Book review of Didattica della matematica by A. Baccaglini Frank, P. Di Martino, R. Natalini and G. Rosolini
In recent years, the Italian school system has undergone a radical process of evolution that is transforming it, necessitating urgent reflection on the training of mathematics teachers. The book under review aims at offering some basic tools for pedagogical research, which in our opinion is necessary but not sufficient.
