This exploratory study investigated young children's beliefs and opinions about computers by actively involving children in the research project. Fifty two children, four to six years old, were asked a set of questions about their favourite activities and their opinions on computer use before and after a seven month computer intervention implemented by the researcher and two more teachers. Results are differentiated in terms of intervention and non-intervention group and children's computer access at home and at school. Findings suggest that young children like using computers very much but not more than other popular activities. More positive opinions and attitudes for children in the intervention group and less positive attitudes for children who used computers only at home were identified. Implications for further research and for both teachers and parents are highlighted.
