I have worked at Washington International school since August 2008, first as Director of Studies and now as Director of the Professional Development Collaborative, which supports professional learning at WIS and across the DC region. You can learn more about what we do at www.pdcollaborative.org. I have been affiliated with Project Zero, a research group at Harvard University's Graduate School of Education, for nearly 20 years, serving as Education Coordinator of the annual Project Zero Classroom summer institute at Harvard for 11 years and as founding Education Chair of the off-site Project Zero Perspectives conferences for seven years. I've been a secondary English teacher most of my career, working in U.S. public schools and international schools in Belgium. I am particularly interested in ways to foster thinking that can lead to deeper understanding, and in effective strategies methods for internationalizing school curriculum and practices. I hold a B.A. degree in English from Davidson College, and M.Ed. and Ed.D. degrees from George Washington University, where I often guest lecture in courses on curriculum and instruction and international education.
