Bringing Nordic mathematics education into the future. Proceedings of Norma 20, The ninth Nordic Conference on Mathematics Education

The story about the NORMA20 conference is the story about a conference that had to be postponed, as a pandemic prevented us from coming together to present and discuss our research. When we made the decision to postpone just after Easter in 2020, we were all sad and disappointed that all the efforts made by authors, reviewers, LOC and IPC members might be for nothing. However, during 2020, digital solutions for cooperation emerged so we could host NORMA20 as an online conference in June 2021. Delaying the conference had both positive and negative consequences. On the positive side, postponing allowed us to make a call for contributions in both 2019 and 2020, substantially increasing the number of submissions. Not only was the number of submissions large but the number of accepted submissions also increased. During the conference, 72 regular papers, 30 short communications, nine poster presentations, four keynotes, and one working group were presented. This made the NORMA20 conference the largest NORMA conference to date.
