Abstract. With this article we hope to contribute towards the definition of the field of the Didactics of Writing in Portugal, an area which has been developing, essentially, since the mid 90s, in order to define both the problems surrounding research in this area, as well as the contents used in the teaching and learning of writing which result from the former. It is not our objective to go into detail concerning the state of the art in this field in Portugal; our purpose is to present the main perspectives which have emerged throughout recent years, defining an area which is currently beginning to show signs of greater definition. Thus, we shall attempt to provide some answers to the following research questions: what context encouraged the emergence of this area of study, how has the configuration of this field been perceived, what theoretical references sustain the empirical research underlying this development? In order to answer these research questions, three analysis axes were considered which, from our viewpoint, aggregate the research themes within the Didactics of Writing. In the first analysis axis, the objective is to present a set of findings centred on the processes underlying students' activity of writing texts, focusing more specifically on the development of textual revision competence. In the second analysis axis, the aim is to validate the emergence of a research line which is pertinent to the Didactics of Writing, focusing on the relevance of teachers and students' relationship with writing. In the third analysis axis, we present an illustrative layout of a research line which demonstrates the relevance of understanding the teacher's action when working with text genres. Subsequently, we shall demonstrate the way in which these three axes can configure a referential in the definition of a global teaching and learning model for writing, capable of providing guidelines for classroom action. Finally, we shall discuss some research directions which sustain the validity of this model. Tanja Janssen] TITEL. Bijdragen aan de afbakening van het terrein van de schrijfdidactiek in L1. Onderzoek en praktijk in de eerste fasen van het basisonderwijs. SAMENVATTING. Met dit artikel hopen we bij te dragen aan de afbakening van het terrein van de schrijfdidactiek in Portugal, een terrein dat in wezen in ontwikkeling is sinds het midden van de jaren '90. Zowel de problemen rond onderzoek op dit terrein, als de inhoud van het schrijfonderwijs dat daaruit voortkwam komen aan de orde. Het is niet ons doel om in detail "the state of the art" op dit terrein in Portugal te beschrijven, maar om de belangrijkste perspectieven die zich de afgelopen jaren duidelijker zijn gaan aftekenen, te presenteren. We zullen pogen antwoorden te geven op de volgende onderzoeksvragen: welke context bevorderde de opkomst van dit onderzoeksterrein, hoe wordt het terrein vorm gegeven en hoe kijkt men daar tegenaan, welke theoretische verwijzingen onderbouwen het empirische onderzoek dat aan deze ontwikkeling ten grondslag ligt? Om de...
