Many infants and children around the world grow up exposed to two or more languages. Their success in learning each of their languages is a direct consequence of the quantity and quality of their everyday language experience, including at home, in daycare and preschools, and in the broader community context. Here, we discuss how research on early language learning can inform policies that promote successful bilingual development across the varied contexts in which infants and children live and learn. Throughout our discussions, we highlight that each individual child's experience is unique. In fact, it seems that there are as many ways to grow up bilingual as there are bilingual children. To promote successful bilingual development, we need policies that acknowledge this variability and support frequent exposure to high-quality experience in each of a child's languages.
Incidents of prejudice and discrimination in K-12 schools have increased over the past decade around the world, including the U.S. In 2018, more than two-thirds of the 2,776 U.S. educators surveyed reported witnessing a hate or bias incident in their school. Children and adolescents who experience prejudice, social exclusion and discrimination are subject to compromised well-being and low academic achievement. Few educators feel prepared to incorporate this topic into the education curriculum. Given the long-term harm related to experiencing social exclusion and discrimination, school districts need to create positive school environments and directly address prejudice and bias. Several factors are currently undermining progress in this area. First, national debates in the U.S. and other countries has politicized the topic of creating fair and just school environments. Second, the Covid pandemic has interrupted children's and adolescents' education by halting academic progress which has particularly negatively affected students from marginalized and ethnic/racial minority backgrounds. Third, teachers have experienced significant stress during Covid-19 with an increase in anxiety around virtual instruction and communication with parents. Three strategies recommended to address these converging problems include creating inclusive and non-discriminatory policies for schools, promoting opportunities for intergroup contact and mutual respect, and implementing evidence-based, developmentally appropriate education programs designed to reduce prejudice, increase ethnic and racial identity, and promote equity, fairness and justice in school environments.
