I am an associate professor of mathematics education at the
Department of Mathematics and Statistics at the University of New Hampshire.
I received my Ph.D. in Mathematics Education from Technion, Israel Institute of Technology. My doctoral research was funded by the Israeli Ministry of Education through a special scholarship for excellent doctoral students. Prior to pursuing my doctorate, I taught high school mathematics in Israel for 8 years.
My research interests are broad, with a primary focus on teaching and learning mathematical reasoning and proving at the secondary level.
I study both the cognitive and social aspects of students' mathematical reasoning and justification processes, aiming to understand how teachers can support students' development of mathematical reasoning and argumentation skills. As a teacher educator, I am particularly interested in the knowledge and professional support that pre-service and practicing teachers need to create learning environments that promote justification and proving.
My research also includes instructional design and the creation of curriculum materials that provide students and teachers with opportunities to practice mathematical reasoning, argumentation, and proving. I have coauthored secondary mathematics textbooks and contributed to a resource book on Calculus for teachers.
