Scientific data visualizations are the products, and increasingly a core practice, of modern computational science across all domains. With recent science education standards emphasizing student engagement in practices, these scientific visualizations will only increase in their availability and use for K-12 science instruction. But teacher…

Organizations face many cybersecurity threats. Among those threats, social engineering attacks such as phishing stand out as a constant and costly struggle. The primary tools for combating social engineering are information security policy (ISP) and security awareness training (SAT), which seek to inform users of the threat of social engineering,…

As next-generation space exploration missions require increased autonomy from astronaut crews, real-time diagnostics of astronaut health and performance are essential for mission operations, especially for determining Extravehicular Activity (EVA) readiness. Exposure to microgravity leads to changes in astronaut physiology such as loss of bone…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…

In this study, I conduct a quantitative analysis to assess the attitudes of Black male high school sophomores towards STEM content through a unique informal STEM learning program called ESTEAM offered by the non-profit organization Class Matters Inc. The students participated in a pre- and post-survey based on Mark Mahoney's Attitudes towards STEM…

The use of technologies in and outside classrooms has attracted young adolescents who must be prepared to embrace the opportunities and face new challenges in the 21st century. Educational systems across the US continue to gravitate toward new technologies such as digital cameras, interactive-boards, and software that have been shown to enhance…

This dissertation evaluates Instructor's practical knowledge in effectively delivering instruction in Federally Funded Research and Development Centers (FFRDC). Through semi-structured interviews, observation, and document analysis this investigation explored the skill sets of seven space technical instructors conducting highly technical…

With the continual growth and demand of online courses, higher education institutions are attempting to meet the needs of today's learners by modifying and developing new student centered services and programs. As a result, faculty members are being forced into teaching online, including Earth and Space science faculty. Online Earth and Space…

This study explores the experiences of 4th grade students in an inquiry-based space science classroom. At the heart of the study lies the essential question: What is the lived experience of children engaged in the process of space science inquiry? Through the methodology of phenomenological inquiry, the author investigates the essence of the lived…

The current Situational Space Awareness (SSA) is faced with a huge task of tracking the increasing number of space objects. The tracking of space objects requires frequent and accurate monitoring for orbit maintenance and collision avoidance using methods for statistical orbit determination. Statistical orbit determination enables us to obtain…

A 30-year contribution of the Space Shuttle Program is the evolution of NASA's social actions through organizational learning. This study investigated how NASA learned over time following two catastrophic accidents. Schwandt's (1997) organizational Learning System Model (OLSM) characterized the learning in this High Reliability…

A modern space mission is assembled from multiple phases or events such as impulsive maneuvers, coast arcs, thrust arcs and planetary flybys. Traditionally, a mission planner would resort to intuition and experience to develop a sequence of events for the multiphase mission and to find the space trajectory that minimizes propellant use by solving…

The purpose of this study was to examine the role of an online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of…

The purpose of this study was to investigate whether or not there have been successful applications of lean manufacturing principles in highly variable defense IT environments. Specifically, the study assessed if implementation of the lean philosophies by a defense organization yielded repeatable, predictable results in software release schedules…
