This study examined how intensive use of information and communication technology (ICT) both in and out of school affected the development of 18 Finnish students' ICT expertise over three years. Researchers found that students' ICT skills increased over time and differentiated, with some students emerging as technically-oriented or socially-oriented "experts". These experts helped less skilled peers, supporting their own motivation. The intensive ICT environment fostered both individual learning and social community, supporting adaptive expertise development.
