### Biography

Jeffrey E. Barrett is Professor of Mathematics Education and Associate Director of the Center for Mathematics, Science and Technology at Illinois State University.

### Current Courses

131.001Geometric Reasoning: Geometry As Earth Measures

131.001Geometric Reasoning: Geometry As Earth Measures

304.001Modern Geometry For Middle School Teachers

403.001Theories Of Mathematics Learning

### Teaching Interests & Areas

Since 1997, I have taught a variety of courses including content courses for non-majors, methods courses for undergraduate majors, courses designed for practicing teachers, and graduate courses for Ph.D. or Masters -level students. I am interested in teaching about cognition and measurement, as well as the content of geometric reasoning. I am also interested in teaching about the use of dynamic computer tools for pedagogy such as dynamic geometry software in K-12 schooling.

### Research Interests & Areas

Primary research interests include the learning and teaching of the mathematics of measurement, geometric reasoning, the use of computer software to model mathematical ideas, and the professional development of teachers engaged in teaching elementary and middle-school level mathematics or science. Dr. Barrett served as Principal Investigator of two NSF-funded projects: "Learning Trajectories to Support the Growth of Measurement Knowledge: Pre-K through Middle School" and "A Longitudinal Examination of Children’s Developing Knowledge of Measurement: Mathematical and Scientific Concept and Strategy Growth from Pre-K to Grade 5". Both projects were part of the Discovery Research K-12 Program of the National Science Foundation.
