Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

In this dissertation, I examine how two major social programs in Kentucky--state-funded preK and Family Resource and Youth Service Centers--impact children's outcomes across the state, including racial, ethnic, and economic equity through elementary school. In each chapter, I will analyze how early childhood opportunities relate to outcomes…

The Austin Independent School District (AISD) offered several academic summer programs to students June through August 2021. These programs offered students opportunities to accelerate their learning, recover academic course credits, and support grade level transition. Although AISD offered a variety of summer programs in 2021, this report focuses…

This report demonstrates the effects of the Arkansas Better Chance program (ABC) on late elementary outcomes (third through sixth grades). End of year assessments, which varied over the course of the study years, were examined for students of three preschool cohorts. Students included in the statewide study received free lunch all years and were…

Although some research-based educational practices have shown promise, many fail to be implemented at a scale that affects more than a small proportion of children. Further, research on interventions for young children includes mixed results, with most documenting "fadeout" of effects after several years, but some showing lasting…

This study hypothesized that HISD prekindergarten participation consistently correlated with better educational outcomes for students. Taking into account students' age differences through kindergarten enrollment, propensity score matching controlled for students' background characteristics. Three cohorts of students in this study were eligible or…
