Parental Involvement in Language Development: A Comparative Synthesis of Bilingual and Monolingual Children
摘要
Parental involvement is a critical determinant of young children’s academic, socio-emotional, and cognitive development. This paper synthesizes research on bilingual and monolingual children aged 3–8, emphasizing how parents shape language, literacy, and cognitive outcomes through distinct practices. An inductive synthesis approach is employed within an integrated framework combining Vygotsky’s sociocultural theory, Bronfenbrenner’s ecological systems theory, the Home Literacy Model, Sameroff’s transactional model, and Paradis’ bilingual-specific perspective. Findings indicate that both bilingual and monolingual families engage in shared reading, storytelling, and structured literacy routines, yet they differ in strategy and focus. Bilingual families adopt deliberately complex practices such as codeswitching, translanguaging, and heritage-language storytelling to balance dual-language exposure and cultural identity, supporting biliteracy and cognitive flexibility. Monolingual families typically emphasize structured, school-aligned literacy activities that strengthen early proficiency in one language, with outcomes depending on the quality and timing of scaffolding and fading. Importantly, heterogeneity within both groups, shaped by language policies, caregiver proficiency, socio-economic resources, and community context, produces divergent developmental pathways. This synthesis demonstrates that parental involvement in both contexts operates through the same mechanism of mediation, scaffolding, and internalization, though enacted with different tools and constraints. Tailored interventions are therefore essential: bilingual families benefit from heritage-language resources and scaffolding support, while monolingual families require code- and meaning-focused practices with planned fading. Policymakers and educators should strengthen the mediational ecology, reduce socio-economic barriers, and promote equitable literacy opportunities across diverse linguistic and cultural contexts.
