A confluence of circumstances in educational policy and teacher preparation have placed a low priority on elementary science teacher preparation. Historically, a lack of elementary science teachers' subject matter knowledge and pedagogical knowledge has negatively impacted science teaching self-efficacy, which is linked to many teacher and student…

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…

In response to the global crisis of type 2 diabetes prevalence, this dissertation investigated the impact of a culturally sustaining, health-centric science curriculum contextualized in type 2 diabetes. Using a case study methodology, it explored how the curriculum shaped math and science preservice teachers' (PSTs) perceptions of science and how…

Many stakeholders emphasize the importance of diverse populations' participation in the sciences, though the motivations for this vary. Some reference an economic standpoint by emphasizing the importance of either recruiting more science workers to compete in a global economy, or of individual financial success for people from historically…

Culturally Relevant Education (CRE) focuses on the design of curricular materials that strengthen students' cultural identities while teaching classroom content and science practices. While examples of CRE in science continue to grow, the identities and cultures of the designers are often different from those of the students and communities in…

Science education is shifting from a vision of students memorizing facts towards engaging in figuring out the natural world as students build ideas from their own experiences and backgrounds. This shift is hard for teachers. One way to support teachers is curriculum-based professional development, which pairs high-quality instructional materials…

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.…

The intersecting issues that this study addresses are the lack of engagement in civic opportunities for underserved youth and the environmental injustices that disproportionately impact marginalized populations. To address these issues, the purpose of this youth participatory action research (YPAR) investigated how a high school science teacher…

This dissertation investigates the concept of social justice within the context of chemistry teaching. Social justice science teaching has demonstrated positive impacts on students' engagement, self-efficacy, and affiliation with science across a range of ages and learning contexts, yet the often-flexible definition of the concept can make it…

The Next Generation Science Standards (NGSS) is the most recent reform in science education across the United States. The NGSS demands a shift in both teaching and learning. Yet there is no direction on how teachers are to implement this shift in their classrooms. This mixed-methods study examined 12 middle school teachers' perceptions and the…

Using a phenomenological methodology, a cohort of four experienced science teachers was interviewed about their experience transitioning from traditional, teacher and fact-centered science curricula to inquiry-based curricula. Each teacher participated in two interviews that focused on their teaching backgrounds, their experience teaching the…

As science becomes increasingly computationally intensive, the need for computational thinking (CT) and computer science (CS) practices in K-12 science education is becoming paramount. Incorporation of CT/CS practices in K-12 education can be seen in national standards and a variety of allied initiatives. One way to build capacity around an…

The purpose of this study was to investigate how school districts dealt with the challenges of implementing new science learning standards in their middle schools. Six Long Island school districts of varying size and levels of need, with different curricula models, and distinct building grade-level configurations were purposefully selected as case…

Designing professional development that effectively supports teachers in learning new and often challenging practices remains a dilemma for teacher educators. Within the context of current reform efforts in science education, such as the "Next Generation Science Standards," teacher educators are faced with managing the dilemma of how to…

The use of informal science education in rural areas, especially at rural middle schools has not been well documented. Although rural areas have accessible outdoor learning environments compared to urban areas, teachers are less likely to incorporate informal science activities. The purpose of this study was to evaluate two seventh grade life…
