Final answer:
Research indicates that growing up in a bilingual home tends to enhance language development, aligning with the idea that humans have a biological predisposition to learn languages. Studies show that bilingual students often progress better in language learning compared to monolingual peers, especially during the critical period of early childhood.
Step-by-step explanation:
Effects of Growing Up in a Bilingual Home on Language Development
When students grow up in a home where two languages are spoken, research suggests that their language development is enhanced. This enhancement provides them with the advantages of bilingual education. Studies, such as those conducted by Johns Hopkins University, have demonstrated that students who learn in both their native language and a second language tend to make better progress than those taught only in one language. Furthermore, growing up bilingual aligns with the concept that humans are biologically predisposed to language acquisition which indicates a biological readiness for learning multiple languages from birth.
Children across different cultures display a consistent order in learning language structures, regardless of being bilingual or monolingual. Contrary to some beliefs, bilingual children are not at a disadvantage; rather their proficiency is likely a testament to the astounding cognitive abilities that all children possess in learning language. Research also indicates there is a critical period during early childhood that is optimal for language acquisition, during which bilingual exposure can be particularly beneficial.
Therefore, assertion 2) that 'Their language development is enhanced' aligns with the contemporary understanding of bilingualism and language development supported by a wide range of linguistic research, challenging the misconception that bilingualism might lead to delays or negative effects in children's language skills. Exposure to multiple languages from an early stage not only aids in language development but can also enhance cognitive skills and offer social and cultural benefits.
