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.
而有大量的可理解输入的环境并不代表就可以学好了，因为这一过程还受许多情感因素的影响。语言输入必须通过情感过滤才有可能变成 语言“吸收”。影响习得语言的情感因素有：1.动力。学生的学习目的是否明确，直接影响学习效果。目的明确则动力大，进步快;反之， 则收效甚微。2.性格。自信，性格外向，乐于置身于不熟悉的学习环境，自我感觉良好的学习者在学习中进步较快;3.情感状态。主要指焦虑和放松。焦虑感较强者，情感屏障高，获得的输入少;反之，则容易得到更多的输入。
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.
