  At the beginning of the 900s Guido Castelnuovo turned his attention toward
methodological, didactical, historical and applicative issues. He was an active
member of the ICMI (International Commission on Mathematical Instruction) and
of the Mathesis, an Italian association of mathematics teachers. He also was
the author of the mathematics curricula for the new Modern Lycee and he taught
the first University courses devoted to preservice training of mathematics
teachers. His course on Precision and Application Mathematics, inspired by
Felix Klein, shows Castelnuovo's point of view on mathematics and presents a
higher point of view on the programmes of the Modern Lycee.
