This incident also tells us a truth, that is, how important the map of teaching materials is. Because when primary school students read textbooks, if they are all written, they will feel very boring. Learning is a very boring thing. Without any pictures, they may look like they are going to sleep. And good pictures can make teaching materials more vivid and children will be more involved in learning. This is a fact. If we open an article, if we see that it is full of words, then maybe you are not interested in reading it.
When we open a text, we see a vivid illustration in the middle or at the end of the text, so according to some information in the illustration, we just want to know what the text is written. This is completely based on science. We can verify this fact, take out the child's textbook and turn to some parts without illustrations to see what he is like. He will never be so active. So in general, a picture of a text is very important, it can make children relax and devote themselves to learning.
