This project aims to develop a fraction sense intervention for middle school students with or at risk for mathematics difficulties. Many middle-school students struggle to develop a basic understanding of fractions. Fractions are not only foundational for learning algebra, but facility with fractions also affects daily life functioning (e.g., managing personal finances). Unfortunately, many students fail to develop these foundational skills, which can lead to negative educational, vocational...

The purpose of this project is to refine, extend, and validate a number sense screener for students from prekindergarten through Grade 1. Number sense-the knowledge of number, number relations, and number operations-is highly predictive of later math success and underlies many difficulties students have in mathematics. Being able to identify students who have difficulties with number sense early in development is critical to providing educational interventions that promote readiness and succ...

The purpose of the National Center on Mathematics Instruction for Students with Mathematics Difficulties is to increase knowledge of how children acquire and fail to acquire an understanding of rational numbers (i.e., fractions) and how children with math difficulties can be taught to understand and operate fluently with rational numbers. The new center will conduct exploratory research including both small-scale experimental and longitudinal studies to examine the cognitive processes, such ...

The purpose of this project is to examine the efficacy of the fraction sense intervention (FSI), developed with funding from an IES grant, on student mathematics performance to understand mediators and moderators of the effects on student outcomes. Competence with fractions is crucial for success in math as well as for many careers and vocations. Students who leave 6th grade without fundamental understandings of fractions may experience cascading difficulties that lead to lifelong avoidance ...
