La censura nella Francia settecentesca e la figura del colporteur tra realtà e finzione
2015
La censura assume un’importanza fondamentale nella Francia settecentesca se si considera il vistoso aumento dei censori che passa da quarantuno all’inizio del secolo a settantotto alla vigilia della Rivoluzione. Cercando di raggirare i divieti imposti dalla censura, i colporteur ossia i venditori francesi ambulanti di libri eludano la sorveglianza nascondendo sotto il loro mantello sia scritti libertini che libelli politici, vale a dire i libri più amati e contestati dell’epoca, per poi venderli ai clienti piùabbienti. Censorship is of fundamental importance in eighteenth-century France, a fact corroborated by the increase in the number of censors throughout the century: from forty-one in t…
Apprendenti universitari e profili di competenza nella scrittura accademica
2021
Nell'ambito delle ricerche sulle competenze linguistiche degli studenti universitari in Italia, il contributo indaga le pratiche di comunicazione scritta e le relative difficoltà espresse da studenti di un corso di recupero OFA in corsi di laurea triennale. L'indagine è parte di un progetto di rilevazione più ampio ed è stata realizzata somministrando un questionario informatizzato. I dati raccolti permettono di sviluppare alcune riflessioni utili sul profilo linguistico-comunicativo di apprendenti dalle competenze definite "fragili"; la loro autorappresentazione in termini di biografia linguistica; i bisogni linguistico-comunicativi espressi in rapporto ai compiti di scrittura, e il senso …
Investigating the affordances of a flipped mathematics classroom from an activity theoretical perspective
2020
Abstract Flipped Classroom as a pedagogical framework has gained popularity at secondary and tertiary levels of mathematics education, but there is a lack of research based on a solid theoretical foundation. This article considers the flipped mathematics classroom from the perspective of affordances and cultural–historical activity theory. The empirical background is based on semi-structured interview data from eight first-year computer-engineering students following 1 year of flipped classroom teaching. The thematic analysis of the data indicates that the flipped format offers a range of affordances at various levels of the activity system. This article advances research on affordances for…
Recent Nordic research in mathematics education illustrated by examples from NORMA17
2021
A characterization of recent Nordic research in didactics of mathematics is presented based on the 32 research reports from the Nordic and Baltic countries in the proceedings from NORMA17 (The eighth Nordic conference on didactics of mathematics). Recent Nordic research in didactics of mathematics is observed from several aspects such as choice of problem, theory, method, result, and target for the message. The analyses of the papers on different levels and from a manifold of perspectives build up an image of what Nordic research in DM (didactics of mathematics) contains and represents currently. The closeness and cooperation between researchers in the Nordic countries is characteristic as …
Reasoning with paper and pencil: The role of inscriptions in student learning of geometric series
2009
The purpose of this article is to analyse how students use inscriptions as tools for thinking and learning in mathematical problem-solving activities. The empirical context is that of learning about geometric series in a small group setting. What has been analysed is how students made use of inscriptions, self-made as well as those provided by text books and teachers, and the role these inscriptions played in the coordination of students’ learning/communication. Through the use of inscriptions (made on the chalkboard and with paper and pencil), the students externalised their thinking while engaging in mathematical reasoning on the topic of geometric series. The inscriptions were significan…
Reforming the Teaching and Learning of Foundational Mathematics Courses: An Investigation into the Status Quo of Teaching, Feedback Delivery, and Ass…
2022
Several universities are witnessing an increase in students’ enrolment in mathematics-intensive programmes over the last decades. This increase has come with the price of high failure rates in foundational mathematics courses, which poses challenges to mathematics teaching and learning in higher education. It is therefore inevitable, for some universities, to transform the teaching and learning of mathematics to more student-centred approaches that engage the students mathematically and enhance their success rates. We approach this transformative effort by investigating students’ perception of teaching, feedback, and assessment as a first step in reforming the teaching of a firs…
Third grade students’ multimodal mathematical reasoning when collaboratively solving combinatorial problems in small groups
2022
The aim of this study is to investigate Norwegian primary school students’ multimodal mathematical reasoning when solving combinatorial problems. The data collection took place in four small groups of altogether thirteen 8–9 years old third-graders. Our study shows a variety of approaches used to solve the given combinatorial problems, such as count-all and grouping. These approaches were characterized by the students’ use of inscriptions that displayed all combinations and inscriptions that did not display all combinations. Moreover, the students used gestures such as pointing and sliding. The students’ multimodal reasoning was characterized by the ways their utterances, inscriptions, and …
Qualities of mathematical discourses in kindergartens
2020
AbstractIn this study we investigated qualities of the mathematical discourse in four kindergarten classes in which kindergarten teachers and 5-year-old children engaged in mathematical learning activities. We analysed differences in the mathematical discourses in two experimental kindergarten classes and two control kindergarten classes, in a research and development project. The overarching research question guiding our study was as follows: what characterises the mathematical discourse unfolding in kindergarten classes? In our study we drew on the theoretical framework Mathematical Discourse in Instruction coined by Adler and Ronda, as we quantified the collected qualitative data. Our an…
Grade 8 students appropriating Sankey diagrams: The first cycle in an educational design research
2022
Many students do not experience usefulness in mathematics. To address this problem, we offered them a mathematical tool, Sankey diagrams, which is a flow chart appearing in news media to visualize social, industrial or environmental processes. We carried out an Educational Design Research (EDR) to develop and evaluate lesson materials about contextualized Sankey diagrams. We tested these materials with a class of grade 8 students and evaluated these on the feasibility of students’ appropriation of the diagrams. In the lesson, we observed how students were able to read the Sankey diagrams, liked the societal processes visualized, yet did not fully grasp their mathematical properties. However…
Abstraction and embodiment: exploring the process of grasping a general
2022
AbstractThis paper reports from a case study which explores kindergarten children’s mathematical abstraction in a teaching–learning activity about reflection symmetry. From a dialectical perspective, abstraction is here conceived as a process, as a genuine part of human activity, where the learner establishes “a point of view from which the concrete can be seen as meaningfully related” (van Oers & Poland Mathematics Education Research Journal, 19(2), 10–22, 2007, p. 13–14). A cultural-historical semiotic perspective to embodiment is used to explore the characteristics of kindergarten children’s mathematical abstraction. In the selected segment, two 5-year-old boys explore the concept of…
