The purpose of this mixed-method action research study was to improve Black students' performance in my sixth-grade science class by improving their ability to use the claim, evidence, and reasoning (CER) framework. Using criterion-based convenient sampling, I enlisted 17 Black participants, all of whom were underperforming in my science class at…

This study aims to discover the existing experiences that lead to local rural knowledge (LRK) of specific rural Northeast Nebraska communities. This information will assist in understanding the impact that LRK has on young children's science knowledge in rural communities. By engaging in hands-on experiences and interactions, science learning…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

The Next Generation Science Standards (NGSS) demand that science educators shift from traditional to NGSS teaching and learning. The purpose of this qualitative case study was to explore the change process of shifting from traditional one-dimensional teaching to NGSS three-dimensional teaching and learning. A survey was sent to all science…

A growing body of literature focusing on undergraduate biology education calls for students to engage in the ways of thinking, feeling, and doing that reflect those in which biologists engage. Such reform efforts suggest that learning is best fostered when students engage in practices, concepts, and scientific reasoning as they endeavor to explain…

Educators have struggled with maintaining student engagement in science, especially as students transition from primary to middle school and upper grades (Vedder-Weiss & Fortus, 2012). A recent push in science education has been the adoption of the Next Generation Science Standards (NGSS), released in 2013, whose development was guided by…

Science centers, despite their growing popularity (Association of Science and Technology Centers [ASTC], 2022), have diversity, equity, and inclusion (DEI) concerns (Garibay & Olson, 2020) that threaten the achievement of their mission (Feinstein & Meshoulam, 2014) and the very utility of their existence (Ash 2022; Dawson, 2019). The…

Undergraduate general chemistry courses are often perceived in a negative light by students. Student attitudes towards chemistry play a significant role in their success in chemistry and retention in STEM altogether. Research has shown in K-12 classrooms that care-based instruction strategies can help to improve student attitudes towards…

Pre-service science teachers develop their teaching practices within and across the university and school contexts of their teacher education programs. The practices and visions of teaching and learning emphasized in each context are often disjointed, a problem referred to as the "two-worlds pitfall." Responding to the call for teacher…

This dissertation examined the relationship between elementary school science teachers' epistemic orientation and classroom learning environment type--generative or replicative--they established for science knowledge development. Drawing on the theory of epistemological development and understanding, the influence of teacher epistemic beliefs on…

This study aimed to explore Cooperative Learning theories and practice by examining the relationships among three aspects: Experience, Practice and Perceptions. The data were from interview records from eight science teachers. As a student-centered active pedagogical trend, cooperative learning has become part of one of the most effective and…

This dissertation focused on the outcome of elementary science teachers' learning in theories and practices of epistemic tools in professional workshops over the course of two years, starting in the summer of 2019. Study one focuses on teachers' understanding of language as an epistemic tool. The data were teachers' written responses to a…

In this study, I documented, analyzed, and compared the thought processes of six high school science teachers during twenty minutes of planning for NGSS-aligned instruction. Teachers' thoughts were captured using a virtual revisit think-aloud protocol and their thoughts were analyzed and compared using a novel tool called a thinking web. A…

Developing scientific literacy, which involves applying scientific knowledge to solve real-world problems, is a primary goal in science education. Socioscientific Issue (SSI) provides students opportunities to reason through authentic and complex scientific dilemmas that reflect real-world issues, thus fostering a deeper understanding of…
