Analyser l’usage didactique d’un EIAH en mathématiques : une tâche nécessairement complexe
No full textIn this paper, we are interested in the analysis of the instructional use of mathematical ILE. First, we will describe the evolution of «problematics » in research studies dealing with this subject over the last ten years. After a period of studies mostly based on a postulate of learning improvement, some didactical phenomena were highlighted. This has led to the development of theoretical approaches which allow to take into acccount these phenomena. We will introduce the instrumental and ecological approaches with examples. Secondly, we will present a collaborative research that aims to underline processes for analysing studies concerning the integration of ILE into mathematics teaching. This study confirms the necessity of varying approaches in order to grasp the complexity of the instructional use of an ILE. We will briefly describe the methodology and the main results in relation to the phenomena previously mentioned.Dans cet article, nous nous intéressons à l’analyse de l’usage des EIAH dans l’enseignement des mathématiques. Dans une première partie, nous décrivons l’évolution des problématiques de travaux portant sur ce thème depuis une dizaine d’années. Après une phase de recherches basées, pour la plupart d’entre elles, sur un postulat d’amélioration de l’apprentissage, l’identification de certains phénomènes didactiques a conduit au développement de nouvelles approches théoriques permettant de prendre en compte ces phénomènes. A l’aide d’exemples, nous introduisons succinctement les approches instrumentale et écologique. La deuxième partie présente une recherche de plusieurs équipes visant à étudier les travaux existants pour dégager une démarche d’analyse de l’intégration des EIAH dans l’enseignement des mathématiques. Cette étude confirme la nécessité de diversifier les approches pour appréhender la complexité de l’usage didactique d’un EIAH. Nous décrivons brièvement la méthodologie et les résultats de cette recherche en relation avec les phénomènes décrits précédemment.Guin Dominique, Trouche Luc.

Evidencing Missing Resources of the Documentational Approach to Didactics. Toward Ten Programs of Research/Development for Enriching This Approach
Get PDFInternational audienceThis chapter proposes a view from inside the DAD, starting from determining some essential resources missing of DAD, to proposing 10 programs of research/development for developing it. It could be considered as a follow-up of Chapter 1, where Ghislaine Gueudet situates the current state of DAD in looking back to its origin: chapter 12 proposes a possible future of this approach in analyzing its current state. It determines the missing resources of DAD in questioning current and past PhD students who have anchored their research in DAD. What did/do they learn in using DAD as a main theoretical resource; to which extent did/do they estimate that they have enriched DAD by their own work? Which are, according to them, the still missing resources of DAD? Which of these resources should be developed by DAD from itself, and/or in co-working with other theoretical framework? From this inquiry, this chapter proposes ten perspectives of research, aiming to develop some theoretical blind points of DAD, or to develop some methodological tools, or to deepen the cultural/social aspects of DAD in questioning the naming systems used by teachers when interacting with resources. This chapter echoes actually different perspectives of research already present, as promising germs, in previous chapters of the book
Transitions towards digital resources: change, invariance and orchestration
Get PDFThis chapter reports on the work of Working Group 4 and focuses on the integration of digital resources into mathematics teaching and learning practices. There are five central sections, focusing on, namely instrumental genesis, instrumental orchestration, the documentational approach to didactics, digital resources and teacher education, and the design of learning environments with the use of digital resources. A range of constructs and theoretical approaches are covered in these five sections, and the opening section comments on construct validity and issues in “networking” theoretical frameworks. The chapter can be viewed as a literature review which surveys past and present (at the time of writing) scholarship with an eye to possible future research. The chapter is extensive in several dimensions: a large range of digital resources and applications are considered; the subjects using digital resources are not just teachers but also students, student teachers and student teacher educators. Issues raised in the sections include individual and collective use of resources, the adaptation of these resources for specific learning goals and to prepare (pre- and in-service) teachers for the use of digital resources
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
The integration of MathenPoche in college, an instrument for the development of the collaborative work of mathematics teachers in Algeria?
No full textCe travail de recherche se situe à un moment particulier de réforme du système éducatif algérien. Il prend sa source dans les difficultés suscitées par la mise en œuvre de cette réforme, du point de vue, pour l’enseignement des mathématiques, de l’approche par les compétences et de l’intégration des TICe. Il questionne le potentiel des ressources de Sésamath, une association française d’enseignants, pour soutenir le travail des professeurs confrontés à cette réforme.Ancrée dans l’approche documentaire du didactique, la thèse a suivi plus particulièrement trois professeurs d’un collège, à la fois dans leurs classes régulières et dans un atelier de mathématiques, laboratoire d’intégration des ressources de Sésamath.Elle considère particulièrement les systèmes de ressources des enseignants en analysant leur structure et leur évolution, dans la perspective d’une modélisation de ces systèmes. Elle exploite la notion de schème, et notamment d’invariants opératoires, pour décrire l’évolution des connaissances des professeurs.Elle montre comment l’intégration des ressources de Sésamath, dans un milieu arabophone, conduit à développer un travail collectif de sélection, d’adaptation, de traduction et de mise en œuvre de ses ressources. Elle montre comment l’intégration des activités de Sésamath basées sur la résolution de problèmes a soutenu les enseignants dans leur travail de mise en œuvre de la réforme. Elle met en évidence l’intérêt de ces interactions pour l’évolution des connaissances et le développement professionnel des enseignants impliqués.L’étude ouvre des pistes, aussi bien pour la formation des enseignants que pour la modélisation de leur système de ressourcesThis research is situated at a particular moment of reform of the Algerian educational system. It originates from the difficulties of implementing this reform from a point of view, for mathematics education, of the competency-based approach and the integration of ICT. It questions the potential of the resources of Sésamath, a French association of teachers, for supporting the work of teachers facing this reform.Anchored in the documentary approach to didactics, the PhD followed in particular three teachers from a college, both in their regular classes and in a mathematics workshop, the Sésamath resource integration laboratory.It particularly considers teacher resource systems by analyzing their structure and evolution, aiming to modelling these systems. It exploits the notion of scheme, and especially operational invariants, to describe the evolution of teachers' knowledge.It shows how the integration of Sésamath's resources, in an Arabic-speaking environment, leads to developing a collective work of selection, adaptation, translation and implementation of these resources. It shows how the integration of problem-based Sésamath activities has supported teachers in their work for implementing the reform. It highlights the value of these interactions for the evolution of knowledge and professional development of the teachers involved.The study opens ways, both for teacher training and for modelling their resource syste
