Nicora Placa is an assistant professor at Hunter College. Previously, she taught elementary and middle school mathematics in New York City and conducts professional development for teachers both nationally and internationally.
Her current research is focused on exploring teacher learning, particularly urban K-8 mathematics teachers and teacher leaders. She is a co-PI on an NSF study titled “Taking a Deep Dive: Investigating PD impact on what teachers take up and use in their classroom.” She is also the author of a book on collaborative coaching that describes how school culture can be transformed through mathematics coaching practices that is scheduled to be released by Stenhouse in 2020.

My research focuses on how to foster the development of students’ mathematical practices in early grades. I am especially interested in how young students develop the ability to justify their mathematical reasoning and the role it plays in their conceptual understanding. In addition, my work explores teacher learning, particularly urban K-12 teachers of mathematics (pre-service and in-service) and teacher leaders.
