Rutiga Familjen för elever med dyskalkuli

bild artikelTill ACM SIGACCESS konferensen Conference on Computers and Accessibility in Baltimore, USA, presenterade Lena Pareto följande artikel 2005: Graphical Arithmetic for Learners with Dyscalculia (eftersom artikeln publiceras internationellt, är den på engelska.) Abstrakt: We propose a model for arithmetic, based on graphical representations, to complement the symbolic language of mathematics. The focus is conceptual understanding of arithmetic. We argue that the graphical model supports understanding concepts known to be difficult for learners with dyscalculia, such as number-sense and decimal system. The proposed graphical representation share properties of the decimal system, but is closer to the semantic representation of numbers vital to the number-sense. The model is evaluated with school-children, but needs to be further tested by learners with dyscalculia. » Läs mer

En mikrovärld för att förstå koncept i aritmetik

bild artikelTill EDMEDIA-konferensen World Conference on Educational Multimedia, Hypermedia and Telecommunications in Lugano, Schweiz, presenterade Lena Pareto följande artikel 2004: The Squares Family: A Game and Story based Microworld for Understanding Arithmetic Concepts designed to attract girls (eftersom artikeln publiceras internationellt, är den på engelska.)
Abstrakt: To address the matter of children’s lacking understanding of arithmetic concepts, we have designed an educational environment, a microworld, which we believe stimulate self-regulation and reflective cognition. The microworld is based on an analogical, constructive representation, where mathematical objects and operations are translated into graphical objects and animations. The microworld contains a story, and combined card- and board games. The story is about the Squares Family. It has three purposes: to explain the graphical model; to introduce the games; and to give an understanding of the concepts involved. The purpose of the games is to allow children to use the graphical model and to practice important aspects of arithmetic. The games focus on concepts, not computations, and encourage own discoveries. The combination of a story-based microworld with games shows potential for providing an effective learning environment. The microworld is developed with user-centred design, and there is a prototype in Java. » Läs mer
