Learner corpora and English language teaching Sylviane Granger (Louvain, Belgium) The concept of using native corpora in foreign language teaching has, for some years now, been gaining increasingly widespread acceptance. Indeed it is this concept which lies at the heart of the biannual TALC conferences, of which this is the fourth. The concept of using computer learner corpora (CLC) for teaching purposes is a much more recent one, however, and one which the FLT community has not yet had time to fully assimilate. In my talk I aim to take stock of CLC-based research, highlighting both the work that has already been accomplished and the largely unexplored potential of the field. In the first section I will define learner corpora and discuss their advantages over other types of data used by SLA researchers and FLT specialists. In particular, I will stress the need to adopt strict design criteria for data collection and describe the most useful methods of analysis. In the second section I will draw up an inventory of the FLT fields which stand to benefit from CLC-based research, focusing mainly on the following three areas: 1) curriculum design: use of CLC for selecting and sequencing what needs to be taught (Mark 1998, Meunier 2000) 2) materials design: use of CLC to improve FLT tools: ‘traditional’ grammars and dictionaries (Longman Essential Activator); web-based materials and CALL programs (Allan forthcoming; Milton 1998; Menzel et al 2000) 3) classroom methodology: use of CLC for data-driven learning (Granger & Tribble 1998) and learning-based exercises (Seidlhofer forthcoming) In my conclusion I will highlight the potential of micro learner corpora compiled by the learners’ own teachers. Analysing this in-house material with text retrieval and error tagging software (Dagneaux et al. 1998) will enable teachers to gain a much more fine grained knowledge of their learners’ difficulties and adapt their teaching accordingly. In view of teachers’ overall lack of experience in corpus research – itself due to the absence of corpus modules in most teacher training programmes –, this work should result from close collaboration between corpus linguists, FLT specialists and teachers.
