This presentation summarizes 25 years of research on teaching and learning statistics. This is done through stories of research projects I have been involved in, all of which involved collaborations with colleagues who have made important contributions to the research and from whom I have learned many important lessons. I discuss these projects in terms of the research questions addressed, the methodologies used, the results and implications, and the importance of my collaborators in each project.
