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

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

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.
