The role of a journal on teaching mathematics and sciences issued at the beginning of the 20th century in professionalizing Italian primary school teachers
No full textThis chapter examines the first non-ephemeral journal on teaching mathematics and sciences in primary school, which appeared at the beginning of the twentieth century in Italy. The project of publishing such a kind of journal is set in the context of the initiatives launched in the new Italian nation for creating a course of studies specifically addressed at educating primary school teachers. We outline the mission and vision of the journal by presenting the personality of the founder Alberto Conti (a leading character among the secondary school mathematics teachers of the period), and analyzing the content of the journal. The subjects treated were sciences and mathematics, but mathematics was the prevailing subject covered in the journal because its importance in primary education and the strong mathematical background of Conti. Most contributors, including the editors, were mathematics teachers in Italian schools for prospective primary teachers (Scuole Normali); their contributions reflect firsthand experience in this context. To involve the readers the journal published questions addressed to primary school teachers and to students of Scuole Normali. It is remarkable that female students were very active in answering the questions
Visualisation, imagery, and the development of geometrical reasoning
No full textThis report focuses on some aspects of the nature and role of visualisation and imagery in the teaching and learning of mathematics, particularly as a component in the development of geometrical reasoning. Issues briefly addressed include the relationship between imagery and perception, imagery and memory, the nature of dynamic images, and the interaction between imagery and concept development. The report concludes with a series of questions that may provide a suitable programme for research and lays the foundation for further work of the BSRLM geometry working group
The mathematical journals for teachers and the shaping of teachers’ professional identity in post-unity Italy
No full textThe importance of the mathematical journals for teachers published in Italy in the second half of nineteenth century is multifaceted. Beyond their obvious role of spreading the mathematical culture, they created a net of contacts that fostered shaping the identity of Italian mathematics teachers and provided the terrain for initiatives such as the creation of the Italian association of mathematics teachers Mathesis. The aim of the present contribution is to outline the personalities of the founders to single out elements that contributed to shaping mathematics teachers’ professional identity in the newborn nation

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
