**Conference for the 30th anniversary**** ****of the French**** ****association**** ****femmes et*** ***mathématiques**** ****(Women and Mathematics)**** ****on « The Teaching of Mathematics: what**** ****can be said today about the differences between women and men ? », Paris, September 29-30, 2017**

**On the occasion of its anniversaries every 10 years, the association ***femmes et mathématiques*** has chosen to organise some conspicuous event. For the 10th anniversary in 1997, a one-day conference was organized about four remarkable contemporary women mathematicians, Yvonne Choquet-Bruhat (first woman elected at the French Academy of Science in 1979), Jacqueline Ferrand (1918-2014), Paulette Libermann (1919-2007) and Marie-Hélène Schwartz (1913-2013). For he 20th anniversary, in 2007, the first extensive statistical data pointing out the « disppearance » of women full professors in pure mathematics in France were shown by Laurence Broze and Véronique Chauveau. Moreover it was the first time that the works of the psychologists Steven J. Spencer, Claude M. Steele and Diane M. Quinn (1999) and Pascal Huguet (2002) about the stereotype threat were displayed before a large audience of mathematicians in France, as a tentative explanation for explaining the poorer performance of women in mathematics.**

**In 2017, for the 30th anniversary of the association, a two-day conference was organised: its objective was to try to understand the (mutiple) reasons why women tend not to go to higher education programs with a fair amount of mathematics though they are rather good students in all subjects, including mathematics and science, and all the way to the end of high school.**

**This conference was a big success, more than 100 people were present both days, especially some people in responsability at the ministry for national education (primary to high school education), which is a little bit unusual in France. It shows the importance, for people in responsability at the higher level in France, of the question « why so few women in mathematics and in science ? ».**

**Anne Boyé (Centre François Viète, Nantes) and Michèle Artigue (Laboratoire André Revuz, Université Paris Diderot) discussed the differences in the mathematics education for girls and boys in the 2nd half of the 20th century and gave some comparisons in the international framework.**

**Valérie Berthé (Institut d’informatique fondamentale, CNRS and Université Paris Diderot) gave a wonderful talk about the Dynamics of Pisot Type and quasi-crystals.**

**The other talks discussed different points, such as the education of teachers, the performances of the students in mathematics in the terms of gender, the PISA study, the gender stereotypes in science and in mathematics. **

**The exhibit « Women of Mathematics throughout Europe, a Gallery of portraits » was inaugurated during the conference at the Institut Henri Poincaré and stayed there through the month of October. See ****http://womeninmath.net**
