Charting the microworld territory: the placing of theoretical signposts
L. Healy. presented at the Symposium on the Occasion of the 100th Anniversary of ICMI, Rome, 5–8 March 2008, (2008)
In this contribution, I intend to focus on the concept of computer microworlds for mathematics learning and, in particular, evolutions in the theoretical perspectives associated with this concept that have emerged within the ICMI community between two moments in its history: the dissemination of the microworld vision in Mindstorms (Papert, 1980) and Papert's plenary lecture at the 17th ICMI study conference, Digital technologies and mathematics teaching and learning: Rethinking the terrain, in December, 2006. Developing ideas about three issues in particular will be considered: reciprocal relationships between mathematical
infrastructures, technology and thinking; the omnipresence of the perceptuo-motor activity in mathematical thinking and learning; and the influence of innovative means of representational and communication on the affective as well as the cognitive dimension.
