Despite decades of research, NOS is still rarely explicitly and accurately taught in K-12 schools (Abd-El-Khalick & Lederman, 2023). Teachers often address NOS ineffectively as a result of inadequate knowledge of NOS and science content (Wahbeh & Abd-El-Khalick, 2014) as well as NOS pedagogy (Hanuscin et al., 2011). A variety of contextual…

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…

Scholars over the past few years have drawn attention to the enormous potential role historical stories can play in promoting student understanding of issues associated with the nature of science (NOS). Such stories, often referred to as "historical narratives," are thought to do so by providing a rich historical context within which…

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…

This study investigated how the figured world of the RET, and other figured worlds of science that teacher's experience, impacted their conceptions around the nature of science and their identities in science and as science teachers. The main premise behind RET programs is that by partnering science teachers with scientists as mentors, science…

The subject of chemistry is a cornerstone of high school science programs and a conceptual understanding of chemical equilibria and Le Chatelier's Principle continues to be both a fundamental and paradoxically difficult subject for educators and students. This study evaluated the effectiveness of a prototype immersive virtual reality environment.…

Competency levels around scientific literacy for high school students in the United States are insufficient for students' future ability to be competent consumers and voters. The purpose of this action research study was to explore how students were being exposed to scientific literacy concepts in high school science courses in the United States.…

This dissertation investigates inservice elementary teachers' nature of science (NOS) and nature of technology (NOT) implementation and development of NOS views. These investigations are done in three separate studies: views of NOS, implementation of NOS, and implementation of NOT. While the NOS is a necessary part of learning that should take…

The aim of this research is to determine what differences may exist in students' structural knowledge while using a variety of concept mapping assessments. A concept map can be used as an assessment which connects concepts in a knowledge domain. A single assessment may not be powerful enough to establish how students' new knowledge relates to…

At universities across the United States the epistemological beliefs of students have been observed to deteriorate after a semester of instruction in an introductory physics course. What this indicates is that after taking a course in physics most students, for example, may become less capable of delineating between evidence-based reasoning and…

Modern global society is complex and interconnected with infinite limitations and increasing competition for resources. Increasingly, people are aware of the impact of modern lifestyle choices on the sustainability of the planet. Sustainability is a growing focus of many world leaders, politicians, and educators. Many societal leaders agree that…

Previous to this study, teaching and learning practices in the first-grade classroom of study were primarily teacher and content driven and did not reflect the student-driven inquiry process. The identified problem of practice for this action research study was the first-grade students in the teacher-researcher classroom did not demonstrate…

Achieving widespread scientific literacy has been a longstanding goal of US science standards, requiring that students and teachers possess contemporary nature of science (NOS) conceptions. However, NOS conceptions are repeatedly found to be wide-ranging or 'naive', resulting in regular efforts by science education researchers to hone, or…

Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…

The adoption of the Next Generation Science Standards (NGSS) has brought with it a need for classroom assessments that measure students' ability to make sense of, explain, and use science, with many of the performance expectations asking students to apply scientific principles and evidence to produce an explanation. But creating coherent written…
