What does mirror demonstration mean?

When kindergarten teachers teach children to dance, teachers often say, "Next, we will give them a mirror demonstration of dancing". Many children don't understand it, and even some adults don't know it very well. So what does mirror demonstration mean?

Mirror demonstration means that the teacher demonstrates the actions in front of the children. When the children see the teacher's actions, demonstrating the actions in the left and right directions needs to be just the opposite of what the children learn to do, just like the actions made by themselves in the mirror. This means mirror demonstration. Because of the low level of children's spatial orientation perception, the specific development trend is: three-year-old children can distinguish up and down orientations, four-year-old children can distinguish front and back orientations, and five-year-old children can begin to distinguish left and right orientations with themselves as the center, but it is difficult to distinguish each other's left and right orientations, and generally they can't master them until they are seven or eight years old. Therefore, teachers should do "mirror demonstration" when doing demonstration actions for young children.

Mirror demonstration means that the teacher demonstrates actions in front of the children, and the children regard the teacher as a mirror, and the children and the teacher learn these actions just like learning in front of the mirror.
