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 is a qualitative, descriptive, and multi-case study, in which the researcher investigated the perceptions of middle school teachers who were implementing three-dimensional learning aligned with the Next Generation Science Standards (NGSS) into their instructional practices. The participants were 10 middle school teachers who worked in three…

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…

Recent K-12 science reforms necessitate a shift in curriculum and instruction to support coherence from the students' perspective. This coherence emerges when students see their science work as addressing and making progress on their questions and problems. Storyline curricular units afford student coherence, but teachers need support to craft…

To increase equity and inclusion for underserved and excluded Indigenous students, we must make efforts to mitigate the unique barriers they face. As their knowledge systems have been historically excluded and erased in Western science, we begin by reviewing the literature on the inclusion of Traditional Ecological Knowledge (TEK) in biology…

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 investigation of Science, Technology, Engineering, and Mathematics (STEM) and the quality of education within and between the four disciplines continues to be a topic of concern throughout the United States. Employers, policymakers and educators have recognized a need for a stronger focus on the quality of STEM education in schools (Becker…

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…

Since the launch of Sputnik by the U.S.S.R. on October 4, 1957, the United States has aimed to bolster nationwide STEM education with the intention of creating a strong STEM pipeline. Despite many efforts, there remains a distinct lack of diversity in the STEM career fields, and many people cannot accurately describe what engineers do. These two…

This study addresses the inadequacies of the traditional ninth-grade science curriculum at The Charter School of Wilmington (CSW) and proposes a focused initiative to enhance the curriculum's relevance and effectiveness. The current Integrated Science & Research curriculum lacks socioscientific inquiry, neglecting to incorporate social issues…

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…

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…
