The Program

Conference Title

A Tribute to the Career of Dr. Judith Sowder: Linking Research and Practice in Mathematics Education


Work in the field of mathematics education ranges from the theoretical to the practical. Occasionally a scholar develops the research expertise to serve as a leader in the field and, simultaneously, has the passion and commitment to find ways to link a deep understanding of research with critical issues of practice. Professor Judith Sowder is a personification of such a commitment. The presentations at this conference will address issues related to linking research to practice in mathematics education and pay tribute to a colleague whose leadership was instrumental in promoting the field nationally, while committed locally to SDSU‚s Center for Research in Mathematics and Science Education.
