Evolution of Forms of Representation in a Modelling Activity: A Case Study
Garuti, Rossella; Dapueto, Carlo; Boero, Paolo
International Group for the Psychology of Mathematics Education, Paper presented at the 27th International Group for the Psychology of Mathematics Education Conference Held Jointly with the 25th PME-NA Conference (Honolulu, HI, Jul 13-18, 2003), v2 p413-420
The report describes a mathematical modelling activity of a natural phenomenon (transmission of hereditary characters in a codominance case) using the concept of model as a theoretical instrument. The chosen tool enables us to show how the construction of a link between reality and a model is related to the evolution of the graphical representations adopted by the students. The lack of such evolution may be either an obstacle to the modelling activity or favour an inappropriate adoption of models generally used for other phenomena. Our analysis also compares the resolution processes enacted by students belonging to different educational environments. (Contains 4 figures.) [For complete proceedings, see ED500859.]
