Role of External and Internal Factors of First Language Acquisition

When children are born, they are thrown into the language world. They are exposed to various vocabulary, grammar and intonation, and they will learn the language of their carers, depending on where they live in the world. The world around them is an external factor that turns primary language acquisition into such an infant. The word is considered to be "the core element in infant's social life." (Eve V. Clark, 2009) Language is the way we communicate as human beings. This is essential to our survival.

Focus on research in this field since 1970 and check the factors that affect second language acquisition. The topic includes roles of relocation and first language, order of development, input, interaction, and output roles, cognitive and character variables including age, and official guidance and error correction role. I will prepare an English teacher for speakers of other languages. Examine the psycholinguistic foundation of the ESL reading process, provide opportunities for seminars to test leading practices in peer demonstrations, and explore the basics of testing, evaluation, and syllabus design at the ESL course. Special attention will be paid to reading and vocabulary for misunderstanding analysis and learning theory

Second language acquisition (SLA) is a relatively new field that was seen as an aid to language education before the 1960s (Myles, 2010). Ellis (1994) defines three aspects of secondary language acquisition: external factors (social factors, inputs and interactions), internal factors (learners' existing knowledge and internal mechanisms) and Individual learners' factors (p.193). Social factors were investigated under the influence of Vygotsky's developing region (ZPD). This article mainly explains the concept and application of ZPD.
