This master's research aimed at the designing of corpus-based activities in English, focusing on the development of the oral comprehension for students at levels A2 and B1. To that end, Corpus linguistics was used as a theoretical-methodological apparatus, and the activities were applied in a mini-course of 12 hours taught at a higher education institution in the northwest of the state of São Paulo. The participating students were in the last year of their undergraduate studies and upon finishing the course they have the opportunity to apply for the international proficiency exam TOEFL. The need for this research came after the mapping of Brazilian students’ level of English revealed an insufficient proficiency to follow academic activities in universities abroad (ABREU LIMA, MORAES FILHO, 2016). As a research methodology, we used the Antconc® program as a tool to perform lexical analyzes and descriptions. The corpus of study for this research was compiled from the transcripts of 71 lectures taken from the TED website (www.ted.com) and 56 transcripts of the TED-ED website animations (https://ed.ted.com/). From the data obtained through the analysis of the corpus of study, activities focused on listening comprehension in English were proposed and then applied to students. As a theoretical basis, we followed the concepts of English for Academic Purposes (FLOWERDEW, 2001, CHARLES, 2013, HYLAND, 2006), Corpus Linguistics (CHARLES, 2012, MCENERY, XIAO, 2011, BERBER SARDINHA, 2010); and conceptions about Oral Comprehension (ROST, 2011; FLOWERDEW, MILLER, 2005; GOH 2003, 2012; MCCARTHY, 1998). The results obtained in this research are intended to improve the lexical knowledge of the students in English. We also hope that this study may highlight the importance of Corpus Linguistics for language teaching and learning, as well as the relevance of corpus-based materials.
