Valentina Postelnicu

FACULTY PROFILE I received my Ph.D. in Curriculum and Instruction – Mathematics Education from Arizona State University. I teach mathematics and mathematics education courses for future teachers. My research interests focus on mathematics education, specifically student and teacher understanding and difficulties with mathematical concepts, as well as the ways the mathematical content changes in various contexts. I also investigate the teaching and learning of online mathematics, and the integration of computational thinking into the mathematics curriculum. Curriculum Vitae RECENT PUBLICATIONS Postelnicu, V.
