First of all, we need to understand the teaching experience of foreign teachers. In fact, many foreign teachers have certain English professional ability, which is enough to cultivate and teach children. The most important thing for us to choose a foreign teacher is to see the teaching experience of the foreign teacher. The most intuitive way is to listen to the foreign teacher's lectures. A powerful foreign teacher will show his best in the process of lectures. Even if we don't know the standard of a good foreign teacher, we can feel the difference between different foreign teachers from their lectures.
Then we should cultivate children's interest. In order to make children happy, many foreign teachers overuse classroom games. We should pay attention to this. We should reasonably grasp the proportion of fun and learning.
Moreover, the teaching materials used, what kind of teaching materials children use, what kind of content they learn. So when we choose a pure foreign language children's English training institution, we should look through the teaching materials. If there is only one teaching material for a year, then the knowledge that children can learn is not much. There should be a whole set of teaching materials, which can be used step by step, suitable for children's different English levels, and the teaching materials should have four aspects of listening, speaking, reading and writing, so that children can develop in an all-round way. At present, some children's English training institutions do not have teaching materials. They think that children's English learning is very simple and does not need teaching. We use children's English textbooks, not only for children, but also for foreign teachers, so that they can be systematic in class.
