2. Outline of talk • Corpus analysis in EAP research • Students learning from corpora: Data-driven learning and an alternative • Teachers learning from corpora: Classroom applications

4. 22%

5. Features of 23 JEAP ‘corpus’ papers • Paper types • 18 corpus analyses • Corpus content • 13 writing; 4 speech; one both; journal articles predominant; focus on single soc sci disciplines • Corpus types • mainly expert/ published • Focus of analysis • mainly particular lexical/ grammatical features

9. Corpora as resources for learners: data-driven learning (DDL) DDL: • exposes students to ‘target’ language forms • provides authentic examples • provides information beyond dictionary or grammar • encourages inductive learning • encourages learner autonomy

10. Lee & Swales (2006): DDL “…an exceptional group of students – highly acculturated into the genres of their discourse communities, mostly on the way to their PhDs, eager to perfect their English, possessing of advanced computer skills, and perfectly comfortable with quantitative data.”

11. DDL: some reservations • lack of evidence to link DDL to language improvement • are the outcomes worth the time, effort and money? • it doesn’t suit all students

12. Selecting corpus data for students (as an alternative to DDL) • An example: MBA students’ use of ‘I’ • ‘Research article (RA) corpus’: 120, 000 words • ‘MBA corpus’: essays, 22,000 words

25. Teachers learning from corpora: discovering new information

26. Some nouns have a related adjective ending: • -ic base – basic (not basical) • -ical astrology – astrological (not astrologic) • -ic or –ical analysis – analytic/ analytical

32. -ic or –ical ? ecological and geographical (rather than ecological and geographic) taxonomic and geographic (rather than taxonomic and geographical)

34. Teachers learning from corpora: finding authentic examples catastrophic – risk – event • Premature discontinuation of antiplatelet therapy markedly increases the risk of stent thrombosis, a catastrophic event that frequently leads to MI and/or death. • A final important difference related to the nature of the risk may be that some workplace mortality risks tend to involve sudden, catastrophic events, whereas air pollution-related risks tend to involve longer periods of disease and suffering prior to death.

35. The corpus as a source of authentic examples: catastrophic – risk - event • …risk of a catastrophic event such as… (GS= 16) • …there is always a risk of …. (GS= 4,670) • …such as forest fire… (GS= 616) • …such as forest fire or flood (GS= 1) Into the material: • There is always a risk of a catastrophic event such as forest fire or flood.
