摘要：

I will analyse the individual and collective activities of fourth grade students while trying to explain a schoolfellow's mistake in the use of a geometrical schema (shared by the class) of the sunshadows phenomenon. The study aims at detecting productive links between context-related argumentation, mathematical modelling (here concerning sunshadows) and conceptualization (inclination of a straight line to a plane), as well as discussing their relevance for mathematics education.
