COLLABORATIVE CONSTRUCTION OF SCRATCH PROJECTS WITH 9-11 YEAR OLD STUDENTS DURING COVID-19 LOCKDOWN
No full textWhen the COVID-19 pandemic caused all Italian schools to close in March 2020, four classes of an
Italian primary schools were busy creating Scratch projects aiming at a final event at the end of the
school year. As all teaching activities moved online, teaching time was reduced in order to maintain
students’ daily computer hours to an acceptable level. In this context, the students were offered the
opportunity to continue their project on a voluntary basis, giving them the possibility to regularly meet
their peers and work collaboratively. Activities were reorganized to adapt them to the online environment,
weekly meetings were devoted to the discussion of the ongoing activities and problem resolution, while
programming was autonomously managed by the students. 81% of the students decided to actively
participate, and they all had a complete project to present at the final event. The paper presents the
organization of the online activities and some observations along with a short discussion on pros and
cons of the online programming activities
Il punto di vista delle insegnanti. Report sull'analisi della realizzazione del progetto “Coding e robotica”
No full textQuando si parla di coding e robotica educativa, argomenti da alcuni anni di estrema attualità nel campo dell’educazione, è impossibile prescindere da due aspetti tra loro complementari: la tecnologia, che comprende le competenze algoritmiche, di programmazione nonché la scelta ponderata degli strumenti; e l’inserimento di tali attività nel curricolo e in contesti interdisciplinari per integrare la complessità dei saperi con metodologie proprie della didattica laboratoriale. Il volume descrive l’impianto di ricerca, la cornice metodologica e le considerazioni tecniche del progetto PON “Coding e Robotica” sviluppato dagli autori e sperimentato nella scuola dell’infanzia e del primo ciclo nell’anno scolastico 2019-20. L’analisi delle esperienze dei docenti coinvolti non presenta solo i risultati del progetto, ma fornisce agli insegnanti interessati anche delle linee guida per inserire il coding e la robotica educativa nel loro lavoro in class
Online Scratch Programming With Compulsory School Children During COVID-19 Lockdown: An Italian Case Study
No full textIn Spring 2020, the COVID-19 health emergency caused all Italian schools to close from March to the end of the school year. An intervention was organized with the aim of offering primary and lower secondary teachers the possibility to organize remote coding activities with their students. Nine workshops were held to introduce teachers to the Scratch online programming environment, and then a coding day was organized involving students from the last year of primary and lower secondary schools. The chosen activities proved to be motivating to the students, favoring social interactions and participation, and increasing their interest in coding. Teachers were positively impressed by the ease with which their students managed programming in Scratch, but some of them felt that they did not master programming well enough to autonomously support class activities. A longer teacher training period is needed
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
