Multi-User Virtual Environments for Learning: Experience and Technology Design
Full text linkMulti-User Virtual Environments are often used to support learning in formal and informal educational contexts. A technology-based educational experience consists of several elements: content, syllabus, roles, sequence of activities,
assignments, assessment procedures, etc. that must be aligned with the affordances of the technologies to be used. The design
process, therefore, has to follow a dual track: the design of the educational experience as a whole and the design of the MUVE.
Each design process has some degree of independence, while, at the same time, the two design processes are also deeply
intertwined. The paper proposes a novel approach to design (both for the educational experience and the MUVE): a “biological
lifecycle” design, where evolution (for survival and fitness) is crucial, while anticipating all the requirements (creating an engineering blueprint) is very challenging. This paper is based upon a number of large-scale case studies, involving nearly 9,000 high-school students from 18 countries in Europe, Israel, and the USA. Substantial educational benefits were achieved by these learning experiences, at the center of which were MUVEs. It can’t be claimed that MUVEs were the only factors for generating these benefits, but for sure they were exceptionally important components
Il software open-source nel sistema universitario italiano
No full textIl software open source ha sempre trovato una forte spinta propulsiva nell’ambiente accademico, che ha contribuito in maniera decisiva al suo sviluppo. Pur tenendo presente che prodotti open source sono ormai largamente diffusi nel mondo del software industriale, può essere interessante cercare di capire quanto nell’ambiente universitario è poi concretamente anche adottato per le infrastrutture e i servizi. Il censimento del software open source vuole proprio rispondere a questa domanda per offrire una base di partenza da utilizzare per monitorare in futuro l’evoluzione di queste tecnologie. La conoscenza della diffusione dei software open source all’interno del sistema universitario italiano può essere di interesse non solo per il sistema stesso, ma anche per la definizione di politiche strategiche per la pubblica amministrazione in senso più generale
Deploying Virtual Worlds for Education in Real Schools
No full textBetween 2002 and 2008, we have developed and deployed four educational programs based on Multi-Users Virtual Environments (MUVEs): more than 9,000 students from Europe, USA and Israel took part in MUVEs based experiences in the context of formal education, i.e. at school, as part of a curricular activity and not as a “recreational experimentation” of technology (Figure 1). The different programs had a similar pattern, with a technology and an architecture that evolved over the years
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
