The purpose of this project is to test the sustained efficacy of Reading Recovery, an intensive one-on-one reading instruction program for the lowest-achieving first grade students, on state test scores in third and fourth grade. Many first grade students struggle with reading and for some of these students, low literacy achievement in first grade can set them up for continued difficulty in literacy throughout elementary school and beyond. The Reading Recovery program is based on the idea th...

Despite a lack of scientifically based research, credit-based transition programs such as International Baccalaureate (IB), Advanced Placement (AP), and dual enrollment programs in which high school students earn both high school and college-level credit for taking a college level course have become very popular as a means to increase the rigor of high school course offerings and improve the curricular alignment between high school and college. The purpose of this research is to examine the ...

This project will investigate the use of Moderated Nonlinear Factor Analysis (MNLFA) as a potential improvement upon existing vertical scaling methods that use the common item, nonequivalent group (CING) design. Vertical scales aim to capture growth across time by linking test forms appropriate for students of different ages, placing scores onto a common scale. This scale design is integral to several applications in education, ranging from the measurement of individual students' growth acro...

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 ...
