Game-Based Learning in Virtual Worlds: A Multiuser Online Game for Medical Undergraduate Radiology Education within Second Life

Game-based learning can have a positive impact on medical education, and virtual worlds have great potential for supporting immersive online games. It is necessary to reinforce current medical students' knowledge about radiological anatomy and radiological signs. To meet this need, the objectives of this study were: to design a competition-based game in the virtual world, Second Life and to analyze the students' perceptions of Second Life and the game, as well as to analyze the medium-term retention of knowledge and the potential impact on the final grades. Ninety out of 197 (45.6%) third-year medical students voluntarily participated in an online game based on self-guided presentations and multiple-choice tests over six 6-day stages. Participants and non-participants were invited to perform an evaluation questionnaire about the experience and a post-exposure knowledge test. Participants rated the experience with mean scores equal to or higher than 8.1 on a 10-point scale, highlighting the professor (9.5 ± 1.1; mean ± SD) and the virtual environment (8.9 ± 1.1). Participants had better results in the post-exposure test than non-participants (59.0 ± 13.5 versus 45.3 ± 11.5; P < 0.001) and a lower percentage of answers left blank (6.7 ± 8.4 versus 13.1 ± 12.9; P = 0.014). Competitive game-based learning within Second Life is an effective and well-accepted means of teaching core radiological anatomy and radiological signs content to medical students. The higher medium-term outcomes obtained by participants may indicate effective learning with the game. Additionally, valuable positive perceptions about the game, the educational contents, and the potential benefit for their education were discovered among non-participants.     

A systematic approach to analysing sports performance

A systematic approach to the analysis of sporting events is discussed. The basic tenet is that objective quantification of critical events is required for a complete analysis. This approach encompasses diverse areas of methodology and research, such as quantification, biomechanics and physiology. The theoretical underpinnings are behavioural, in so far as athletes produce observable behaviour that can be quantified and ultimately changed. Several areas of analysis are linked together in a general framework and each one of these areas is dealt with in detail.     

E-Readers: New Opportunities for Hospital Patients and Staff

E-readers provide an opportunity for hospital librarians to reach out to staff and patients with new approaches to library lending. Librarians in four Veterans Health Administration medical centers are using e-readers to enlarge their scope of service in unique ways. The libraries of VA hospitals in Minneapolis, Des Moines, Tampa, and Philadelphia have developed several ways to reach out to new library users.     

Editorial

The present qualitative research study addressed the overall research question of college students’ pretention dynamics in the context of a university setting. Thirty‐five Mac users were interviewed on a university campus that exclusively supports PC machines. Mac users shared four self‐admitted pretensions related to using Macintosh computers. First, participants asserted that Apple brand computers set social trends and that owning a Mac was perceived to make one to stand out positively. Second, Mac users shared their personal views that Macs are superior in technology and that PC technology is simply attempting to mimic Apple’s strides forward. Third, Mac users described various perceived social stigmas associated with owning Macs, such as the “artsy” label, the “cool” factor, and common socio‐economic assumptions associated with Mac ownership. The fourth dynamic of participants’ self‐admitted pretensions concerned their tendency to vocalize personal opinions of Mac’s superiority, with the aim of “converting” PC users.

Voreinstellungen von Mac Usern an einem überwiegend PC‐nutzenden Universitätscampus

Die vorliegende Qualitätforschungsstudie sprach die Bewahrungsdynamik der Collegestudenten im Kontext einer Universitätseinrichtenung an. Fünfunddreißig Mac Benutzer wurden auf einem Universitätscampus interviewt, der ausschließlich PC‐Maschinen unterstützt. Mac Benutzer bearbeiteten vier selbstdefinierte Ansprüche, die sich aus der Nutzung von Macintoshmaschinen ihrer Meinung nach ergaben. Erstens: Apple‐Computer erzeugen soziale Trends und der Besitz eines Mac‐Computers wurde für den Besitzer positiv bewertet. Zweitens: Mac‐Computer gelten als überlegene Technologie. PC‐Technologie versucht einfach, die Apple‐Technologie nachzuahmen. Drittens: Mit dem Besitz eines Mac werden auch soziale Wertungen verbunden, wie “artsy” Einstellungen oder der “cool”‐Faktor. Viertens: Es gibt eine Neigung, persönliche Meinungen der Mac‐Überlegenheit zur Beeinflussung von PC‐Benutzern zu verbalisieren.

Les prétentions avouées des utilisateurs de Mac sur un campus universitaire à dominante PC

La présente étude de recherche qualitative a porté sur les manifestations de prétention des étudiants dans un contexte universitaire. On a interviewé trente cinq utilisateurs de Mac sur un campus universitaire qui recommande l’usage exclusif des ordinateurs PC. Les utilisateurs de Mac ont reconnu qu’ils partageaient quatre préjugés par rapport à l’utilisation des ordinateurs Mac. Tout d’abord les ordinateurs de marque Apple vous marquent comme étant à la page sont perçus comme donnant une image positive de vous. Ensuite les Macs possèdent une technologie supérieure alors que la technologie PC semble n’être qu’une simple tentative pour imiter les avancées de Mac. Il y a ensuite des points négatifs que l’on associe à la possession des Macs comme le côté «bohême» et le facteur «sympa». Le quatrième point, c’est la tendence à crier haut et fort ce qu’on pense de la supériorité de Mac dans le but de «convertir» les utilisateurs de PC.

Las pretensiones reconocidas de los usuarios de Mac en un campus universitario donde prevalecen los PC

La presente investigación cualitativa trata de la dinámica presuntuosa de los estudiantes en el marco de un contexto universitario. Treinta y cinco usuarios de Mac han sido encuestados en un campus universitario que preconiza el uso exclusivo de los PC. Los usuarios de Mac segun sus propios testimonios compartían cuatro pretensiones en relación con el uso de los ordenadores Macintosh. En primer lugar los ordenadores de la marca Apple establecen modas sociales y la posesión de un Mac da la impresión de que Vd ofrece una imagen positiva. En segundo lugar, la tecnología de Mac es superior mientras la tecnología de los PC no es más que un intento para remedar los avances de Mac. En tercer lugar hay ciertos estigmas sociales acerca de la posesión de Macs, entre otros la etiqueta «bohemio» y el factor «majo». En cuarto lugar se nota la tendecia a expresar sus opiniones sobre la superioridad de Mac con el fin de «convertir» a los usuarios de PC.

A Discourse Analysis of Online Dialogs in Social Work Diversity Courses

Abstract

Online discussions can extend learning experiences beyond the time and space of the classroom, allowing students more time to process information, and an additional mode of expression for those who are less active in open classroom discussions. They may be especially appropriate for teaching sensitive or controversial subject matter such as oppression and diversity, which is required by the Council on Social Work Education. This study investigated topical themes, depth, and tone of online dialogs in social work diversity courses at two universities in the mid-Atlantic area. Discourse analysis-a type of content analysis-is employed to gain a deeper understanding of the learning experience, and to compare the impact of anonymous and identified participation in the dialogs.     

The Transition from Traditional Teaching to Web-Assisted Technology

Abstract

This research note presents a conceptual model for understanding how students embrace technology, briefly presents results of a pilot study supporting this conceptualization, and makes suggestions for web-assisted teaching and research. The conceptual framework helps the reader understand how instructors' “Marketing strategies” may need to change over the course of the semester to generate maximum acceptance of, and satisfaction with, high-tech classrooms. The conceptual framework is illustrated with data collected during a pilot study involving two web-assisted graduate foundation research courses at the Kent School of Social Work, University of Louisville. Students enrolled for two web-assisted research courses without knowing that web-assisted technology would be used in the course. The students' attitudes towards computers, their ability to access computers, as well as their skill levels in using computers were assessed. Suggestions and challenges for web-assisted teaching and research are provided based on the conceptual framework and results from the pilot study.     

HIGH TECHNOLOGY,EMPLOYMENT AND THE CHALLENGES TO EDUCATION

The contribution of employment in high technology industry to future employment growth in the US economy is estimated to be small. Much high technology employment is not professional work at all, but routine labour, and much of that performed by minority groups with few career opportunities. Most new jobs will occur in occupations requiring no more than secondary education. High technology may generate employment in other areas, but often low grade work performed in the “homework economy”. Appropriate education for employment in high technology industry and in computer-related fields is not necessarily specialised and technical; high-quality general education is probably more important. Instrumental education, ignorant of the demands of high technology, and of the demands a modern economy makes upon high technology, is likely to be counter-productive. Commercial and technical success requires a combination of cultural learning and technical skill.
