This research is a theoretical-exploratory study fo e- learning and the teaching and learning of writing in the first language on-line. A critical analysis of existing textual production courses offered in the internet have revealed negligence of language practices that involve interactional practices and that place meaning construction in interaction, rather than in the text. Based on a needs analysis and on the profile of the target group, the purpose of this study is to plan and design an on-line textual production course in L1 that would fill such gap and that would focus not only on content, but on language practices embodied by socio-interactional principles such as retextualization from orality to writing and dialogism. To do so, it reviews the literature on e-learnig and the teaching-learning of writing, analyzes existing on-line writing courses, and conducts field researched by observing and collecting data from a class of text production at PUC-Rio, majoring in Letters. The data for the needs analysis were gathered by means in class observation, interview with the professor, and one questionaire.
