With information retrieval through the use of video screen-capture in mind, this article seeks to present an analysis of language learners' word search activity using an online dictionary prototype while performing a rewording assignment on collocations. Using screen observable parameters, it was possible to measure the effectiveness and efficiency with which learners accomplished this task. The results show successful task completion, in part due to access to the dictionary prototype. The analysis also reveals the variety of look-up paths taken by participants to successfully complete the task. Four dictionary information seeker profiles have been identified according to the relation between learners' scores (the effectiveness measure) and time and effort spent on task completion (the efficiency measure): the "achievers", the "persistent", the "done and gone" and the "in trouble". Our thoughts are provided on three points: the importance of anticipating the task process (as much as its outcome) so as to be able to scaffold it; the distinction to be made (to teach?) between the initial word search process (more critical) and that of looking-up the search results (more flexible, less critical) in the dictionary; finally, the fundamental notions that need to be mastered in lexicology (collocation, synonymy). We have also highlighted the necessity to employ process-oriented analysis methods. |
