The threat of climate change makes it increasingly important for biologists and the public to understand how organisms respond to temperature. The Metabolic Theory of Ecology (MTE) predicts that temperature should affect organism performance, with implications for species interactions and ecosystems that span disciplines including mathematics,…

This study examines the impact of hands-on chemistry laboratories in shaping secondary students' chemistry self-concepts. Utilizing a mixed methods approach, the research sought to address how students' chemistry self-concept varied during the first semester of an introductory chemistry course and give voice to students' understanding of the role…

The recent Next Generation Science Standards recommend students have increased opportunities engaging in modeling work scientists do. Science classroom tasks include simple inquiry compared to more complex authentic inquiry that closely resembles authentic science. Science fair participation presents students with the opportunity to engage in…

STEM is a well-known acronym describing the intersections of science, technology, engineering, and math. Emerging from this paradigm is a relatively new interdisciplinary model entitled STEAM. STEAM endeavors to intersperse "the arts" into the sciences with the expectation of increasing student engagement and skills within the sciences.…

Computer-based learning environments (CBLEs) have emerged as powerful tools to support K-12 science learning. The Gas Laws simulation, an interactive, online CBLE, has been empirically demonstrated to support high-school students' understanding of particle theory, generally. However, a sub-analysis of existing data suggested certain embedded…

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…

Transition metals play an important role in many biological processes, however, they are also toxic at high concentrations. Therefore, the uptake and efflux of these metals must be tightly regulated by the cell. Bacteria have evolved a variety of pathways and regulatory systems to monitor the presence and concentration of metals in the cellular…

This study investigated whether or not lab type, traditional lab or virtual lab, influenced students' engagement. To measure student engagement six students were videoed over the course of an 18-week semester while conducting 10 lab experiments. To analyze student engagement, a systematic visual comparison in the tradition of single case research…

The development of scientifically literate citizens begins in the elementary school. Yet elementary school teachers are ill prepared to teach science (Trygstad, Smith, Banilower, Nelson, & Horizon Research, Inc., 2013). The research base on teacher preparation finds that programs designed to prepare elementary teachers are inadequate in…

Virtual worlds are well-suited for building virtual laboratories for educational purposes to complement hands-on physical laboratories. However, educators may face technical challenges because developing virtual worlds requires skills in programming and 3D design. Current virtual world building tools are developed for users who have programming…

This dissertation presents the results of an experiment that measured the learning outcomes associated with three different pedagogical approaches to introductory physics labs. These three pedagogical approaches presented students with the same apparatus and covered the same physics content, but used different lab manuals to guide students through…

Students' learning in inquiry-based investigations has drawn considerable attention of the science education community. Inquiry activities can be viewed as knowledge construction processes in which students are expected to develop conceptual understanding and critical thinking abilities. Our study aimed to explore the effect of experiments…

For this study, a research-based lab module was implemented in two high school chemistry classes for the purpose of examining classroom dynamics throughout the process of students completing the module. A research-based lab module developed for use in undergraduate laboratories by the Center for Authentic Science Practice in Education (CASPiE) was…

Chapter 1: The role of cell division in protein expression is important to understand in order to guide the development of better nonviral gene delivery materials that can transport DNA to the nucleus with high efficiency for a variety of cell types, particularly when nondividing cells are targets of gene therapy. We evaluated the relationship…

This study investigated whether the level of instructional guidance affected student learning and science self-efficacy when nine- and ten- year old children learn to design unconfounded experiments using control of variable strategies (CVS). Specifically, the goal of this study was to replicate and extend prior research that examines the impact…
