizing the previews’ contents as well as coming up with more efficient instruments to ensure students watch the previews.
