Second Language Acquisition

Introduction For many years, language teachers, psychologists and others have a variety of perspectives on how to acquire languages. There are various models for second language acquisition, including cognitive-based model, socio-cultural model, and model for input and interaction. In this paper, my goal is to adopt an interactive model, which is an outstanding SLA model, to determine the actual performance of the model in the classroom. I am trying to answer the following questions: How does interaction support development between languages, as demonstrated in SLA's research?

Second language acquisition (SLA), second language learning, or L2 (language 2) acquisition is the process by which people learn a second language. Second language acquisition is also a science field devoted to studying this process. The second language acquisition field is a sub-field of applied linguistics, but we also receive research in various other fields such as psychology and education. The central theme of SLA research is interlanguage and the language used by learners is not only the result of the difference between the languages ​​they already know and the languages ​​they are learning but also the complete language system. It has its own authority and has its own system rule. When a learner touches a target language, this inter-language language develops gradually.

Learning and learning of the second language is defined as acquisition and acquisition of the second language once mastering of the mother tongue or first language is established. Second language acquisition (SLA) is a process of learning other languages ​​in addition to their mother tongue. For example, children speaking their mother tongues begin learning English at the beginning of school. I will learn English through the learning process of the second language. In fact, young children can learn second language earlier than adults learn the same language.

The important difference between first language acquisition and second language acquisition is that the process of second language acquisition is influenced by the language already learned by the learner. This effect is called language transfer. Language transition is a complex phenomenon due to the previous linguistic knowledge of the learner, the interaction between the target language input they encounter and their cognitive process. Language transfer can occur not only from the learner's mother tongue but also from the second language or the third language. Also, language transfers may occur in grammar, pronunciation, vocabulary, discourse, and reading, not limited to a specific language domain.
