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…

Integrating science and engineering has become a focal point for current research in science and STEM educational fields. Infusing engineering design as an application of scientific principles is beneficial, as it demonstrates an authentic, real-world application and allows for not only student engagement and enthusiasm, but also an avenue to…

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…

Spatio-temporal processes are ubiquitous and prevalent across disciplines. Understanding the mechanisms underlying processes and integrating this information into models is of great interest, as it can improve forecasting accuracy and align with scientific motivation. Examples of such models include Partial Differential Equation (PDE) Models 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 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…

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…

Changing student conceptions in physics is a difficult process and has been a topic of research for many years. The purpose of this study was to understand what prompted students to change or not change their incorrect conceptions of Newtons Second or Third Laws in response to an intervention, Interactive Video Vignettes (IVVs), designed to…

The purpose of this Executive Position Paper project was to develop educational resources to support the teaching of nature of science topics to undergraduate students at Delaware Technical Community College. The investigation was driven by two exploratory projects and a review of the literature. The first exploratory project examined the…

In the last twenty years in US science education, professional development has emphasized the need to change science instruction from a direct instruction model to a more participatory and constructivist learning model. The result of these reform efforts has seen an increase in science education professional development that is focused on…

Teachers' beliefs shape their daily instruction and the materials presented to students. The personal views of educators are especially relevant when socioscientific issues are involved. Preservice and novice teachers' mastery of the nature of science (NOS) and personal beliefs in and out of the classroom influence their worldviews and classroom…

This mixed method study was aimed at examining the influence of dual processing (Type 1 and Type 2 thinking) on the development of high school students' nature of science (NOS) views. Type 1 thinking is intuitive, experiential, and heuristic. Type 2 thinking is rational, analytical, and explicit. Three research questions were asked: (1) Do the…

Developing K-12 science teachers' understandings of nature of science (NOS) and scientific inquiry (SI) continues to be a major goal of science education reform. There is consensus among science teacher educators that developing students' NOS and SI understandings is vital to the development of a scientifically literate citizenry. However, two…
