**Resource | Designing ‘Productive Uncertainty’ into Investigations to Support Meaningful Engagement in Science Practices**

We want students to engage from the earliest ages in science and engineering practices with sincere curiosity and purpose. Science investigations can be viewed as “working through uncertainty.” However, 3D instructional materials often try to support engagement in science practices by making them very explicit and scaffolding the process to make it easy to accomplish—arguably, too easy. An...

**Resource | “Approximate” Multiplicative Relationships between Quantitative Unknowns**

Three 18-session design experiments were conducted, each with 6–9 7th and 8th grade students, to investigate relationships between students’ rational number knowledge and algebraic reasoning. Students were to represent in drawings and equations two multiplicatively related unknown heights (e.g., one was 5 times another). Twelve of the 22 participating students operated with the second...

**Resource | Tiering Instruction for Middle School Students**

Differentiating instruction (DI) is a pedagogical approach to managing classroom diversity in which teachers proactively adapt curricula, teaching methods, and products of learning to address individual students' needs in an effort to maximize learning for all (Tomlinson, 2005). DI is rooted in formative assessment, positions teachers and students together as learners, and involves providing...

**Resource | Exploring Prospective Teachers’ Ability to Generate and Analyze Evidence-based Explanatory Arguments**

In this paper, using written responses of 37 PSTs preparing to teach grades 1-8 mathematics, we examined explanations they constructed to support their problem solutions and explanations they provided in support of their critiques of student-generated explanations. We also examined features of explanations on which PSTs drew in their critiques of mathematical explanations of students. Our results...

**Resource | Restoring Mathematics Identities of Black Learners: A Curricular Approach**

Black learners are subject to systemic physical, symbolic, and epistemological violence in mathematics classrooms. Such violence has negative ramifications for Black children’s mathematics learning and identity development. The authors argue that space should be made within the mathematics classroom to repair the harm caused by this violence. This article describes an identity-based curriculum,...

**Project | Pandemic Learning Loss in U.S. High Schools: A National Examination of Student Experiences**

As a result of the COVID-19 pandemic, schools across much of the U.S. have been closed since mid-March of 2020 and many students have been attempting to continue their education away from schools. Student experiences across the country are likely to be highly variable depending on a variety of factors at the individual, home, school, district, and state levels. This project will use two,...

**Project | Fostering Equitable Groupwork to Promote Conceptual Mathematics Learning**

This exploratory study involves a long-term partnership between the principal investigator (PI) and a middle school teacher and her students. Two major goals of the study are to describe how students learn to collaborate with one another over time to make sense of mathematics, and how students and their teacher negotiate what constitutes equitable collaboration, with African American students'...

**CAREER Spotlight | Cultivating Teachers’ Epistemic Empathy to Promote Responsive Teaching (NSF #1844453)**

This project aims to study and cultivate science and mathematics teachers’ “epistemic empathy”—their capacity for tuning into and valuing someone’s cognitive and emotional experiences in the process of constructing, communicating, and critiquing knowledge. The research will examine how such empathy influences teachers’ responsiveness and how it shapes students’ engagement.
