This dissertation proposes and tests a theory explaining how people make decisions to achieve a goal in a specific task environment. The theory is represented as a computational model and implemented as a computer program. The task studied was primary care physicians treating patients with type 2 diabetes. Some physicians succeed in achieving…

Air travel is expected to grow by a factor of 2 to 3 times by 2025 and people working in the aviation system, including airport personnel, pilots, and air traffic controllers, must be able to safely and efficiently operate in this arena ("NextGen"). In response to the personnel training and education requirements concomitant with "NextGen,"…

Tourism opportunities are being promoted heavily on the web, yet one of the largest and most lucrative markets, older adults are least likely to use the internet. In an effort to explore barriers to and potential acceptance of technology for tourism experiences, this study followed closely ten older adults through a learning process with…

We tested the hypothesis that training a parent in wheelchair-user and caregiver wheelchair skills would improve the child's wheelchair skills. We studied an 11-year-old girl with spina bifida and her mother. The mother received 4 training sessions averaging 42.5 minutes per session, over a period of 3 weeks. The total pre-training and, 4 weeks…

Objective: To develop an instrument to assess client-centered counseling behaviors (skills) of student-counselors in a standardized patient (SP) exercise. Methods: Descriptive study of the accuracy and utility of a newly developed counseling evaluation instrument. Study participants included 11 female student-counselors at a Midwestern…

This work presents the results of a study whose aim is to detect systematic errors about the concept of force among freshmen students. The researchers analysed the results of the Force Concept Inventory test, which was administered to two different groups of students. The results show that, although there were significant performance variations…

TRAKLA2 is a web-based learning environment for data structures and algorithms. The system delivers automatically assessed algorithm simulation exercises that are solved using a graphical user interface. In this work, we introduce a novel learning environment for spatial data algorithms, SDA-TRAKLA2, which has been implemented on top of the…

This study aimed to evaluate the integration of a simulation based learning activity on nursing students' clinical crisis management performance in a problem-based learning (PBL) curriculum. It was hypothesized that the clinical performance of first year nursing students who participated in a simulated learning activity during the PBL session…

In gifted education research, it is common for outcome variables to exhibit strong floor or ceiling effects due to insufficient range of measurement of many instruments when used with gifted populations. Common statistical methods (e.g., analysis of variance, linear regression) produce biased estimates when such effects are present. In practice,…

In this article, the author describes the Jazz Workshop, a unique blend of collaboration and constructivist learning using videoconferencing and Web 2.0 tools. Each summer it draws about 400 participants--mostly teachers, technology facilitators, teacher librarians, and videoconferencing coordinators--who convene in 20 locations across three…

This fall, the U.S. Supreme Court will hear arguments in a case that promises to affect the lives of many children. Up for debate is whether a law aimed at curbing children's access to violent video games violates their constitutional right to free speech. Signed 5 years ago by Governor Schwarzenegger, the California statute, which has yet to take…

This paper presents the results of a one-year experiment in incorporating active methodologies in a Queueing Systems course as part of the Telecommunication Engineering degree at the University of Zaragoza, Spain, during the period of adaptation to the European Higher Education Area. A problem-based learning methodology has been introduced, and…

Several lines of evidence demonstrate that the motor system is involved in motor simulation of actions, but some uncertainty exists about the consequences of lesions of descending motor pathways on mental imagery tasks. Moreover, recent findings suggest that the motor system could also have a role in recognition of body parts. To address these…

The objective of this research was to examine the effects of the instruction method "thinking actively in an academic context (TAAC)" on thinking skills, creativity, self-regulation and academic achievement. The design was pre-test-intervention-post-test with control group. The sample included 46 participants (aged 16 to 18 years), 24 experimental…

The virtual patient is a case-based computer program that combines textual information with multimedia elements such as audio, graphics, and animation. It is increasingly being utilized as a teaching modality by medical educators in various fields of instruction. The inherent complexity of older patients and the shortage of geriatrics educators…
