Online English education is becoming more and more diverse and popular. Many parents still have doubts about the effect of 1 dui 2 foreign teachers' English training after they have crossed some misunderstandings about their children's English enlightenment. Does this teaching method really help to improve children's English scores? Many parents basically have a wrong view that the higher the teaching cost, the better the teaching quality and learning effect. However, there are many loopholes in the current English teaching methods in China, which makes the education level of many English education institutions uneven, and it is difficult to judge whether the teaching expenses match the teaching level. The teaching effect of expensive teaching institutions is not necessarily good. One-to-two teaching method can't judge the quality subjectively, and there are many factors to consider. 1. The difference between Chinese and foreign teachers lies in whether oral pronunciation is pure and standard. Teacher China can also help children improve their oral English, but the innate language advantage is unmatched by teacher China. Secondly, the reception of imparting knowledge is different from the direct imitation of pronunciation by foreign teachers in Europe and America, and the learning effect will definitely be very different. 2. Whether the qualification certification of foreign teachers is authoritative. They are all foreign teachers, but if foreign teachers have many years of teaching experience, they will know more about their children's study habits. What other aspects of children's learning are lacking? Where are the learning difficulties that are difficult to break through? The teaching methods provided by experienced foreign teachers for children will be more effective. Authoritative certified foreign teachers, after strict screening and teacher selection, have more high-quality teacher resources. 3. Whether the classroom teaching effect can make children enter the learning state. The teaching mode does not necessarily lie in the one-to-two teaching mode, but in whether children can integrate into the classroom and realize the idealized teaching effect from it. Children learn quickly and well, and the classroom atmosphere is active. They learn well in a relaxed and pleasant learning environment and enjoy the learning process in English class. Parents don't need to pay attention to brand reputation and advertising. Training institutions aim at teaching children English attentively and pay attention to their all-round growth. The admission rate of foreign teachers in Europe and America is less than 5%, and strict screening insists on being responsible for students. Review the guidance after class, follow up the children's English learning progress at any time, and answer relevant questions in time. One-to-two foreign teachers' English training institutions insist on doing the best education and providing the best teaching resources for students.
