Abstract
Doing significant research is critical to building the quality of mathematics education research. But doing substantively significant research is inherently difficult because we are studying the unknown. The ability to clearly articulate or ‘sell’ the significance of our research often poses even a greater challenge to researchers. Nevertheless, without such statements of significance we are unlikely to win grants or have papers accepted for publication. In this presentation, I consider what it means when we say that research is significant. My reflections draw upon my own experiences and those of others as part of a ‘deep dive’ in search of significance in mathematics education research.
