Many university administrators are unaware of the increasing use of computer technologies for educating employees. This study explored higher education administrators' perceptions of computer technology for university administrator learning. A treatment group of UC Berkeley administrative employees was assigned to use an online simulation; a…

This dissertation explores the use of geometric and graphical models for a variety of information search and filtering applications. These models serve to provide an intuitive understanding of the problem domains and as well as computational efficiencies to our solution approaches. We begin by considering a search and rescue scenario where both…

Competency standards require baccalaureate nursing graduates to demonstrate knowledge, understanding, and the ability to solve complex problems. In an effort to achieve these program outcomes, educators seek empirical evidence related to the learning process and the effect of innovative teaching strategies, such as simulation, on the learner.…

Through an examination of the underserved urban population, this paper takes a look at how the use of games and simulations may provide a means of closing a gap in education which has lingered for several decades. Discussion on how this engagement might look as both a class learning algebra through game programming and gameplay is reviewed. As…

To develop sustainable solutions to remediate the complex ecological problems of earth's soil, water, and air degradation requires the talents and skills of knowledgeable, motivated people (UNESCO, 1977; UNESCO, 2010). Researchers historically emphasized that time spent in outdoor, nature activities (Wells & Lekies, 2006), particularly with an…

This study explored the development of student's conceptual understandings of limit and derivative when utilizing specifically designed computational tools. Fourteen students from a secondary Advanced Placement Calculus AB course learned and explored the limit and derivative concepts from differential calculus using visualization tools in the…

This dissertation introduces a new multimedia security system for the performance of object recognition and multimedia encryption in security and medical applications. The system embeds an enhancement and multimedia encryption process into the traditional recognition system in order to improve the efficiency and accuracy of object detection and…

Despite the speed at which Second Life has been adopted by universities and schools to teach courses, little educational research and theory addresses this multiplayer online "world." This case study explored undergraduate university instructors' teaching methods and tools within a virtual environment. It also considered whether instructors are…

For the first time in the history of collective action, the offline world has experienced a virtually organized and enacted union strike. While this was the first publicly noticed political action in a virtual world, others have been going on for several years now. As virtual worlds continue to grow in popularity, this type of protest of action…

Scope and method of study. The purpose of this study was for the researcher to obtain a better understanding of the online learning environment, to explore the various ways online class instructors have incorporated digital communication applications to try and provide learner-centered online learning environments, and to examine students'…

Backpackers are pioneers of mobility, who provide a unique domain for critical tourism research. The lineage of backpacker ideals, including pursuit of authentic experiences, independence, escape and social interaction, can be traced back to the "tramps" of the 1880s and the "drifters" of the 1970s. The recent emergence of the…

In recent years, technological advances such as computers have been employed in teaching gross anatomy at all levels of education, even in professional schools such as medical and veterinary medical colleges. Benefits of computer based instructional tools for gross anatomy include the convenience of not having to physically view or dissect a…

The purpose of this study was to determine the effects of interactive multimedia simulations and virtual dissection software on depth of learning among students participating in biology and chemistry laboratory courses. By understanding more about how simulation and virtual dissection software changes depth of learning, educators will have the…

This study examines perceptions of human "trustworthiness" as a key component in countering insider threats. The term "insider threat" refers to situations where a critical member of an organization behaves against the interests of the organization, in an illegal and/or unethical manner. Identifying and detecting how an individual's behavior…

This quantitative survey study examines the willingness of online students to adopt an immersive virtual environment as a classroom tool and compares this with their feelings about more traditional learning modes including our ANGEL learning management system and the Elluminate live Web conferencing tool. I surveyed 1,108 graduate students in…
