2. Overview wordlists collocation lists online concordancers text analysis software concordancers ParaConc and Collocate web-based exercises data-driven learning materials 3. Wordlists general and specialised Wordlists have been around since before the invention of computers. General wordlists are used for curriculum development, textbook writing etc. Also possible to produce a word list for a reading (or a possibly textbook) 4. Wordlists general Use existing wordlists such as West's General Service List and recent updates. Coxhead's Academic Wordlist. Kilgarriff's Wordlists based on the BNC. 5. Kilgarriff Page 6.

Vocab Profile Tom Cobb's Vocab Profile http://www.lextutor.ca/vp/eng/ 12. Collocation lists More difficult to find use Collocation Dictionary?? Biber's work on lexical bundles Use concordancer or utility to create ngram lists or locate collocations Collocate shown below 13. Concordancers Online concordancer 14. Concordancers 15. Concordancers americancorpus.org 16. Concordancers Using a concordancer in the classroom Corpus as a reference tool query the corpus can you say the government are what is the difference between for instance and for example Tim Johns Data-driven Learning (...caused economic development...) 17. Concordancers text reconstruction exercises 18. Data-driven learning (deductive) 19. Data-driven learning (inductive) 20. Concordance data DDL highlighting/noticing/discovery learning Highlight unexpected (for the learner) distinctions, uses etc. Sequence data to build up knowledge 21. Parallel concordance data Parallel concordance works on translation corpus Students need to have same L1 22. Concordance data issues KWIC format Google effect Data overload Reauthenticating data Sabine Braun includes discourse perspective (Why did the speaker use that form?) 23. Parallel Corpora DDL (CHUJO, Kiyomi) 24. Parallel Corpora DDL (Chujo, Kiyomi) 25. Collocate Software to extract collocations/terms Word search + Span (2 words, 3 words etc.) n-gram (bigram, trigram) list Full extract -- collocations in a corpus 26. Search for analysis (Span = 2) 27. analysis - frequency 28. analysis - t-score 29. analysis - MI 30. Trigram search 31. Trigram -- by freq 32. Trigram -- alphabetical 33. Trigram -- by MI 34. Using batch mode 35.

Resources Site resources corpora and simple concordancer text analysis utilities 55. Text analysis utilities Create frequency lists Text analysis in terms of frequency bands Collocational analysis of texts 56. Corpora Teacher/Author resource Sample corpus -- CSPAE Add other corpora such as MICASE Create various options for searching that make use of corpus annotation 57. Simple searching 58. Aims Create a language learning site Encourage and facilitate use of corpus data Matching exercise (up to 5 columns) Provide access to word lists etc Provide text analysis tools 59. Aims Use traditional exercise types that teachers are familiar with Give examples of creative uses of these standard exercises 60. Thank you
