Cathy is Professor Emerita of Childhood Education, CCNY/CUNY, where she was the founding director of Mathematics in the City. In 2008 she left the university to establish New Perspectives on Learning and publish with her team Contexts for Learning Mathematics (CFLM), now a full core inquiry-based, hybrid, k-5 program. The company is also focused on professional development and system-wide change, offering professional development workshops and on-site consulting with schools around the world and at the company’s two workshop centers in the U.S. (in New London, CT and San Francisco, CA.) Over the last several years, the work has expanded with the establishment of two more companies: New Perspectives Online, an online platform form teacher learning, and New Perspectives on Assessment, a web-based app for formative assessment with teaching implications, aligned with the CCSS.  Cathy has been the senior content consultant for DreamBox Learning since its inception.
