Our project explores simulations focused on eliciting and interpreting elementary students’ mathematics thinking provide preservice teachers with formative assessment opportunities. They have been used with preservice teacher educators and their students three partner programs, and administered for data collection in fourteen other programs. Our studies (1) examine how feedback from the simulations strengthens preservice teachers' abilities to elicit and interpret student thinking, and (2) establish the reliability and validity of the simulations as assessment tools.

Despite its importance, there is little research on children's use of and reasoning with different approaches to multiply or divide multi-digit numbers.

The project engages math teachers in lesson study to design and implement design-based lessons to teach geometry concepts.

This project contributes to advancing knowledge on STEM education focusing on societal challenges by harnessing the convergence of STEM subjects, including data science and computer science, to empower all students, especially multilingual learners (MLs). The research seeks to make two significant contributions. First, the project will develop a conceptual framework for multi-disciplinary STEM education with MLs to address pressing societal challenges. Second, the project will translate this conceptual framework into practical implementation in classrooms.

This project investigated the development of middle-school students’ understandings and practices of modeling in the context of investigations of variability and change in ecosystems. The project studied how and to what extent students’ participation in distinct forms of modeling informs their classroom-based citizen science investigations.

The Learning to Build on MOSTs project is focused on developing secondary mathematics teachers’ ability to enact the teaching practice of building on MOSTs. Previously, we conceptualized high-leverage instances of student mathematical thinking that emerge during whole-class interactions—instances we call Mathematical Opportunities in Student Thinking (MOSTs). We subsequently studied the practice of building that allows one to productively use MOSTs. In this study we investigate how teachers develop the practice of building on MOSTs.

The study investigates teachers’ use of mathematics language routines and a professional development model to support teachers’ learning. In particular, we examine teachers' opportunities for reflective practices within a Studio Day Cycle, looking at mathematics teachers’ development of adaptive expertise of mathematics instruction for multilingual learners.
