Pam Grossman is Dean and the George and Diane Weiss Professor at the University of Pennsylvania’s Graduate School of Education. A distinguished scholar, she came to Penn from Stanford University’s School of Education, where she was the Nomellini-Olivier Professor of Education. At Stanford she founded and led the Center to Support Excellence in Teaching and established the Hollyhock Fellowship for early career teachers in underserved schools. Before joining Stanford, she was the Boeing Professor of Teacher Education at the University of Washington. Grossman studies teacher and professional education, teacher knowledge, and the teaching of English in secondary schools. Her widely cited articles have appeared in Teachers College Record, American Educational Research Journal, Educational Researcher, and Educational Evaluation and Policy Analysis, among others. Her most recent work considers the classroom practices of middle school English teachers that are associated with student achievement. As part of this research, she helped develop the Protocol for English Language Arts Teaching Observation (PLATO) instrument, which has been used in the Measures of Effective Teaching project. Her latest study, funded by the Institute of Education Sciences, examines a professional development model that uses PLATO as a tool for instructional improvement.
