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 US Bureau of Labor Statistics projects that jobs within the life and physical sciences will grow by 8% between 2020 and 2030; therefore, it is imperative that students receive an engaging, rigorous, and comprehensive science education. Many urban and minority students have been denied this opportunity as evidenced by their poor performance on…

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…

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…

The three articles in this dissertation explore how curriculum, instruction, and assessments should align with the vision for science learning outlined in the Framework for K-12 Science Education. Together, the papers demonstrate how curriculum, instruction, and assessment, when mutually supportive of each other, can foster a learning environment…

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…

This study thoroughly explores the relationships between the challenges faced by students and the alternative problem-solving strategies employed. By analyzing these connections, the research aims to offer a comprehensive understanding of how students address difficulties in science learning and the adaptive strategies they apply. Through this…

Professional development programs aim to make long-lasting change to teacher practice. However, these programs are often short-lived due to limited personnel, cost, and time constraints. Using an actor-oriented approach, this study aimed to understand how teachers transfer their learning from a professional development program focused on…

This action research study aimed to find ways to adjust my practice by incorporating inquiry-based, science activities and virtual simulations to improve student conceptual understanding of physical and chemical changes. A multi-lesson, curricular intervention combining inquiry-based activities and virtual simulations was developed using…

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…

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 study was to conduct a critical text analysis of Next Generation Science Standards (NGSS) policy documents and the resources teachers have access to help them implement these standards into their classroom. NGSS outlines the skills and content needed for students to become proficient in STEM fields. These standards increase the…

This study examines the opportunities presented to high school chemistry students through argument driven inquiry (ADI) and how these opportunities led to changes in student understanding. Lesson plans and videos were analyzed to determine how much time students spent arguing from evidence including constructing and argument board, discussing with…

With school populations across the country becoming increasingly representative of students from diverse cultural and linguistic backgrounds, new considerations must be made to promote equitable and engaged science learning for all students (National Academy of Science, National Academy of Engineering, & Institute of Medicine [NAEEM], 2011).…
