Today's children are growing up in homes with an ever-growing array of technologies supporting families as they work, play, communicate and learn. How have recent rapid changes to the home as a technological environment influenced what and how preschool children learn? This paper, based on a series of studies of young children's experiences with digital technology at home, identifies key factors - including the structure and layout of the home, family practices, family values and family interactions - which shape the ways in which children: a) learn to use technologies; b) learn about the world via the medium of technologies; c) develop learning dispositions; and d) learn about the role of different technologies in family and community contexts
