As the adoption rate of the Next Generation Science Standards (NGSS) continues to rise in the United States, there is an increasing need for the development of high-quality instructional materials that reflect NGSS and effectively prepare teachers for its implementation. The NGSS aim to foster an understanding of three interconnected dimensions in…

Despite reform efforts and calls to accept science as a primary subject in elementary school curriculum and instruction (NRC 2007, 2012), science is still often neglected, deprioritized, minimally taught, or taught through traditional methods where teachers and textbooks are the gatekeepers of knowledge (Banilower, 2019; Banilower et al., 2018;…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

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…

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…

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…

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…

Zoos have been under attack by animal rights groups for decades. Despite significant reforms to improve animal welfare in accredited zoos and aquariums across North America, and significant participation in animal conservation efforts globally, these attacks persist. If zoos are to continue long-term, they need to establish themselves as community…

The purpose of this quantitative study was to evaluate the effectiveness of the LearnEd Notebook curriculum when used with two groups of eighth-grade African American male students in teaching science. More specifically, the researcher sought to determine if there was a correlation between the utilization of the LearnEd Notebook Science curriculum…

Next Generation Science Standards (NGSS) were developed by 26 lead states with NSTA, AAAS, NRC, and Achieve in 2013 to provide a new vision for the teaching of science in U.S. schools. Teachers' applications have been mainly concentrated on efforts to align the current practices with the standards. Elementary science teachers need to use…

This quasi-experimental study aimed to determine if there is a statistically significant difference in student test scores when a modified instructional sequence in middle school science is used versus the instructional sequence suggested by the Commonwealth of Virginia. The Grade 8 science cumulative Standards of Learning (SOL) test results from…
