High School Students’ Use of Digital General Resources During Lockdown
Full text linkThere is not a large body of literature about digital resources found and accessed autonomously by high school students while studying mathematics, whereas this topic has become more and more relevant in times of lockdown due to the pandemic. Italy has been one of the first countries facing lockdown for an extended time, making this country a paradigmatic example: in this paper we investigate what kind of digital resources are accessed by the Italians high school students who actually use them and why. According to our results, students’ aims and expectations vary according to the school grade, but are not as much devoted to procedural learning as previous literature has shown. Also, we observe that the type of searched media (text, video, image, etc.) is related to the mathematical contents and to students’ objective
A longitudinal analysis of the Italian national standardized mathematics test
No full textThis paper presents a longitudinal analysis of the outcomes of the Italian national standardized mathematics tests. By intertwining quantitative and qualitative methods, we selected and analysed a set of linked questions among the tests administered to the same cohort of students first in grade 6 and then in grade 8. In particular, we focus on poor knowledge students and we argue an example of the analysis of two linked questions about graphical representation of fractions. The comparison between the two questions allows us to interpret some difficulties of students and to expect possible future behaviours
L’auto-efficacia e le emozioni verso la matematica dei futuri insegnanti di scuola dell’infanzia e primaria.
Full text linkStudying of teachers’ self-efficacy and its sources is a relevant topic in the field of mathematics education. In this contribution we present a study about the relations between emotions towards mathematics and its teaching of pre-service teacher and their self-efficacy toward mathematics teaching. The paper describes an observational-correlational research on a sample of students enrolled in the “Scienze della Formazione Primaria” master degree. Results show the existence of a strong correlation between emotions towards mathematics and its teaching and the self-efficacy related to this subject. Hence, data are coherent with the idea of working on emotions of future teachers towards mathematics and its teaching to influence their self-efficacy. From collected data, we can also observe that emotions towards mathematics, both positive or negative ones, are correlated respectively to positive and negative emotions towards its teaching
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
