What has the greatest influence on the effectiveness of teaching, 4 more than differences in methods or the guidelines of programs, 5 is the skilfulness of the teachers: their mentality, their ability to 6 communicate, the passion they bring to the subjects they teach, 7 the breadth of interests that make it possible for them to put 8 themselves in the students' place and feel with them. 9
Federigo Enriques 1 10Abstract This essay will illustrate Federico Enriques' vast, multifaceted efforts to 11 improve the preparation of mathematics teachers, situating them in their historic 12 context and within the framework of the cultural project that formed the basis of his 13 whole scientific output. The first part of the essay is dedicated to a brief presentation 14 of the principal steps in the history of Italy's Scuole di Magistero (teacher 15 training schools), with reference to the most significant legislative measures, to 16 the contribution of teachers' associations, and to debates among mathematicians. 17 The second part will show how Enriques' cultural project for the creation of a 18 scientific humanitas, which was rooted in the philosophy and history of science, 19 developed gradually during his years in Bologna, and how this was reflected in 20This research was carried out as part of the Project PRIN 2009, Scuole matematiche e identità nazionale nell'età moderna e contemporanea, Unit of the University of Torino. 1 See [53, p. 188]: "Più che le differenze dei metodi o le indicazioni dei programmi influisce sull'efficacia dell'insegnamento il valore degli insegnanti: la loro mentalità, la comunicativa, la passione che portano nelle cose insegnate, la larghezza degli interessi che li fa capaci di mettersi al posto degli allievi e di sentire con essi." Immediately following the constitution of the Kingdom of Italy and the establish-27 ment of an educational system at a national level, the Italian political class, which 28 included many high-level mathematicians, understood the importance of having 29 corps of adequately trained teachers in order to guarantee the formation of the 30 future ruling class of the new nation. The problem was urgent, given the fact that 31 at the time people without a degree were permitted to teach. It was only in 1906 32 that the legislation was approved regarding the legal status of teachers, making it 33 official that only those who had won a competition could teach, and that a degree 34 was required for admission to the competition [GU 1906[GU , 106, p. 2085; it was not 35 until 1914 [GU 1914, 174, pp. 4086-4101] that mathematics teachers were placed 36 on an equal footing with teachers of Italian, rectifying the inequality that had existed 37 in the system since the Casati legislation (1859). Among those who were personally 38 involved in the effort to improve Italian schools and in training teachers for various 39 levels of schools were many members of the well-known Italian school of algebraic 40 geometry. Many factors led them to embrace this commitment, although for...
