introduction
Introduction
  • The usefulness of corpora in language pedagogy is widely recognised.
  • But there is a need for pedagogically relevant corpora, reflected e.g. in initiatives to create 'ad-hoc' corpora in pedagogical contexts.
  • The creation of pedagogically relevant corpora raises challenges for corpus design.
  • Past and current initiatives have largely focussed on written corpora; spoken discourse is becoming more important in pedagogical contexts.
  • The creation of pedagogically relevant spokencorpora raises additional challenges for corpus design.
the challenges 1
CORPUS DESIGNTraditional reference corpora (content, size, data format,transcription, annotation, query)

CORPUS EXPLOITATIONData-Driven Learning (focus on non-linear reading: concordances and co-texts)

The challenges (1)
  • Corpora contain textual records of discourse; their interpretation requires (re-)contextualisation.
  • Learners may have difficulties analysing corpus data; they require pedagogical mediation.
  • Pedagogical corpus uses differ from linguistic description; this requires e.g. pedagogically motivated query options.
  • Corpora need to be integrated with curricula; this requires e.g. complementarity of content and effective delivery.

Do not fully support pedagogical requirements.

the challenges 2
CORPUS DESIGNTraditionally: representation in written format

CORPUS EXPLOITATIONWork with text-only data and e.g. conversational markup

The challenges (2)
  • Spoken discourse is more dependent on shared physical contexts.
  • It is adjusted to aural and online perception (e.g. chunking)
  • It is affected by limitations of processing capacity (false starts, repair).
  • It is marked by accents.
  • It is multimodal.

Again, this does not fully support pedagogical requirements.

requirements
Requirements
  • Format: multimedia to retain multimodal character of spoken language
  • Content: complementary with curriculum topics, more coherence than in traditional corpora
  • Pedagogically motivated transcription, annotation and alignment (transcript-video)
  • Combination of query methods: text-based exploration and application of corpus techniques
  • Pedagogical enrichment of corpora with complementary resources (e.g. exercises, explanations)
  • Effective delivery of corpora and additional resources to learners/teachers
corpus creation 1
ELISA

Professional English

Accounts of professional life

Different varieties

SACODEYL

7 European languages

Youth language corpora

Speakers 13-15 and 16-18

Corpus creation (1)
  • Examples: ELISA and SACODEYL
  • Interview format
  • Video clips with transcript
  • Communicatively relevant topics, e.g. in SACODEYL topics outlined in the Common European Framework
  • Elicitation process: briefing informants and prompting them during the interview, ensuring naturally flowing discourse

corpus query
Corpus query
  • Query options will support text- and corpus-based exploration and include e.g.
    • Easy access to entire interviews
    • A topic index supporting the analysis of similar sections across interviews ("topic concordances")
    • Other indices based on the annotation categories
    • Ready-made data (e.g. frequency lists of each interview; selective concordances)
    • A concordancer for extended/advanced search; adapted to pedagogical requirements
pedagogical enrichment
Pedagogical enrichment
  • The corpora will be enriched with prototypical learning activities.
  • These will focus on one interview section or one interview as a whole or sections across interviews…
  • They will include e.g.
    • linguistic and cultural explanations and exercises(form-focussed as well as communication-oriented),
    • (listening) comprehension and production tasks,
    • explorative tasks (concordance-based as well as interview-based).
  • Use of authoring tool Telos Language Partner to create learning packages with ranges of activities.
corpus delivery
Corpus delivery
  • Effective delivery as a further prerequisite for integration into curriculum
  • In SACODEYL, use of Moodle learning platform, giving access to:
    • Corpora (query interfaces)
    • Resources created in the project (different types of learning activities)
    • Resources created by future corpus users
summary
Summary
  • Method outlined is transferable to other pedagogical contexts, topics, languages
  • Method helps to use corpora more efficiently in pedagogical contexts – from sporadically used resource to systematic exploitation
  • Corpus creation complies with standards to facilitate reuse of corpora for other contexts (research)
