This exploratory research project was aimed at developing baseline data on computer habits and behaviours among preschool children in Singapore. Three sets of data were collected from teachers, parents and children which are (1) why and how young children use computers; (2) what are the key physical, social and health habits and behaviours of children when using the computer and (3) what is the role of adults during children's computer use. The information gathered from the study can be used to inform teachers, parents and other stakeholders on preschool children's computer habits and behaviours and if necessary, to develop preventive programmes to protect preschool children against potential physical, health and social risks of computer use as well as address any potential negative habits or behaviours as early as possible and before they have an impact on their later schooling years.
