The achievement gaps between Black and white students in math and science have remained unchanged over the last decade. Additionally, disparities in academic achievement and academic outcomes, like dropout, have persisted across genders. Existing research has explored the intricacies of various forms of identity -- namely racial and gender…

We use data from the Stanford Education Data Archive to describe district-level trends in average academic achievement between 2009 and 2019. Though on average school districts' test scores improved very modestly (by about 0.001 SDs/year), there is significant variation among districts. Moreover, we find that average test score disparities between…

Background: This empirical study aims to investigate the association between mathematics self-efficacy and mathematics achievement gaps among students in Grades 4, 8, and 12, utilizing data from the 2019 National Assessment of Educational Progress (NAEP). The study also considers student-level (e.g., mathematics self-efficacy, gender,…

This dissertation researched the scope of mathematics achievement disparities in the United States and how these disparities can be minimized through a self-efficacy lens. To answer pertinent research questions with data from the National Assessment of Educational Progress (NAEP) 2019 mathematics assessment in Grades 4, 8, and 12, gap analyses,…

Students' level of academic skills at school entry are a strong predictor of later academic success, and focusing on improving these skills during the preschool years has been a priority during the past 10 years. Evidence from two prior nationally representative studies indicated that incoming kindergarteners' math and literacy skills were higher…

The Expert-based Collective Advising Mechanism (ECAM) was embedded in the open online tutoring project to provide free tutoring for rural students and to help them improve their academic performance, and thus, to solve education inequity. Taking urban and rural students in Tongzhou District of Beijing as the objects, this study gathered data on…

Studies of gender disparities in STEM (science, technology, engineering, and mathematics) performance have generally focused on average differences. However, the extremes could also be important because disparities at the top may shape stratification in access to STEM careers, while disparities at the bottom can shape stratification in dropout.…

Students' level of academic skills at school entry are a strong predictor of later academic success, and focusing on improving these skills during the preschool years has been a priority during the past ten years. Evidence from two prior nationally representative studies indicated that incoming kindergarteners' math and literacy skills were higher…

Recent evidence demonstrates that disparities by race/ethnicity and socioeconomic status in science achievement are present in the earliest grades of school. Preschool represents one potential policy solution; however, little research has explored the relationship between preschool attendance and science outcomes. This study examines whether…

Today's economy demands higher order thinking skills (HOTS), and the public education system has a critical role in supporting students' acquisition of HOTS. Yet, numerous studies documented inequity in access to higher quality instruction that promotes HOTS, which could result in wide test score gaps in HOTS. In this study, I examined test score…

I brought together two strands of literature, one investigating the moderate but persistent underachievement of girls in mathematics in most countries, and the other examining the role of self-efficacy and other self-beliefs in predicting behaviour and achievement. I implemented detailed decompositions of the gender mathematics gap, both at the…

This study utilizes the 2015 data from the Hong Kong sample of the Program for International Student Assessment to examine the relative importance of various factors on the science learning performance of Hong Kong students. Using hierarchical linear modeling (HLM), we examined the effect of students' affective characteristics, involvement, and…

Empirical results are consistent with the hypothesis that socioeconomic factors contribute to initial disparities in performance that are perpetuated by demoralizing grading, testing, and grouping practices throughout the K-12 years. The hypothesis may explain why the achievement gap increases after children enter the school system, why Black…

Information frictions significantly shape students' academic trajectories, but their differential impact across student backgrounds remains understudied. Using a novel panel survey capturing incoming students' subjective expectations and anonymized transcript data from Arizona State University, we first show that parental education strongly…

We analyzed data from a large-scale (N = 39,213), longitudinal study of urban students to assess child factors (gender, ethnicity, English language learner status, school readiness skills, type of pre-K attended, early elementary school academic performance) prospectively associated with eventual gifted identification in elementary school.…
