Abstract: With the developments of science and technology, the main modes of experimental teaching have become diversified. Experimental courses play indispensable roles in higher education. Experimental courses are not only the basis of students' practice, but also the transformations from knowledge understanding to scientific research. The outbreak of the Corona Virus Dissease 2019 (COVID-2019) was accidental, which caused unprecedented difficulties to the experimental teaching. A series of emergency methods, such as video or online teaching, the use of digital resources, the transformation of teaching modes, and the adjustment of evaluation system, achieved good effects on the experimental teaching, including well cooperation with the related theoretical courses, the improvement of students' self-learning ability. The epidemic situation of COVID-2019 has raised some thoughts on the development of experimental teaching in the universities. The experimental teaching should be devoted to the talent cultivation and persistent innovation.
