The purpose of this thesis is to study the computer using practice within pre-school activity, or more specifically, to study aspects of meaning-making as afforded when the computer is in use in pre-school. In the study a socio-cultural perspective is used as the point of departure combined with an Ecological approach to visual perception and Positioning theory. Data was collected in three pre-school units with children from 3-6 years of age. At the time of the study each unit had access to one computer. The data consists of approximately 13 hours of video-documented observations supplemented by additional field notes of the same events; nine interviews with the teachers and 38 interviews with the children. The result is structured and presented in three articles. The study sheds light on the situated valuation, which is ongoing within an institutional practice such as pre-school. The general picture of the teachers’ ways of handling the computer use is described with two main focuses: first, as constituted in the meeting between political visions and every day practice and second, as grounded in the rationality dominating within the discursive practice. In conclusion, it is argued that the dominating rationalities constitute three different meaning shaping practices, in the study labelled as protective, supporting and guiding. These environments do afford quite different possibilities when it comes to getting access to learning about as well as by the computer.
