<p><strong>R&eacute;sum&eacute;</strong>&nbsp;:&nbsp;Dans cette contribution, nous allons analyser les b&eacute;n&eacute;fices&nbsp;de la mise en place d&rsquo;une s&eacute;quence exp&eacute;rimentale s&rsquo;articulant autour de l&rsquo;&eacute;nonciation dans les avant-textes sur l&rsquo;am&eacute;lioration des &eacute;crits scolaires en FLE. Plus pr&eacute;cis&eacute;ment, elle rend compte d&rsquo;une analyse de 40 textes r&eacute;dig&eacute;s en deux versions (brouillon et texte final) par des &eacute;l&egrave;ves alg&eacute;riens inscrits en 1&egrave;re ann&eacute;e secondaire. Nous nous attacherons &agrave; d&eacute;crypter les indices et les traces (suppressions, ajouts, d&eacute;placements, remplacements) qui renseignent sur la mani&egrave;re dont se m&eacute;tamorphose le texte mettant le scripteur en conflit entre le vouloir dire et les difficult&eacute;s de la langue &eacute;crite. Nous nous int&eacute;resserons aussi aux traces &eacute;valuatives de l&rsquo;enseignante observ&eacute;e et montrerons leurs effets sur les comportements de scripteurs et leur prise en compte lors de la r&eacute;&eacute;criture de leurs avant-textes.</p> <p><strong>Mots-cl&eacute;s&nbsp;:</strong> <em>avant-texte, &eacute;nonciation, trace, &eacute;valuation, FLE</em></p> <p><strong>Abstract</strong>&nbsp;:&nbsp;In this contribution, we will analyze the effect of the establishment of an experimental sequence based on the statement in the foreword on the improvement of school writing in FLE. More specifically, it reports on an analysis of 40 texts written in two versions (draft and final text) by Algerian students enrolled in 1st year secondary. We will endeavor to decipher the indices and traces (deletions, additions, displacements, replacements) which provide information on the way in which the text is metamorphosed putting the writer in conflict between the meaning and the difficulties of the written language. We will also be interested in the evaluative traces of the observed teacher and will show their effects on the behavior of scriptwriters and their consideration when rewriting their pre-texts.</p> <p><strong>Keywords&nbsp;:</strong> <em>foreword, enonciation, trace, evaluation, french as a foreign language</em></p>
