What does the migration theory include?

The migration theory includes the following contents:

1, positive transfer: refers to the situation that the knowledge and skills of the previously learned language have a positive impact on the learning of a new language, for example, two languages * * * share similar vocabulary or grammatical structure.

2. Negative transfer: refers to the situation that the knowledge and skills of the previously learned language have a negative impact on the learning of the new language, such as the learners misusing the previously learned grammatical structure or vocabulary in the new language.

3. Partial transfer: refers to the situation that the knowledge and skills of the previously learned language only partially affect the learning of the new language. For example, although there are similarities between the two languages, some language structures are used in different ways in different languages.

4. Transfer: When learning a new language, learners can apply the effect of new language learning to the learning and use of other languages through the language knowledge and skills they have learned before.

Transfer theory refers to the theory that when learning and using a foreign language, the previously learned language knowledge and skills have an impact on the learning and use of a new language. Transfer theory holds that when learning and using a new language, the previously acquired language knowledge and skills can help learners understand and use new language materials, and may also have a positive or negative impact on learners' acquisition of a new language.

Transfer theory provides important theoretical support for foreign language teaching, and also reminds learners to pay attention to the relationship between language learning and use, and correctly evaluate and apply the influence of previously learned language knowledge and skills on new language learning and use.
