Dr. Ji-Won Son joins the Department of Learning and Instruction as an Assistant professor of Mathematics Education in August 2013. Prior to that she spent five years as an Assistant Professor at the University of Tennessee at Knoxville. She received her doctorate from Michigan State University in 2008 with an emphasis in mathematics education. Moreover, she spent four years teaching elementary and middle school students in South Korea.

Her research centers on the intersection of mathematics education and curriculum and instruction. The four main research interests she has developed are: (1) mathematics textbook analysis (learning opportunities provided to students by textbooks), (2) teachers’ curriculum use (how teachers read and use mathematical curriculum and textbooks), (3) teacher learning (how pre-service and in-service teachers learn to interpret and respond to student thinking), and (4) international comparative studies (whether there is any difference in students’ mathematical learning opportunities and teaching approaches among different countries).

She is currently working on two externally funded research projects. The first project is funded by the Spencer Foundation, which seeks to identify, from a cross-cultural perspective, the core mathematical knowledge and practice for teaching algebraic and functional relations, to enable middle school mathematics teachers to better develop students’ algebraic thinking. Her second project is funded by the Cullen Foundation. In this project, she seeks to provide a new summer Math program to 150 girls at Buffalo's Futures Academy, Enterprise Charter School, and Westminster Community Charter School (ages 10-14 yrs, entering grades 5-8), to reinforce basic math skills and improve critical thinking and reasoning skills, specifically relating to fraction operations. By providing project-based learning, she intends to examine how participating students expand their mathematical knowledge and develop STEM identities and agency within and beyond their participation in the summer math program.

Her work can be found in publications such as *Educational Studies in Mathematics, Journal of Mathematics Teacher Education, The Journal of Mathematical Behavior, Mathematics Education Research Journal, The International Journal of Mathematics Education (ZDM), Teaching Children Mathematics, and Mathematics Teaching in the Middle School*. Currently, she serves as an editorial board member of *Journal of Educational Studies for Educational Research Institute* and *International Journal of Education*.

**Recent Funded Grants**

**Core Mathematical Knowledge and Cross-cultural Teaching Practices in Algebraic and Functional Relations**(PI: Ji-Won Son) by the Spencer Foundation (2016–2018)

The purpose of this project is to identify, from a cross-cultural perspective, the core mathematical knowledge and practice for teaching algebraic and functional relations, to enable middle school mathematics teachers to better develop students’ algebraic thinking. This study has the potential to advance our understanding of high-quality mathematics teaching practices for 6th-7th grade algebraic concept development.

**Fostering Equitable Mathematical Experience: Project-Based Learning for Under-represented Girls**(PI: Ji-Won Son) by the Cullen Foundation (2016-2017)

The purpose of this project is to provide a summer Math program during July 2017 for 150 girls at three schools in Buffalo and examine how participating students expand their mathematical knowledge and develop STEM identities and agency within and beyond their participation in the summer math program.This project was featured in UBNow.
