The goal of this study was to examine the impact of a one-to-one program on the implementation of learning skills, information literacy, and the usage of computerized tools among students. These skills are part of the demands placed upon schools to develop 21st century competencies. Seventh and ninth grade students participated in this study (N=181). One group had routinely studied in 1:1 classes with personal laptops (Intervention group) and others studied in regular classes with no ICT (Comparison group). The research tool consisted of a complex, computer-based learning task. Completion of the task required implementation of skills such as information retrieval, information evaluation, reading comprehension, information processing and representation, and knowledge presentation. Findings indicated that students from 1:1 classes performed significantly better than students from the comparison group. Their higher competencies were manifested in the final score as well as in skills such as organizing information in a table, evaluating information and its reliability, quality of argumentation, and representation and presentation of knowledge while using computerized tools. These results indicate, on the practical level, the positive effect of learning with personal laptops and routinely available ICT on students' achievements and competencies.
