You don't have to be an expert to deduce that if our students are doing very poorly in calculation and reading, they would need to increase (and intensify) the hours of mathematics and language, from primary to secondary school. This is as evident as it is complicated to rectify in the short term. Precisely, the latest innovations have stolen the spotlight from these two basic areas of knowledge and have been sacrificed (or mixed) with other proposals that are perhaps more attractive to students, but which PISA results confirm are distancing us dizzyingly from the minimum requirements.
