Fractions are foundational for success in algebra and STEM, but they are notoriously difficult for students. In past work, two separate branches of research from psychology and math education have studied fractions knowledge using different, isolated approaches. In this dissertation, I synthesize research from both fields about proportional…

Recent studies suggest that benefiting early from both a cochlear implant (CI) and exposure to cued speech (CS, support system for the perception of oral language) positively impacts deaf children's speech perception, speech intelligibility, and reading. This study aims to show how: 1/CS-based speech perception ("cue reading"), and…

Background or Context: Dual language education aims to foster the development of bilingualism, biliteracy, sociocultural competence, and academic skills in all school subjects. Early correlational research suggests that participation in dual language education is associated with higher achievement. Recent studies leveraged more comprehensive sets…

Theoretical perspectives within disciplinary fields are often characterized by initially dichotomous frameworks that become more integrative over time. Indeed, popular discourse on the Science of Reading emphasizes dichotomous contributions of word reading and language comprehension to reading. Yet, these skill sets are inherently complex,…

Background: Phonological processing skills have been found to contribute to spelling development across different orthographies; however, less is known about the role of orthographic knowledge. This longitudinal study explores the contribution of phonological and orthographic knowledge to spelling development in a semi-transparent orthography…

Gender stereotypes about science, technology, engineering, and math (STEM) are salient for children and adolescents and contribute to achievement-related disparities and inequalities in STEM participation. However, few studies have used a longitudinal design to examine changes in gender stereotypes across a range of STEM fields. In a large,…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

When student achievement is assessed, we seek to elicit a student's maximum performance -- a goal requiring the assumption that the student is fully engaged. Otherwise, to the extent that disengagement occurs, test performance is likely to suffer. Effectively managing test-taking disengagement requires an understanding of the testing conditions…

Chilean data show that a large reading-proficiency gap exists between students with high and low socioeconomic status (SES), that most children do not see themselves as readers, and that half of adolescents read below grade level (Agencia de Calidad de la Educacion, 2019; Consejo Nacional de la Cultura y las Artes, 2014). To understand the reasons…

This is the technical index for the research brief "Education's Long COVID: 2022-23 Achievement Data Reveal Stalled Progress toward Pandemic Recovery." Using data from 6.7 million U.S. public school students currently in grades 3-8, the study examined academic gains in the 2022-23 school year relative to pre-pandemic years. It also…

The purpose of this study is to examine the motivation type preferences of students in kindergartens and second, fourth, sixth, and eighth grades and the underlying reasons thereof after successfully completing a mathematics task. The students in the study solved an easy mathematics question. After they solved the problem, they were presented with…

Growing evidence suggests that contrary to popular belief, schools mostly do not generate achievement gaps in cognitive skills but, rather, reflect the inequalities that already exist. In the case of socioeconomic status, exposure to school often reduces gaps. Surprisingly little is known, however, about whether this pattern extends to gender gaps…

The impact of the COVID-19 pandemic continues to overwhelm the functioning and outcomes of educational systems throughout the nation. The public education system is under particular scrutiny given that students, families, and educators are under considerable stress to maintain academic progress. Since the beginning of the crisis, school-systems…

It has been common knowledge for decades that poor and working-class students tend to experience "summer learning loss," a drop in performance between spring and fall that serves to widen the gap between students. However, new research shows that the reality of summer learning loss is more complex. Megan Kuhfeld draws on data from the…

The purpose of this study was to determine the impact a sustained rotational blended learning model on the academic achievement on Title I K-8 elementary school students at a Catholic school in the areas of reading comprehension and mathematics as measured with standardized assessments, the Iowa Test of Basic Skills. In response to the first…
