This document summarizes research from a 3-year experiment in Israel on introducing 1-to-1 computing in classrooms. The experiment involved 14 classes with grades 4-6. Results showed improvements in effective learning time, reduced discipline problems, and teachers taking on more supportive roles. Students reported more engaging and relevant learning, deeper engagement and motivation, and increased self-efficacy. The research also outlines lessons learned, including the need for ongoing teacher training, technical support, relevant digital content, and sufficient annual funding per student. Remaining challenges include the traditional assessment system and getting the Ministry of Education to become a learning organization.
