CHILDREN CONSTRUCT COHERENT ARGUMENTATION AND FORMAL THINKING ON ENERGY IN A CONCEPTUAL LAB OF OPERATIVE EXPLORATION (CLOE)
No full textCONCEPTUAL LABORATORIES OF OPERATIVE EXPLORATION (CLOE) TO BUILD FORMAL THINKING IN BASIC SCHOOL: THE CASE OF SOUND
No full textThe design of innovative didactic sequence on a specific topic requires, in the Model of Educational Reconstruction perspective, besides the conceptual contents reconstruction, knowledge of students' conceptions about the topic focused. Conceptual Laboratories of Operative Exploration (CLOE) were designed with the goal of gaining direct knowledge on how students, particularly younger children (kinder-garden, primary, middle school), approach to specific topics and to the operative proposals, through which the innovative educational proposals are developed. CLOE lab involves pupils to discuss everyday life scenarios, recover their everyday and sensorial knowledge, explore experimental situations by means of Inquiry-Based Learning strategies. The informal learning environment of a CLOE session is an ideal format also for research focused on students’ ideas and reasoning patterns, how they build formal thinking, develop interpretative representations, construct models on phenomena, reinterpret everyday knowledge. The research design characteristics of the CLOE labs are presented, exemplifying it, in the case of sound in primar
Toward Semantic Digital Libraries: Exploiting Web2.0 and Semantic Services in Cultural Heritage
No full textDeveloping and maintaining a digital library requires substantial investments that are not simply a matter of technological
decisions, but include also organizational issues (user roles, workflows, types of contents, etc.). These issues are often
handled by approaches based on a physical perspective that treats the stored information either in terms of data formats or
physical space needed to archive them. All these perspectives completely ignore the semantic aspects of the digital contents.
In this paper, we address such a semantic perspective. More specifically, we propose a service-oriented architecture that
explicitly includes a semantic layer which provides primitive services to the applications built on top of the digital library. As
part of this layer, a specific component is described: the PIRATES framework. This module assists end users to complete
several tasks concerning the retrieval of the most relevant content with respect to a description of their information needs (a
search query, a user profile, etc.). Techniques of user modeling, adaptive personalization, and knowledge representation are
exploited to build the PIRATES services in order to fill the gap existing between traditional and semantic digital libraries
Dall’esperimento al modello con la LIM nella scuola di base: il caso dell’ottica
No full textLa LIM permette di costruire personali rappresentazioni a partire da foto, disegni, schemi. Offre quindi l’opportunità di utilizzarla nella didattica scientifica per costruire un ponte tra l’esplorazione sperimentale dei fenomeni e la costruzione di modelli via via più formalizzati. L’ottica è un contesto che si presta particolarmente per sviluppare proposte didattiche che aiutano gli studenti anche della scuola di base a costruire rappresentazioni dei fenomeni fisici, favorendo lo sviluppo del pensiero formale. Alcune proposte sperimentate con un gruppo di 90 studenti di scienze della formazione primaria esemplificano alcune tra le principali potenzialità della LIM in questa prospettiva

Open Data Workshop
No full textPresented by: Rubab Shahzad (Data Visualization Librarian), Ryan Hendrick (Data Management Librarian), Morgan Rowe-Morris (Multidisciplinary Librarian), and Abhijit Challapalli (Libraries GRA)
This workshop will introduce what open data is, why is it important, and where it can be reliably found. We will go over open data policies, open data management plans, and different types of open datasets. This workshop will include a discussion of the ethics of using Artificial Intelligence (AI) for Open Science research with case studies/examples
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
