With an impetus towards science reform in the United States, citizen science is emerging as a platform with the potential to transform student learning and engagement. While current citizen science studies predominantly focus on student outcomes, there is little empirical evidence that captures the voices of teachers who voluntarily implement…

The three articles in this dissertation explore how curriculum, instruction, and assessments should align with the vision for science learning outlined in the Framework for K-12 Science Education. Together, the papers demonstrate how curriculum, instruction, and assessment, when mutually supportive of each other, can foster a learning environment…

The release of NGSS in 2013 brought forth uncertainty among K-12 educators on how to translate these standards into practical science lessons (Harris et al., 2017). One important instructional change that teachers still need assistance with is supporting sensemaking. To guide students in the process of sensemaking, teachers must ask questions that…

Educational reform in the United States is often focused on upgrading school curricula in response to evolution in science, technology, and society. Wyoming is no exception. A 2001 Wyoming Supreme Court decision granted constitutional protection to every K-12 student in the state for a "fair, complete, and equal education, appropriate for the…

This dissertation aims to address frequent calls for partnerships between informal science learning spaces and formal K-12 science education (e.g. Bevan & Dillon, 2010; Hofstein & Rosenfeld, 1996; NRC, 2009; Stocklmayer et al., 2010) as well as how informal educators and organizations are or are not addressing issues of equity within these…

In 2013, a new set of science standards was introduced for K-12 science education, called the Next Generation Science Standards (NGSS), which focused on three dimensions of science learning that work together: disciplinary core ideas, crosscutting concepts, and science and engineering practices. These standards are novel in their emphasis on…

Teaching science concepts for conceptual understanding has its challenges. Promoting conceptual change in the science classroom can be difficult because most concepts are complicated and counter-intuitive. This dissertation research aimed to determine the effect of teaching for conceptual understanding models on pre-service teachers' conceptual…

With growth in STEM postsecondary programs and careers positioned as a national priority, ensuring that K-12 science classrooms are staffed with highly qualified teachers is an important step towards building student interest in STEM and preparing students for STEM careers. However, previous studies of out-of-field teaching have indicated that…

The complicated history of the education of Native American children through U.S. government-sponsored practices has led to the elimination of the Native children's sense of Indian identity, culture, and language (Noel, 2002). In addition, increased emphasis on standardization and high-stakes accountability under the No Child Left Behind Act of…

The "Computer Science for All" (CS for All) movement launched in 2016, following a decade of increasing support for broadening access to computer science education in K-12. In the years since, it has grown into a broad-based effort to equip all students with the skills they need to thrive in a digital society. CS for All follows a long…

The field of computer science education currently lacks consistency in access, equity, and inclusion for students in historically marginalized groups, particularly students with disabilities. At the same time, research demonstrates a need for high-quality teacher professional development to support the inclusion of students with disabilities in…

Teachers face many barriers to climate change education, including access to resources. The U.S. national parks are an informal education sector that offers a variety of climate change educational resources (CCER). However, there are gaps in understanding teachers' use of these resources. This explanatory sequential mixed-method study aimed to…

This study's purpose was to explore science engagement and in/equity through science educators' narratives of servant leadership at both the K-12 and higher education levels in the United States. The research question was: "How have participants become and led others to become engaged in science?" I took an arts-based approach using…

The purpose of this study was to explore the perceptions of urban secondary math and science teachers, administrators, and district personnel regarding the factors that influence secondary math and science teachers with more than five years of teaching experience to remain in urban Title I districts. The participants were interviewed to gain their…

Computer science impacts our lives every day in a multitude of ways. Despite its ubiquity and power to shape the world, the computer science education community continues to struggle with issues of equity. Problems of access, opportunity, influence and achievement are pervasive and while a handful of scholars have investigated specific approaches…
