HOW TO IMPROVE VISUAL-SPATIAL SKILLS THROUGH A DIGITAL ENHANCEMENT PROGRAM-Proceedings
No full textStarting from kindergarten, the child is called to experience a variety of elements drawn from his learning environment, so as to facilitate his transition to primary school (MIUR, 1991; MIUR, 2012; MIUR, 2018). The international literature (Kaldenberg et al., 2015; NAEYC 2009) argues that, at the base of literacy or mathematical skills, it is necessary to refine specific precursors for subsequent learning, such as visual and auditory discrimination, phonological awareness, manual eye coordination, visual-verbal association and phonological memory. In researching empirical evidence of the link between visual-spatial intelligence and the preschool period, a body of knowledge emerges regarding the criteria and the conditions for promoting cognitive enhancement paths through the use of interactive games. This paper aims to present the design approach of the VIEP-app software model (Calvani, Zanaboni, 2018), a user-friendly application for computers, tablets and smartphones, intended for preschool children to increase their visual-spatial skills to be used both in presence and at a distance. The authors intend to demonstrate how an ad hoc software application, if placed in systematically structured activities, offers to children the opportunity to understand spatial relationships, by refining their ability to discriminate shapes and colours, to manipulate objects or to identify positions in the space (Vegliante, Miranda, 2020). From a methodological point of view, this app is part of a wider program consisting of playful-interactive sessions of exercises differentiated by levels of difficulty. After an initial training phase, the teacher guides and supervises the child in interacting with digital devices through a touch screen by dragging, assembling, rotating or manipulating the figures and receiving vocal feedbacks able to maintain high motivation. The created software model allows interfacing with multiple communication channels simultaneously so as to enrich traditional learning experiences. In conclusions, there are some summary considerations on the possible progress of the research and with the aim of demonstrating in which situations and in what ways this kind of enhancement program can contribute to the elaboration of visual-spatial representations in preschool age
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
