Abi Leaf has over 20 years of experience in mathematics education. She was a secondary mathematics teacher in EUHSD for 10 years, and prior to that a graduate teaching assistant at SFSU. In her role as content specialist for EUHSD, she has led her district in a system-wide effort to change the mathematics experience of high school students. These efforts include detracking the mathematics program, adopting an integrated mathematics program and organizing and providing professional development to teachers and administrators in support of these efforts. Abi currently sits on the Board of Directors for San Diego Math for America and is an adjunct lecturer in the School of Leadership Sciences of the University of San Diego, teaching Math Methods courses, as well as a variety of courses in their STEAM master’s and certificate programs. Her district’s work has recently been highlighted as a case study by NCTM in support of their recent publication, Catalyzing Change. Her research interests include systems-wide change efforts for improving equitable outcomes in mathematics for underserved populations of students.
