EPORTFOLIO IN PRIMARY SCHOOLS. USING MAHARA TO ENHANCE REFLECTIVE LEARNING AND MOTIVATION
Full text linkThis paper aims to highlight how the use of a specific ePortfolio tool, Mahara, within a primary school has led students to a different perception of the subjects and the content of the lessons studied. Writings produced by 18 students during the last year of primary school will be investigated in order to show how the use of ePortfolios could support reflection and construction of a personal learning path in 11 years old students. In addition, this research will highlights how the use of ePortfolios could produce an improvement of learning through the stimulation of students’ motivation. The analysis of the activities and comments shows how, starting from a partial reflective attitude, and from the perception of the single lesson as an isolated event, students learn to reflect on their learning pathways, generating views that try to grasp the meaning of the whole learning path and the relationship between their learning and the future development of their student career. Starting from a limited reflecting attitude through which students could only discuss their present time, the improvement of their reflective skills could support them to plan their future. Some features of the tool used, such as its friendly “look and feel” and its structure, similar to that of many social software, have acted as a powerful motivational factor in overcoming difficulties often associated with the use of ePortfolios
A literature review on Intelligent Tutoring Systems and on student profiling
No full textPersonalization represents a discussed topic among the scientific community that deals with Intelligent Tutoring Systems (ITS). To allow a meaningful personalization ITS requires good procedures to generate detailed user profiles. User profiles are built referring to different models that focus on various characteristics of the students, related to various aspects that are considered crucial during the learning process. The aim of this paper is to outline a detailed overview on the main progresses made in the field of user modeling and user profiling
Mahara in secondary school. The introduction of an ePortfolio to foster oral skills and socialization.
No full textThe present paper intends to present a project carried out in a secondary school during the current school year, where the adoption of an open source ePortfolio system, Mahara, was proposed. The research aim was to promote the use of the tool for the three-year of duration of the course. At the end of the first year of testing, we plan to document the influence that this tool has had in the life of the class with respect to three main dimensions: (a) the attitude that students had towards the disciplines, (b) the way students change their study methods within the portfolio, (c) the relationships and the climate inside the classroom
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
