Wowang machines can play a certain role, but they can't play a leading role. Many teaching details need to be made up by other learning methods in order to achieve the ideal learning effect. At the same time, it is very necessary to use the registration line of Wowang class machine to attend classes. It is also a delicate job to enroll children in classes, and you can't just choose. We need to combine the children's learning reality to see which aspects are weak, so that we can find online courses that are better at teaching in this area to make up for the shortcomings of children's learning. This is the experience that I summed up when I enrolled my children in classes to learn English. You can make a reference.
