    VCMS e ambienti di videocomunicazione: creare la videolezione e gestire la didattica sincrona

    No full text
    Il contributo analizza l'evoluzione dei sistemi CVMS e di videocomunicazione in ambito didattico. Nell’ultima decade, grazie alla diffusione della banda larga, l’uso del video nella formazione è notevolmente aumentato, inizialmente come contenuto da fruire in modo asincrono, più recentemente, occorsa la pandemia Covid-19, è stato diffuso soprattutto sotto forma di evento sincrono in sostituzione delle lezioni in presenza. Questa crescita significativa dell’uso del video ha promosso la diffusione dei cosiddetti vcms (video content management system), una sorta di estensione dei cms (content management system), le piattaforme dedicate alla gestione, archiviazione e allo streaming di video ottimizzati per la fruizione online

    DigComp as a Theoretical Framework for Media Education. Issues and Implications

    No full text
    This essay critically discusses the ways in which DigComp can be used as a theoretical framework to support media education programs in schools. Since 2006, digital competence has been one of the eight key competencies that were defined by the European Union for lifelong learning. As reported in the 2018 recommendations, these competencies are considered to be fundamental for each individual in a knowledge-based society. The spread of digital media in the recent years makes it seem like DigComp and media education can converge towards a singular aim of training responsible and aware citizens. However, an accurate analysis of the DigComp 2.1 framework indicates that the program does not allow the recognition of all the dimensions of media education (Kačinová, 2019; Swertz, 2019). DigComp focuses specifically on the acquiring of knowledge, recollection, comprehension, application, evaluation, and creation, without explaining the fundamental activities of critical analysis and reflection directly and extensively. The latter two dimensions form an integral part of the fundamental objectives of media education, which could enable students to make a truly conscious and responsible use of the new media. This discrepancy is probably due to the fact that, critical and reflective dimensions are included in three of the other seven key competencies (functional, alphabetical, citizenship, height, cultural, awareness, and expression) for European lifelong learning framework (2018), and require educational systems to propose the use of system-structured program-paths across several key competencies

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Get PDF
    We 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

    Formazione iniziale degli insegnanti tra identità professionale e motivazione: un’indagine pedagogica

    No full text
    Il contributo in parola presenta i risultati del questionario somministrato nella fase iniziale dei percorsi abilitanti, con l’obiettivo di delineare un quadro complessivo del gruppo di docenti e futuri docenti coinvolti. Lo strumento, concepito in chia ve qualitativa, ha permesso non solo di raccogliere dati anagrafici, motivazionali e professionali, ma anche di far emergere rappresentazioni, attese e bisogni formativi. Tale rilevazione si configura come momento fondativo del percorso, in quanto ha at tivato i partecipanti stimolandone riflessione e autorappresentazione, oltre a fornire elementi utili per orientare le attività didattiche. Nel complesso, il quadro restituito evidenzia un gruppo in formazione caratterizzato da motivazioni plurali, identità professionali in costruzione e una forte disponibilità al confronto, in linea con il ma cro-obiettivo del volume di documentare e valorizzare i processi di avvio e sviluppo dei percorsi abilitanti
