History of Mathematics for Teachers: The Case of Irrational Numbers.

Abstract

c) Active learning The material is prepared in worksheet form. Participants read the sources and work by themselves (or in small groups) with some guidance, through questions, exercises and problems especially prepared for each historical source. d) Conceptual history The history relates to how a concept evolved, the different approaches by mathematicians in the past, their difficulties, their mathematical creativity, up to the formalization stage. A small dose of facts, dates, biographies and anecdotes enter incidentally.
