Compared with the traditional teaching mode, private one-to-one foreign teachers have many significant advantages. One-to-one foreign teachers come to the door so that children can learn without going out. In the pure English teaching environment, the class time and place are relatively free, the class environment is not disturbed, the class time arrangement is more reasonable and humanized, and the face-to-face communication is more smooth and free.
Children usually learn English after their mother tongue has been mastered. English learning is our second language learning. Krashen, a famous American language educator, holds that the key to language acquisition is sufficient understandable input. There should be enough input. To acquire a new language structure, it is not enough to rely on a few exercises and a few short essays. It needs continuous and interesting extensive reading and a large number of conversations to be effective. This method is also called Jaguar children's English learning method, as well as the domestic immersion learning method, which are very good learning methods.
而有大量的可理解輸入的環境并不代表就可以學好了，因為這一過程還受許多情感因素的影響。語言輸入必須通過情感過濾才有可能變成 語言“吸收”。影響習得語言的情感因素有：1.動力。學生的學習目的是否明確，直接影響學習效果。目的明確則動力大，進步快;反之， 則收效甚微。2.性格。自信，性格外向，樂于置身于不熟悉的學習環境，自我感覺良好的學習者在學習中進步較快;3.情感狀態。主要指焦慮和放松。焦慮感較強者，情感屏障高，獲得的輸入少;反之，則容易得到更多的輸入。
The environment with a large number of understandable input does not mean that you can learn well, because this process is also affected by many emotional factors. Language input must be filtered by emotion before it can become language "absorption". The affective factors affecting language acquisition are as follows: 1 Power. Whether students' learning purpose is clear or not directly affects the learning effect. Clear purpose leads to great motivation and rapid progress; On the contrary, it has little effect. 2. Personality. Learners who are confident, outgoing, willing to stay in unfamiliar learning environment and feel good about themselves make rapid progress in learning; 3. Emotional state. It mainly refers to anxiety and relaxation. Those with strong anxiety have high emotional barrier and less input; On the contrary, it is easy to get more input.
Many foreign teachers have always stressed the need to master scientific methods in learning a language. Only scientific teaching methods can achieve good learning results. In schools or cram schools, it is impossible to completely guarantee an undisturbed learning environment for pure mother tongue. Private one-on-one foreign teachers can not only ensure the mother tongue learning environment, but also take into account the independence of students, so as to teach students according to their aptitude.
