The document summarizes key findings from a research project that looked at the impact of student to computer ratios in 997 schools across 49 states, finding that lower ratios improved various education success measures. It identifies important implementation factors for successful one to one programs such as principal leadership, teacher training, and frequent integration of technology into core subjects and assessments. Potential reasons for one to one programs failing include simply deploying devices without meaningful changes, lack of network support or professional development, and multi-user devices instead of single-user tablets.
