Abstract
In the paper we show, through a hypothetical "conversation" among two pupils and a computer, how it is possible to use the Logo language in interactive way for solving verbal poblems with the top-down method.The interaction man-machine is very simple: it is based on the primitives OUTPUT and TRACE of the Italian version of Logo Commodore and on the particular type of its messages of error.In the paper we present, in an unusual manner, a trace of the work developed with pupils aged 11-12, for a concrete and motivated approach to the analysis of problems and to their decomposition in to subproblems.The theme has been chosen for the importance that this method assumes both in the problem solving and in the approach to the structured programming.
