a huge epidemic storm swept through

it has caused great impact on various fields in China. As the epidemic situation continues to grim

China’s Health Committee has officially included Novel Coronavirus’s pneumonia as a class B infectious disease. As of March

more than 10000 people have been infected

and the overall epidemic is still spreading. In order to achieve effective control of the epidemic

most provinces in the country launched a level-1 response mechanism

many provinces that were affected by the epidemic

issued special measures on delaying the resumption of work. During the epidemic response period

the opening time of education was delayed

and it was an inevitable objective fact to use online classes to carry out teaching. However

online course education is a double-edged sword

which has advantages and disadvantages. How to correctly solve the existing problems has become a key problem for teachers.
