PICTURES, GESTURES AND DISCOURSES: A CASE STUDY WITH KINDERGARTEN STUDENTS DISCOVERING LEGO BRICKS
The awareness of the importance to look, through a mathematical lens, to the children drawings, gestures and discourses, considering them as diagnostic tools for the mathematics competences, stays at the base of this contribution. It discusses a didactic experience conducted in a Kindergarten (students 5 or 6 years old) in which we asked children to represent and discus a Lego block with a drawing and speech, observed from different prospective. The discussed results seem to us interesting both for researchers in Mathematics Education and for Kindergarten teachers who want to deepen the role of drawing and gestures as an expressive and diagnostic forms to analyze students’ knowledge, abilit…
Drawings, Gestures and Discourses: A Case Study with Kindergarten Students Discovering Lego Bricks
This paper presents a study aimed at investigating the didactic potentiality of the use of an artefact, useful to construct mathematical meanings concerning the coordination of different points of view, in the observation of a real object/toy. In our view, the process of meaning construction can be fostered by the use of adequate artefacts, but it requires a teaching/learning model, which explicitly takes care of the evolution of meanings, from those personal, emerging through the activities, to the mathematical ones, aims of the teaching intervention. The main hypothesis of this study is that the alternation between different semiotic systems, graphical system, verbal system and system of …
Il numero naturale nei suoi aspetti cardinale, ordinale e ricorsivo: giochi e artefatti in sinergia per la scuola primaria
Il presente lavoro di ricerca e sperimentazione riguarda l’introduzione del concetto di numero naturale e punta alla costruzione di una prima idea dei suoi diversi aspetti, in una prospettiva di curricolo verticale. Attraverso la sinergia di tre artefatti e con il gioco si è favorita la costruzione del ‘senso’ di numero naturale, nei suoi tre aspetti cardinale, ordinale e ricorsivo. Il presente percorso, progettato sulla base della teoria della Mediazione Semiotica e della sinergia tra artefatti, ha avuto come obiettivo principale quello di costruire il concetto in senso globale di numero naturale attraverso la realizzazione della linea dei numeri naturali passando da un’idea intuitiva leg…
