Understanding is widely touted to be of paramount importance for education. This is especially true in science education research and development where understanding is heralded as one of the cornerstones of reform. Teachers are expected to teach for understanding and students are expected to learn with understanding. This dissertation is an…

Scientists produce research resources that are useful to future research and innovative efforts. In a typical scientific scenario, the results created by a collaborative team often include numerous artifacts, observations and relationships relevant to research findings, such as programs that generate data, parameters that impact outputs, workflows…

As scientific research becomes more data intensive, there is an increasing need for scalable, reliable, and high performance storage systems. Such data repositories must provide both data archival services and rich metadata, and cleanly integrate with large scale computing resources. ROARS is a hybrid approach to distributed storage that provides…

This study examines why and how science and social science faculty at predominantly undergraduate colleges engage in undergraduate research (UR) while successfully attending to their scholarly and professional responsibilities. Given the increase in attention to UR as an innovative practice enhancing undergraduate education, most studies have…

Annotations play an increasingly crucial role in scientific exploration and discovery, as the amount of data and the level of collaboration among scientists increases. There are many systems today focusing on annotation management, querying, and propagation. Although all such systems are implemented to take user input (i.e., the annotations…

This dissertation presents three interrelated studies examining opportunities for student learning through contributory citizen science (CS), where students collect and contribute data to help generate new scientific knowledge. I draw on sociocultural perspectives of learning to analyze three cases where teachers integrated CS into school science,…

This dissertation presents a multidisciplinary means of determining the actual content (foodstuff, non-foodstuff, or lack of contents) of Classic Mayan (A.D. 250-900) vessels. Based on previous studies that have identified the residues of foodstuffs named in hieroglyphic texts (e.g. cacao), this study is designed to further investigate foodstuff…

In modern research activities, scientific data sharing is essential, especially in terms of data-intensive science and scholarly communication. Scientific communities are making ongoing endeavors to promote scientific data sharing. Currently, however, data sharing is not always well-deployed throughout diverse science and engineering disciplines.…

Research is an important aspect of academic institutions as it brings funding, reputation, and other benefits to the associated establishment. Research misconduct in the form of plagiarism, fabrication, and falsification can occur in association with research, along with subsequent penalties. The problem of the poorly established prevalence of the…

In this dissertation I examine Indigenous Knowledge Systems (IKS) and Western science, critically analyzing the underlying values of each, and exploring ways in which both systems can be utilized side by side. In general, Western science has arguably become the worldview utilized in dealing with the many complex multi-level issues of today.…

This dissertation looks at the effects of an educator-scientist partnership on the creation of an inquiry based science lesson for the middle school classroom. The lesson was initially created by a scientist following their science research, but changed as the scientist began working with teachers. The changes in the lesson show that scientists…

This dissertation introduces the construct of "worthwhileness" as an important aspect of students' "practical" epistemologies of science (Sandoval, 2005). Specifically, it examines how students conceptualize what makes a scientific research question worthwhile, through a close analysis of the criteria they use for…

Quantum mechanical (QM) and molecular docking methods are used to probe systems of biological and synthetic interest. Probing interactions of nucleobases within proteins, and properly modeling said interactions toward novel nucleobase development, is extremely difficult, and of great utility in RNA interference (RNAi) therapeutics. The issues in…

After decades of attempting to identify effective reading programs within the United States, in recent years, the emphasis on identifying these programs has made a dramatic shift. The continuous increase in federal involvement began the implementation of No Child Left Behind (NCLB). One of the primary goals for NCLB is to drastically improve…

Scientific discoveries take place within scientific communities that are established in legitimating organizations such as universities and research institutes. Often times, scientists undergo tensions and paradoxes as they evaluate the risks they are willing to accept in their work. The types of risk/benefit decisions scientists make to determine…
