Before joining the Teacher Education Department at CSU East Bay, Julie supported mathematics teachers as a designer and provider of mathematics professional development for TeachingWorks, Math Solutions, and as an independent consultant. Julie is a former school teacher in the San Francisco Bay Area. Her graduate studies were in the Development in Mathematics and Science program at the University of California, Berkeley, where she earned a master’s degree and Ph.D. in mathematics education. Her research focuses on the teaching and learning of mathematics concepts that are foundational but considered “hard to teach and hard to learn.” Julie is also the author of Beyond Invert and Multiply: Making Sense of Fraction Computation, Grades 3-6, as well as the co-author of Beyond Pizzas and Pies: 10 Essential Strategies for Supporting Fraction Sense, Grades 3-5.
