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…

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…

This mixed methods study explored how elementary teachers reported using a commercially published instructional unit to plan and deliver science instruction in their elementary classrooms. Of particular focus is what elements of the program teachers eliminated during planning and instruction, what outside materials teachers added to instruction,…

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…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

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…

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 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…

There has been a growing emphasis on integrating green and sustainable chemistry (GSC) into the curriculum. Unfortunately, there is yet to be a nationwide, uniform decision of which aspects should be included or how, leaving individual instructors or institutions to decide whether--and how--to address GSC knowledge. Furthermore, faculty nationwide…

Efforts to understand changes in teacher curricula following the adoption of reform-based standards, such as the "Next Generation Science Standards" (NGSS) remain incomplete and prior scholarship has identified several topics in the standards (e.g., nuclear chemistry and kinetics) that remain infrequently addressed in teachers'…

This study was an action research self-study that examined my role as a teacher educator supporting a resident teacher in learning how to design inquiry-based culturally responsive science lessons. I explored my own growth in understanding how to act as a teacher educator to provide appropriately scaffolded support to promote learning for a…

This dissertation explores the role of classroom culture in shaping equitable student experiences and outcomes in science education, and examines how curricular structures might further reinforce equity. Here, equity in science education means supporting student identification, belonging, "and" learning in science, with particular…

The study aimed to investigate how the knowledge, understanding and skills of secondary science teachers in SC relate to their capacity to deliberately integrate World Class Skills (WCS) into their science classroom instruction through effective planning and pedagogical choices. The study employs the Partnership for 21 Century Learning framework…

Science education literature calls for students' participation in science practices through ongoing collective sensemaking built on coherence from the student perspective. However, few studies systematically consider students' point of view and there is little guidance for how teachers can lead the class to co-construct specified learning goals…

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…
