Bilingual education refers to using two languages as teaching media and mastering the language by learning subject knowledge (for example, geography, mathematics, history, etc.). In other words, bilingual education does not achieve the goal of language education through language courses, but helps learners master two languages through other subjects in school education. The basic principle of bilingual education is that teachers insist on using students' target language. Whether teaching knowledge or answering questions, teachers use the target language.

As for students, students who take part in bilingual education are fully prepared for how to attend classes. Do not pay attention to the use of language forms, but try to absorb language knowledge (sentence patterns, vocabulary, etc. You can understand this. Students have the motivation to master the target language, whether this motivation is to integrate into the future countries that use the language, or to use the language as a tool for obtaining information, interpersonal communication or other activities. In addition, in the process of getting familiar with the target language, students try to express themselves in the target language, and the scope is first limited to the classroom. When the ability and conditions permit, expand outside the classroom. However, students need not insist on using the target language. When the language ability is not enough, you can express it in your mother tongue.
