The first is uncovering knowledge about how people learn chemical ideas and how to facilitate that learning. The second is supporting the growth of emerging scholars as coinvestigators in chemistry and chemistry education. The third is recognizing that the knowledge gained and the people developed will seed future advancements for the chemistry enterprise by strengthening how chemistry is taught and learned.” What Yezierski's colleagues say: “Ellen is widely considered to be the premiere scholar on the professional development of high school chemistry teachers in the US. Her research has directly impacted the classroom pedagogy of more than 6,907 chemistry teachers around the globe and, by direct extension, the learning of their students.”—Stacey Lowery Bretz, Ohio Northern University Sponsor: Endowed fund established by Rohm and Haas Citation: For the design of an environmentally
