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…

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…

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,…

While achievement gaps have been widely studied, less attention has been given to how these gaps relate to students' patterns of "academic mobility"-- that is, how students' relative academic standing changes from early to later grades. Using rich administrative data from Washington state, we apply an academic mobility framework to…

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.…

There is very limited evidence globally of the impact that learning in an unfamiliar language has on girls' educational outcomes. In Rwanda, children learn in English medium instruction (EMI) classrooms throughout the basic education cycle, with a recent policy change removing Kinyarwanda as the medium of instruction for the first three years.…

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…

The purpose of this study is to develop tests for monitoring the number sense skills of primary school students based on proficiency definitions and to compare their number sense skills according to gender, school type, and mother's educational level. The first stage addressed to test development in which anchor items were used for vertical…

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…

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…

In the United States, women are more likely than men to enter and complete college, but they remain underrepresented among baccalaureates in science-related majors. We show that in a cohort of college entrants who graduated from high school in 2004, men were more than twice as likely as women to complete baccalaureate degrees in science,…

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…

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.…

Recent reforms in education call for science teachers to incorporate STEM concepts into their curricula. This study explores the association among student and teacher demographics, and student learning of engineering content and attitudes towards STEM after participation in an elementary or middle school engineering-based science curricula.…
