With the prosperity and vigorous development of online education industry, it is inevitable that there are similarities among brand organizations. For example, the characteristics of foreign teachers' English training have become the same characteristics of most online English education institutions in the market. With such homogenization, parents will inevitably make a mistake. How to choose the same one? 1, teacher differences Although many online platforms are English training for foreign teachers, there are differences among foreign teachers themselves. First of all, it is easy to distinguish foreign teachers, but where foreign teachers come from needs textual research. After all, some platforms can invite authentic European and American foreign teachers, but it does not rule out that some platforms will invite foreigners from other countries to make up the number in order to save costs. In addition, the qualifications of foreign teachers also need to be verified to prevent individual platforms from putting foreigners with no educational experience on the platform and misleading children. Children's English training institutions have strict access to foreign teachers, all of which are selected by foreign teachers' management teams in Europe and America. Foreign teachers must hold the double certification of international professional English teaching qualification and have rich experience in children's English education, so as to create an authentic European and American educational environment for children and let them feel the pure English language environment. 2. Textbooks are different from foreign teachers, and teachers are basically qualified. At this time, it is necessary to consider the teaching materials as an auxiliary tool for English education. If the teaching materials are properly selected, the educational effect of English training for foreign teachers can be further improved. However, many online children's English institutions directly follow the original international textbooks or make appropriate localization modifications on the basis of foreign textbooks, and a few will conduct research and development according to European and American standards. In fact, foreign textbooks are designed for children in Europe and America, without considering the study habits of children in non-native countries, and are directly used by children in China. The learning effect remains to be seen. In view of this, the original Oxford textbook EverybodyUp is the main teaching material for children's English in training institutions, and the teaching material content design system is comprehensive, novel and interesting. English courses specially designed for children in China not only combine the characteristics of European and American education, but also adapt to the English learning process of children in China, which is the icing on the cake for foreign teachers' English training.
