Book excerpt: For several decades, parent-child cognitive interaction researchers have acknowledged that children learn cognitive skills in the context of their social and early environments. These cognitive skills are often imparted to the children by parents or parenting others in formal or informal settings. Thus, for example, such informal settings as dinner table conversations, walks through grocery stores, museums, or neighborhoods become rich laboratories for children to learn varied cognitive skills ranging from numeracy, concepts, and language. The way in which those learning opportunities are provided by parents, structured by parents and scaffolded by parents may well vary depending on culture, and other socio-demographic variables; and may well vary depending on formal or informal settings. The aim of this Research Topic is to bring together scholarship from both global north and global south contexts which explores how children learn via parental involvement in formal and informal settings.
