This research aims at investigating the process of writing and revising academic summaries in grad courses by focusing on fundamental concepts in textual genres and writing process models. We considered how students perform summarization, which linguistic features and production strategies they use the most, which concepts of revision they have, and to what extent these factors influence the text’s quality and effectiveness. Academic writing has proven to be a challenge among university students, who, regardless of their field, seem less and less prepared to cope with the different genres in grad contexts. The academic summary is a genre that stands out in this regard, since it involves mastering a set of basic reading and writing abilities required in the writing of more complex genres. The methodology is based on an analysis of data obtained from a writing activity regarding summary writing carried out with two groups of students and with the use of the Camtasia Studio software. Summaries’ structuring was similar to the source text’s discursive organization. Students used lots of paraphrasing, mainly through synonyms and syntactic modifications. Summarization was characterized by lots of deletions, mostly clauses that are considered accessorial (adjective and adverbial), thus partly reflecting electronic summarization extraction patterns. Generally, propositions that were considered the most relevant matched the source text’s phrasal topics and were more easily recognized when written in direct order and appearing in a predictable position. Revision as a monitored writing process prevailed as a concept, with revision operations being performed during text production.
