Non technical summaryComputers and software have been gradually introduced as teaching tools in many countries. Thanks to important public and private investment, the number of schools that have access to computers and internet in the classroom has increased exponentially since the beginning of the nineties. The percentage of schools that have an internet connection has e.g. increased from 5% in 1996 to over 95% in the UK and to over 80% on average in European countries in 2001. In Brazil as well, availability and use of computers and internet in schools represents an important investment and has increased rapidly in recent years. The percentage of teachers that use the computer and internet for pedagogical purposes has increased from 12 to 38 and from 3 to 18 percent respectively between 1999 and 2003. The percentage of schools with a computer laboratory increased from 17 to 35% in the same period.The most obvious purpose of introducing computers into the classroom is clearly the promotion of computer literacy, a much-demanded skill on the labour market. However, 'computer assisted instruction' (CAI) or the use of computers as a learning tool for acquiring other cognitive skills, has come more and more under attention as well.The question we would like to answer empirically is whether the availability and use of computers and internet for schools is effective in improving test scores in maths and reading. We use Deaton's pseudopanel estimator on original repeated cross-section data to estimate the effect of the availability and use of ICT in schools in Brazil on pupils' performance. More precisely, we estimate the effect of the availability of a computer laboratory in school and the use of computers and internet as pedagogical resources by the teacher on 8 th grade pupils' test scores. We find that the availability of a computer laboratory affects test scores negatively in both disciplines and particularly in Maths. Possible interpretations are the existence of a trade-off between investing in a computer lab versus other more effective pedagogical means for schools and, for pupils, between sitting in the lab rather than doing other activities. But we also find that the use of the internet as a pedagogical resource by the teacher has a significant positive impact on pupils' test scores in both disciplines in Brazil. Therefore, we may conclude that although merely i...
