This project uses a mixed-methods design to test the hypothesis that key approaches to high school reform grease the mathematics and science pipelines for all students in reforming high schools. This study is…
Paving the Way for Fractions: Identifying Foundational Concepts in First Grade (Collaborative Research: Newcombe)
Project
-
The goal of this project is to investigate the extent to which individual differences in informal fraction-related knowledge in first-grade children are associated with short- and longer-term fractions and math…
SPIRAL: Supporting Professional Inquiry and Re-Aligning Learning through a Structured e-Portfolio System
Project
-
This project would investigate a new model of professional development for teams of science teachers in grades K-8 who would create electronic portfolios documenting how they taught specific concepts about…
Project
-
The goal of this project is to develop learning progressions and assessment items targeting computational thinking. The items will be used for a test of college-ready critical reasoning skills and will be…
Project
-
This project will explore how children in grades K-2 understand visual representations of algebraic concepts. For instance, children might create tables or graphs to organize information about the relationship…
Project
-
The project continues and completes the development and refinement of an electronic Test of Early Numeracy (e-TEN) in English and Spanish, focused on number and operations for young learners. The assessment…

Acquiring scientific knowledge and skills requires persisting through challenges, yet it has become increasingly common for parents in the United States to step in and solve problems for their children. This…
Project
-
Effective “early” algebra interventions in elementary grades that can develop all students’ algebra readiness for later grades are needed. This study will use an experimental design to test the effectiveness of…
Project
-
This project is using data from interviews with 160 K-12 students and 20 adults to describe common understandings and progressions of development for negative number concepts and operations. The project is…
Project
-
This project will provide an empirically-supported learning progression for a key scientific practice, scientific modeling. The specific instructional materials created as part of the project can serve as a…

LOCUS (Levels of Conceptual Understanding in Statistics) is an NSF Funded DRK12 project (NSF#118618) focused on developing assessments of statistical understanding. These assessments will measure students’…
Designing an Integrated Framework for Genetics Education to Develop Innovative Curricula and Assessments
Project
-
This project is developing a model for integrating best practices in technology-supported instructional design and formative assessment for genetics instruction in upper elementary, middle and high school. Using…
Project

In this project researchers are implementing and studying a research-based curriculum that was designed to help children in grades 3-5 prepare for learning algebra at the middle school level. Researchers are…
CAREER: Fraction Activities and Assessments for Conceptual Teaching (FAACT) for Students with Learning Disabilities
Project
-
This project is documenting how students with learning disabilities (LD) access and advance their conceptual understanding of fractions. Rather than focusing on the knowledge students do not have,…
Project

This project tests and refines a hypothetical learning trajectory and corresponding assessments, based on the collective work of 50 years of research in mathematics education and psychology, for improving…
Project
-
Despite the tremendous growth in the availability of mathematics videos online, little research has investigated student learning from them. The goal of this exploratory project is to create, investigate, and…
Project
-
Most students learn about negative numbers long after they have learned about positive numbers, and they have little time or opportunity to build on their prior understanding by contrasting the two concepts. The…
