The 2015 Indiana Mathematics Education Research Symposium (IMERS) was held on March 27, 2015. The symposium is a way to support mathematics education graduate students and educators to present research and receive feedback from mathematics education faculty and other graduate students from across the state. The symposium invites proposals that describe research studies at various stages – completed work, work-in-progress and studies currently under design. This fourth IMERS Symposium was hosted by the mathematics education faculty at Indiana University Bloomington, Indiana University-Purdue University Indianapolis, Purdue University, Indiana University-Purdue University Columbus, and HAMTE.
