Using corpora in teaching vocabulary to advanced EFL learners in a higher education context

Abstract

Abstract This study focuses on the development of lexical competence of tertiary level EFL learners who have reached C1 level according to CEFR during their course of study, but who still have difficulty in recognizing and producing academic words in terms of their correct and appropriate use in various contexts. Following a data-driven learning (DDL) approach within an action research paradigm, this study aims to discover whether corpus investigation makes a difference in students’ vocabulary knowledge and how they react to corpus data in learning vocabulary. To this end, the study was carried out in a listening/speaking course of two C1 level classes in an EFL classroom at an English preparatory school in Higher Education. In one of the classes, conventional lesson materials, and in the other, corpus-based lesson materials were used to teach the selected vocabulary items. The effect of corpus-based lesson materials on vocabulary learning was examined in relation to conventional materials. The data obtained from pre and post-tests showed that although there was a significant increase in students’ scores from pre-test to post-test, corpus use made statistically no significant difference in their scores as compared to the conventional method that had been adopted during the regular course of study based on the contextual guesswork involved in the coursebook. Students’ reactions throughout the implementation of corpus-based materials and the feedback sessions held with the students, shed light on the results and suggested some pedagogical guidelines for using corpora in teaching L2 vocabulary.
