Iteration is a fundamental concept in computer sciences which allows the construction of algorithms requiring the repetition of a large number or of a prior unspecified number of identical actions. The object of the present paper is to study the construction process of an iteration by middle-school pupils (age 11-16) who have never been taught programming. The pupils were placed in an experimental situation where they were confronted with the task of writing a programme for an imaginary robot in order to find a solution to a problem specifically based on iteration. The analysis of the observed strategies is carried out with reference to iteration, to the set problem and to the experimental situation.L'itération est une notion informatique d...
