While still at kindergarten, many children who possess some degree of phonemic awareness and are familiar with a few letters spontaneously begin to invent writing in which they use conventional letters to represent some of the sounds in words. Ferreiro (1984, 1988) and Ferreiro and Teberosky (1986) were among the first researchers to study children's early ideas about written language, prior to formal education. Their work suggests that children's knowledge of written language evolves along a path over the course of which children think about the nature of writing and build up conceptual hypotheses that reflect an active reconstruction of the logic of the units that are represented by written language.This evolutionary path has been identified for a wide range of languages, including French (Besse, 1996;Chauveau & Rogovas-Chauveau, 1994;Fijalkow, 1993), Portuguese (Alves Martins, 1993), Italian (Pontecorvo & Orsolini, 1996), Hebrew (Tolchinsky, 1995 and English (Sulzby, 1989). Albeit there are some differences in the manner in which these authors define the number and characteristics of the levels of written language development, there are certain similarities in their positions.Generically speaking, in their attempts at writing children begin by using sequences of letters that imitate words by allocating them a communicational meaning. In this level children
