Erik Jacobson is an Associate Professor of Mathematics ¾ÅÉ«ÊÓƵat Indiana University. His research focuses on how mathematics teachers develop knowledge and beliefs—including those related to equity and diversity—that support effective instruction. He was the recipient of an AERA Dissertation Award for a secondary analysis of TEDS-M data that revealed relationships between the type of early field experience in elementary teacher preparation programs and program outcomes including mathematics-related knowledge and beliefs. He currently directs an NSF-funded research project, Assessing the Structure of Knowledge in Teaching Mathematics. This project is developing a multidimensional assessment of pedagogical content knowledge for teaching fractions and decimals to investigate how knowledge, teaching practices, and student learning are reciprocally related at the grain-size of specific curriculum standards. A second ongoing research project, Mathematics Teachers' Beliefs and Practices, is examining how preservice teachers’ perceptions of student gender and race/ethnicity—and their beliefs about who is (or can be) mathematically brilliant—are related to instructional decisions. His work has been published in research journals including the Journal of Research for Mathematics ¾ÅÉ«ÊÓƵand the Journal of Mathematics Teacher ¾ÅÉ«ÊÓƵand in practitioner journals including Teaching Children Mathematics and the Mathematics Teacher.
