## Ana Stephens

### Associate Researcher

Ana Stephens is an Associate Researcher at the Wisconsin Center for Education Research. Her research concerns the development of algebraic thinking in the elementary grades.

She currently works on LEAP (Learning through an Early Algebra Progression), a series of projects devoted to identifying a framework of early algebraic concepts and practices that can be taught in the elementary grades, testing the efficacy of an instructional sequence built from this framework, and describing levels of sophistication observed in students’ work around particular algebraic concepts.

Her interests include studying the development of children’s mathematical thinking and supporting teachers to focus on student thinking in making instructional decisions.
