Before the pandemic (2019), we asked: On what themes should research in mathematics education focus in the coming decade? The 229 responses from 44 countries led to eight themes plus considerations about mathematics education research itself. The themes can be summarized as teaching approaches, goals, relations to practices outside mathematics education, teacher professional development, technology, affect, equity, and assessment. During the pandemic (November 2020), we asked respondents: Has the pandemic changed your view on the themes of mathematics education research for the coming decade? If so, how? Many of the 108 respondents saw the importance of their original themes reinforced (45), specified their initial responses (43), and/or added themes (35) (these categories were not mutually exclusive). Overall, they seemed to agree that the pandemic functions as a magnifying glass on issues that were already known, and several respondents pointed to the need to think ahead on how to organize education when it does not need to be online anymore. We end with a list of research challenges that are informed by the themes and respondents’ reflections on mathematics education research.

在疫情爆发之前（2019年），我们问：未来十年数学教育研究应该重点关注哪些主题？来自 44 个国家的 229 份回复提出了八个主题以及对数学教育研究本身的思考。这些主题可以概括为教学方法、目标、与数学教育以外实践的关系、教师专业发展、技术、情感、公平和评估。疫情期间（2020年11月），我们询问受访者：疫情是否改变了您对未来十年数学教育研究主题的看法？如果是这样，怎么办？ 108 名受访者中的许多人认为他们的原始主题的重要性得到了加强 (45)，具体说明了他们的初始反应 (43)，和/或添加了主题 (35)（这些类别并不相互排斥）。总体而言，他们似乎同意这一流行病就像放大镜一样放大已知的问题，一些受访者指出，有必要提前考虑当不再需要在线教育时如何组织教育。最后，我们列出了一系列研究挑战，这些挑战是根据主题和受访者对数学教育研究的反思得出的。
