Public science events (PSEs) are an increasingly popular mode of informal science engagement. The burgeoning research on PSEs suggests a number of important benefits for visitors to these events, including increased scientific knowledge, improved attitudes toward science, and an increased awareness of science in everyday life. However, these…

This dissertation explores the role of classroom culture in shaping equitable student experiences and outcomes in science education, and examines how curricular structures might further reinforce equity. Here, equity in science education means supporting student identification, belonging, "and" learning in science, with particular…

Citizen Science is emerging as an innovative strategy to engage K-12 students in authentic science practices and relevant, real world phenomena. Citizen science is traditionally an informal science experience, with members of the public choosing to participate in the scientific research process through contributing data or other related efforts.…

Science classrooms often marginalize students of color, particularly Black and Brown boys, by devaluing their perspectives and supporting narratives that reinforce long-lasting deficit mindsets that sustain practices that keep Black and Brown boys in the margins. Using a Critical Participatory Action Research methodology, this qualitative research…

At the beginning of the COVID-19 pandemic, in March of 2020, education in the United States changed dramatically. Science teachers began to look at the implementation of ambitious and equitable science teaching practices differently. Employing the hermeneutic phenomenological framework, the purpose of this study was to investigate the lived…

Equity in science education is a central goal for many educators, researchers, policymakers, learning institutions, community organizations, and more. Scholars are increasingly looking to critical, intersectional, transdisciplinary, and dialectical theories to better understand the tensions that promote or limit equitable science education…

Student performance in high school Earth science coursework is an important factor in lifelong scientific literacy and workforce readiness in geoscience fields. Performance often depends upon access to high quality teaching and resources in precollege academic settings. This study employed a non-experimental, correlational research design to…

Schools across the United States are seeing an increase in culturally and linguistically diverse students. While there is recognition of the need for culturally and linguistically responsive teaching practices in K-12 settings, many teachers encounter challenges in effectively implementing these practices, particularly in science classrooms. There…

This dissertation study uses an alternative dissertation format to deliver two separate but interrelated studies. As a whole, the dissertation is connected by a single overarching research question: "What are the characteristics of effective, meaningful, and equitable science instruction through modeling and how do teachers' pedagogical…

This action research study, set in a midwestern high school in the United States, was designed to investigate the impact of implementing equitable grading practices in a first semester ninth-grade biology course. Many grading practices commonly used in classrooms in the United States are subjective, can be used to maintain compliance in the…

This dissertation examines two key axes of inequality in higher education -- gender and socioeconomic status (SES) -- in terms of differences in college persistence and college major using the nationally-representative High School Longitudinal Study of 2009. While gender differences in terms of STEM majors has been oft-studied, this dissertation…

Classrooms today are more ethnically and linguistically diverse. Unfortunately, students of color demonstrate a history of marginalized educational inequities (Williamson et al., 2007). These marginalized educational inequities impact academic achievement across all content areas especially literacy, math, and science. To improve the academic…

As researchers strive to work toward equity in education, attention to how teachers and teacher educators develop asset-based perspectives and what role power plays in this process has become a focus in teacher education (Carter Andrews et al., 2019; Philip, 2019; Souto-Manning & Martell, 2019). Within science teacher education, researchers…

Professional learning communities (PLCs) involve a process of collaboration, focus on student data and best instructional practices, and serve as a way for all students can receive an equitable education. Many schools implementing PLCs considered the term a noun, not a verb, leading to an inequitable education for high school students across…

The problem of practice explored in this work was the equitable education of students with disabilities (SWD) in high school science classrooms. This problem was first identified at Hartland High School in New Jersey, where through informal interviews science teachers reported being unprepared to teach SWD. This problem was then investigated…
