Students are expected to write complex text genres in higher education contexts. Such complexity stems not only from the nature of the knowledge they convey but also from the norms and conventions adopted by the academic communities that use such texts. Among those genres, the dissertation seems particularly complex, considering both the set of problems related to its configuration (structure, language, norms of reference), and the factors that constrain its production (methodological procedures, student/supervisor relationship, time management, institutional constraints, individual nature of the writing process). The present study seeks to identify and analyze (i) students’ perspectives and representations of the dissertation writing process, and (ii) the problems that arise in the writing process. It is based on semi-structured interviews with students, at three different universities in the North of Portugal, who recently completed their dissertations in Humanities, Education and Engineering. The analysis is based on the assumption that writing a dissertation involves not only cognitive, linguistic and social dimensions, but also emotional aspects that can condition it decisively.

In Portuguese higher education, teachers from different scientific areas recognize that their students have difficulties with writing. Nevertheless, preparing students for academic writing is not a priority and any intervention depends more on the interest of particular teachers than on any institutional policy. The development of a more institutional approach to academic writing in Portugal will imply a deeper knowledge of the multifaceted reality of the students’ situation, involving identification of their own perceptions of their writing processes and of the academic writing practices they are subject to. This is the aim of our study, based on 1150 students’ answers to a questionnaire about literacy practices in Portuguese higher education.Our results show that students seem to be conscious of the procedural nature of writing and of the role and importance of planning, composing and reviewing in the course of their writing processes. As for their perceptions about institutional interventions aimed at fostering writing abilities and teacher feedback on their written work, the answers to the questionnaire allow us to conclude that such support is not frequently offered. There are, however, some differences in the way these issues are considered across the various fields of study.

In this article we analyse Portuguese postgraduate students’ problems and difficulties when performing written tasks in the context of postgraduate programmes. The data presented are the result of a study based on two different data collection procedures: a) the analysis of students’ written work, organised in a portfolio; b) a questionnaire focussing on the difficulties encountered when performing different tasks involving writing: note-taking; planning a text; writing and editing a text (a literature review); and referencing and quoting according to a reference style (APA). The analysis of students' work revealed problems and difficulties in different areas, namely with selecting information, planning the text, and writing the literature review using academic writing conventions. When asked about the reasons for those problems, students often referred to the difference between the literacy tasks they were used to performing in their undergraduate studies and those that they are requested to develop at the postgraduate level. These differences seem particularly relevant when those tasks are related to assessment practices. At undergraduate level, assessment is often based on examinations while at postgraduate level, it is more dependent on the production of other genres such as literature reviews or essays.
