Information technology and student achievement: evidence from a randomized experiment in Ecuador

This paper studies the effects of information and communication technologies (ICT) in the school environment on educational achievement. To quantify these effects, the impact is evaluated of a project run by the municipality of Guayaquil, Ecuador, which provides computer-aided instruction in mathematics and language to students in primary schools. Using an experimental design, it is found that the program had a positive impact on mathematics test scores (about 0.30 of a standard deviation) and a negative but statistically insignificant effect on language test scores. The impact is heterogeneous and is much larger for those students at the top of the achievement distribution.
