Deborah Trumbull`s research and teaching interests are intertwined. As a science teacher educator, she is interested in studying new ways to help learners understand science and new ways to help novices become productive science teachers able to use new ways of teaching. Her current NSF-funded Noyce Scholars program allows her to follow up on the development of the department`s graduates teaching in high needs school districts in order to understand better how to prepare new teachers for working in these challenging settings. This work is supplemented by a new project that will look at new teachers, graduates of Cornell, who are working in contrasting districts to determine factors that limit or generate professional development.
