The degree reached in the mastering of reading acknowledge is one of the elements of success or failure at secondary education level. A good number of pedagogical tools are nowadays available to meet the difficulties that may arise. But, on one hand these tools take little account of the latest research about the act of reading and, on the other hand, have been but little submitted to evaluation. We have tested a pedagogical process for the improvement of the reading capacity which uses the computing tool. This process devotes a great part to drilling activities which aim at improving the speed of reading as well as the understanding of the texts which are read. Even if they reveal a few changes in the abilities of the individuals, the results we could notice are far from meeting our expectations. Beyond that evidence, our observations also comfort the idea that the reading concept actually implies various mental activities which cannot be evaluated as a whole and which require specific pedagogical treatment.
