Information and Student Achievement : Evidence from a Cellular Phone Experiment

This paper describes a field experiment in Oklahoma City Public Schools in which students were provided with free cellular phones and daily information about the link between human capital and future outcomes via text message. Students' reported beliefs about the relationship between education and outcomes were influenced by treatment, and treatment students also report being more focused and working harder in school. However, there were no measureable changes in attendance, behavioral incidents, or test scores. The patterns in the data appear most consistent with a model in which students cannot translate effort into measureable output, though other explanations are possible
