The Institute for Didactics of Mathematics of the University of Klagenfurt is happy to announce that the 11th International Mathematics Education and Society Conference will take place in Klagenfurt, Austria, from 24 September 2021 to 29 September 2021. We are currently planning the conference in spite of the corona crisis and stay optimistic that we can meet in person. Our goal is to organise a conference that allows for the sharing of insights and for intense debate in a nice environment, while staying cost-friendly and inclusive. Further information will be announced here and via the MES mailing list (to which you can subscribe by emailing to David Wagner). For now, stay healthy and critical!
