As parents of children, online English training for children is recognized. In fact, I didn't know much about online children's English training at first, but later I couldn't go to English training classes because of my children. I got to know this industry by chance. In this industry, their teaching methods are also varied, including one-to-one children's English, one-to-many children's English, and one-to-two children's equivalent classes in a training institution. Among many choices, I first chose children's online one-on-one English. One-to-one English for children is chosen because when people think the price is high, the effect should be good. But after studying for two or three months, the effect is not as good as I expected. At first, the children's enthusiasm was very high. Later, the children's enthusiasm began to change and they stopped learning actively. When communicating with children, children mean that they feel that they are interacting with teachers every day, but this interaction is like asking questions in children's eyes. Over time, children's enthusiasm is not as high as it was at the beginning. But a child inadvertently mentioned that it would be good to have a partner to study with, which made me start to reflect on whether it is really useful to choose one-on-one English training for children online. After that, I began to look for a more suitable platform for children, so I found that the one-to-two peer-to-peer class of children's English in training institutions made me a little excited. Children's English 1 Peer-to-Peer classes in training institutions will definitely improve children's understanding of English.
