Maria Montessori e il suo metodo
No full textQuesta nota è un'introduzione all'opera di Maria Montessori. In essa sono descritti l'origine e i principi fondamentali della pedagogia scientifica montessoriana. Inoltre, sono analizzati gli elementi che caratterizzano il metodo, in particolare, il materiale educativo. Il lavoro ha lo scopo di consentire una rivisitazione di una proposta educativa che continua ad offrire impostanti spunti di riflessione su temi attuali, anche nell'ambito della costruzione della "mente matematica"
Centralità dei nodi concettuali in un modello didattico per affrontare le difficoltà in Matematica: pensiero geometrico.
No full textLa comunicazione riporta alcuni risultati ottenuti da attività sperimentali svolte per oltre un decennio e finalizzate al superamento delle difficoltà in matematica.
In tale contesto, è stato possibile rilevare che le cause delle difficoltà correlate alla didattica disciplinare sono da ricondursi alla inadeguatezza dei processi di costruzione dei nodi concettuali della disciplina. Le sperimentazioni condotte hanno consentito, inoltre, di confermare l'ipotesi. formulata a priori, circa la descrizione dell 'insieme dei nodi concettuali sui quali sono strutturati il pensiero
aritmetico-algebrico e quello geometrico, a livello scolastico. Qui viene proposta una riflessione sui nodi concettuali individuati, correlati al settore geometrico

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
El artivismo como mecanismo restaurador de memoria en las intervenciones urbanas de Resquicio Colectivo (Rosario-Argentina)
Full text linkLas búsquedas de Resquicio pueden enmarcarse dentro de las intervenciones urbanas, el arte en espacios no convencionales, el site specific, los flash mobs y demás variantes de eventos expresivos con los cuerpos como protagonistas. Pero esta 'definición' de los hechos que los convocan es sólo el gérmen de lo que postulan, dado que sus integrantes se definen como artivistas, separándose de asociaciones directas con las formas o localizaciones de sus acciones. Eligen la performance como modo y búsqueda de un cuerpo atento: antes, durante y posterior a lo que acontece. Por tanto, utilizan al arte como plataforma de denuncia, de reflexión y de inspiración, considerando que éste debe ponerse al servicio de todxs, fusionándose con lo cotidiano, porque lxs cuerpxs que atraviesan sus intervenciones son todxs: cuerpxs violentadxs, sin génerx o poligénerxs, los siempre sexuales/dxs (por acción u omisión), los siempre políticxs, los disidentes, los omitidxs, los cuerpxs desaparecidxs... Cuerpo de Memoria y Corpus Rotundum fueron algunas de las intervenciones sobre La Memoria colectiva/social, pero las demás performances, construyen una/otra Memoria asociada a la irrupción de lo crudo y real, por sobre el relato vívido/carnal (asumido absoluto) gestando una ruptura del Momentum (desambiguación) constituyendo huella.Fil: Ambrosini, Norma.

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
