“Dig where you stand” 5. Proceedings of the fifth International Conference on the History of Mathematics Education

The First International Conference on the History of Mathematics Education took place in Iceland in 2009. In the Proceedings, the editors expressed their expectation that the research on history of mathematics education would be sufficiently productive to warrant the continuation of this conference every two years. And indeed, participation has grown, from 35 participants and 18 presentations in 2009, to 65 participants and 40 presentations in 2017, at the Fifth International Conference on the History of Mathematics Education. The venue of the Fifth Conference was the historical University Hall of the University of Utrecht in the Netherlands. The Descartes Centre and the Freudenthal Institute, both part of the University of Utrecht, and the Dutch Association of Mathematics Teachers sponsored the organisation and the Proceedings of the conference. The Local Committee, consisting of Heleen van der Ree, Harm Jan Smid, Jan van Guichelaar and Jenneke Krüger, organized the conference in an excellent manner. The final editing of the Proceedings was in the capable hands of Nathalie Kuijpers
