Students' evaluation of online course materials in Fixed Prosthodontics: a case study

EUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 2 2001
Elizabeth S. Pilcher
Purpose: The purpose of this study was to assess a new online course format for dental students. Preclinical Fixed Prosthodontics I is a didactic and laboratory course given in the first year of the dental school curriculum. In the spring semester of 1999, the didactic portion of the course was offered in a web-based format as a supplement to the traditional lecture format. Methods: The study population was 53 first year dental students at one school. The study design was a one group post test without a control group. The online questionnaire consisted of multiple choice questions, Leikert scale questions and open-ended questions. Data were collected using Filemaker Pro and analyzed using EpiInfo. Results: Student response rate was 96% (52/53). All of the students responded that they felt comfortable with their computer skills in utilizing this course format. Most (96%) responded that the online materials were either very helpful or helpful to them. About half, (54%) recommended that the online format be continued as a supplement to traditional lectures, while 28% recommended replacing traditional lectures with the new format in order to provide more laboratory time in the course. The syllabus, lecture materials, bulletin board and handouts were found to be the most helpful online features. The least helpful features were the listserve, decision tree, and e-mail options. Most frequently mentioned strengths of the online material were listed as 1) the ability to view material at their own pace and at a time convenient to them, 2) quality photographs in lecture materials and 3) online quizzes. Weaknesses of the course were ranked by students as 1) problems with access to the materials and the intranet system, 2) taking quizzes online and 3) difficulty in printing the web-based lecture materials. Conclusions: The delivery of web-based material as a course supplement in Fixed Prosthodontics I was determined to be an overall success. Fine tuning of problems with access to the materials took place throughout the course. The student feedback will help direct future development of web-based course materials in the dental school curriculum. [source]


A Structural Solution to Communication Dilemmas in a Virtual Community

JOURNAL OF COMMUNICATION, Issue 3 2007
Dongyoung Sohn
In a many-to-many communication setting like a virtual community, individuals may be strongly tempted to free-ride on others' contributions, which would eventually lead to the collapse of the community. To find a structural solution to the "communication dilemma," this study compared the performances of 2 communication structures,one based on the interpersonal networks (network-generalized exchange: NEX; e.g., blogs) and the other based on a public electronic bulletin board (group-generalized exchange: GEX). In a 2 × 2 × 2 longitudinal between-subject experiment, it was found that changing GEX to NEX could increase the contributions made by individuals. Furthermore, NEX was found to be an effective structure for N-person communication particularly when a large number of individuals were involved. The findings imply that an individual's cooperative motivation is a function of the incentive structure of a particular form of information exchange, which means that altering the exchange form may be a possible solution to the communication dilemmas in virtual communities. Résumé Une solution structurelle aux dilemmes de communication dans une communauté virtuelle Dans un contexte de communication multivoque comme celui d'une communauté virtuelle, les individus peuvent être fortement tentés de profiter des contributions des autres tout en s,abstenant eux-mêmes de contribuer, ce qui en définitive mènerait à l'effondrement de la communauté. Afin de trouver une solution structurelle au « dilemme de communication », cette étude a comparé le rendement de deux structures de communication : l,une fondée sur les réseaux interpersonnels (NEX)(p. ex. les blogues) et l'autre s,appuyant sur un babillard électronique public (GEX). Dans le cadre d'une expérience longitudinale inter-sujets de 2 x 2 x 2, il est apparu que de changer GEX pour NEX pourrait augmenter le nombre de contributions faites par des individus. De plus, il fut observé que NEXétait une structure efficace pour la communication N personnes, particulièrement lorsqu,un grand nombre d'individus étaient impliqués. Les conclusions laissent entendre que la motivation incitant à coopérer d,un individu est fonction de la structure incitative d'une forme particulière d'échange d,information, ce qui signifie que de modifier la forme de l'échange peut être une solution possible aux dilemmes de communication dans les communautés virtuelles. Abstract Ein struktureller Lösungsansatz bei Kommunikationsdilemmata in virtuellen Gemeinschaften In einer Vielpersonen-Kommunikationsumgebung, wie z.B. virtuellen Gemeinschaften, können Personen leicht in Versuchung geraten, ohne eigene Anstrengung von anderen Teilnehmern zu profitieren, was letztendlich zum Zusammenbruch der Gemeinschaft führen kann. Um eine strukturelle Lösung zu diesem "Kommunikationsdilemma" zu finden, wurden in dieser Studie zwei Kommunikationsstrukturen hinsichtlich ihrer Leistung verglichen: eine Struktur basierend auf interpersonalen Netzwerken (NEX) (z.B. Blogs) und die andere basierend auf einem öffentlich zugänglichen elektronischen Forums (GEX). In einem Längsschnittexperiment (2x2, between-subject-design) konnte gezeigt werden, dass ein Wechsel von GEX zu NEX mit einem Zuwachs der Individualbeiträge einherging. Darüber hinaus zeigte sich NEX als effektive Struktur für N-Personen- Kommunikation, besonders dann, wenn eine größere Anzahl an Individuen beteiligt ist. Die Ergebnisse deuten darauf hin, dass die Motivation einer Person zur Kooperation die Funktion der Anreizstruktur einer bestimmten Form des Informationsaustauschs ist. Dies bedeutet, dass eine Veränderung der Austauschsform eine mögliche Lösung für Kommunikationsdilemmata in virtuellen Gemeinschaften sein kann. Resumen Una Solución Estructural a los Dilemas de Comunicación en una Comunidad Virtual En escenarios de comunicación de muchos contra muchos como lo es en una comunidad virtual, los individuos pueden estar tentados fuertemente de aprovechar las contribuciones de los otros, lo cual puede eventualmente llevar al colapso de la comunidad. Para encontrar una solución a este "dilema de comunicación," este estudio comparó el rendimiento de 2 estructuras de comunicación , una basada en una red interpersonal (NEX)(a saber, blogs) y la otra basada en un tablón público de anuncios (GEX). En un experimento longitudinal entre sujetos 2 x 2 x 2, se encontró que cambiando GEX por NEX puede incrementar las contribuciones hechas por los individuos. Más aún, se encontró que NEX era una estructura más efectiva para la comunicación de N-persona particularmente cuando un número grande de individuos estuvieron involucrados. Los resultados significan que la motivación de cooperación de un individuo está en función de la estructura de incentivo de esa forma particular de intercambio de información, lo que significa que alterando la forma de intercambio puede ser una solución posible al dilema de comunicación de las comunidades virtuales.

Enriching spaces in practice-based education to support collaboration while mobile: the case of teacher education

JOURNAL OF COMPUTER ASSISTED LEARNING, Issue 4 2007
E.M. Morken
Abstract Practice-based education is gaining a growing popularity in fields as diverse as, for example, software engineering, pedagogy and medical studies. In practice-based education learning takes place across different learning arenas and requires cooperation among all the actors involved in the learning process. However, mobility of students across these arenas impact deeply on cooperation patterns, and therefore on the learning process. In this paper we investigate the usage of shared display systems to promote cooperation among students in practice-based education. Our focus is on teacher education and the paper is based on our experiences with the teacher education programme at our university. Based on our observations of students out in practice, we discuss the importance of common spaces and the role of bulletin boards of different types. We then define high-level requirements for a shared display system to support practice-based education and we illustrate the main concepts with a demonstrator. Strengths and weaknesses of our approach are pointed out through an evaluation of the demonstrator. [source]

Brand community: Drivers and outcomes,

PSYCHOLOGY & MARKETING, Issue 4 2010
Nicola Stokburger-Sauer
Groups of users and admirers of a brand who engage jointly in group actions to accomplish collective goals and/or to express mutual sentiments and commitments are known as brand communities. Lately, brand communities have been a heavily researched topic in marketing science. While the positive consequences of brand communities are well documented in the literature, little is known about how brand communities can be facilitated and how consumer,brand relationships can be fostered. This research empirically assesses the relevance of offline (i.e., events) and online marketing management tools (i.e., Web sites with online bulletin boards and online expert chats) to strengthen brand communities by facilitating shared customer experiences and multi-way interactions. Additionally, the importance of consumer,brand identification as a consequence of such relationship-building activities is investigated, and the outcomes of a consumer's identification with a brand are analyzed. Important management implications can be derived. © 2010 Wiley Periodicals, Inc. [source]
