Goals for this presentation

To provide some reasons for using
corpora or corpus research - why

To show how to use corpus research and
corpora in the classroom - examples

Present some guidelines & resources

Why use a corpus to teach?
A corpus can…
provide insights into language use where
intuitions often fail – or worse, give us the
wrong information.
be a source of language teaching materials.
provide students with hands-on
opportunities for language learning.

What is a corpus?
A large, principled collection of natural texts
Analyzed using both automatic and
interactive computer techniques
Depends on both quantitative and qualitative
analytical techniques
(Biber, Conrad & Reppen 1998)

Four ways to use corpora & corpus
linguistics in the classroom

Inform the syllabus

Create materials/activities

Create specialized corpora

Use online resources
©2010 Randi Reppen
Ways to use corpus linguistics for
language instruction:
Inform the syllabus
Teachers can use information from corpus
research to help inform decisions about
which features to present and how much
time to spend on various features.

An example from word formation

What do we know about affixes?

Suffixes are more productive than prefixes

Not all suffixes are equally productive
when it comes to academic words.

The six most productive suffixes are:
-tion, -ity, -er, -ness, -ism, and –ment
(Biber et al, 1999)
©2010 Randi Reppen
Example activity 1
Give students a copy of a page from a textbook
or a journal article in the case of graduate
students.
 Then, ask students to circle all of the nouns that
they find with any of the six suffixes listed above.
 Discuss the words: Look how words may change
from nouns to verbs when the suffixes are added
paint  painter = verb  noun; or noun  noun
govern  government = verb  noun


Using corpora to create materials
for language instruction
Teachers can use corpora to create a
variety of materials.
Word frequency lists from readings
 Models of language use & role play actual
dialogues
 Practice activities & testing

Service encounters at a coffee shop
1: Hi.
2: Hi. Could I get small regular coffee, with uh, hazelnut?
1: Here's a large cup, because we ran out of the small ones.
2: OK. Thank you.
1: Thank you.
2: No problem.
1: Have a nice day.
2: You too.
1: Hi.
2: I want just the onion bagel, and could I, um, have cream
cheese? And a small lemon lime.
1: Thank you.
2: Thank you.
1: You have a nice day.
2: Thanks.

Create specialized corpora
For example:
a corpus of business texts;
 a corpus of engineering texts;
 a corpus from class readings;
 a corpus from student papers.

Total number of words = 25,232

Content words are often:
Typographically
enhanced
Defined in the text
Easily explainable
Discipline specific
Conceptually related to other
content words
©2010 Randi Reppen
Academic words are:
 Almost
invisible
 Often polysemous
 Often used in a variety of contexts
©2010 Randi Reppen
Uses of specialized corpora
Identify unfamiliar words
 Identify high frequency words
 Use KWICS to generate class activities
 Identify word senses
 Practice inferencing strategies


 Verb morphology
 Subject/verb agreement

Site evaluation checklist:






How do I want to use this site?
Does the site match my purposes/ goals?
Does the site do what it says it will do?
Is the site stable, or does it crash/freeze my
computer?
Are the instructions clear and easy to follow?
(Esp. if learners will be using the site)
If there is a user fee, does the fee match the use?

Checklist for developing activities






Know what you want to teach!
Select the best corpus resource for your lesson.
Explore the corpus completely for the point you
want to teach.
Have complete and easy to follow directions
Provide a variety of ways for interacting with the
materials.
If you are using computers ALWAYS have a
alternative plan or activity.

Teachers can use corpora to create
materials & activities
Word frequency lists from readings
 Models of language use & role play actual
dialogues
 Practice activities & testing
 Specialized corpora
 Use online corpora


Learners can interact with corpora to:
Learn vocabulary;
 Explore extended collocations;
 Compare against model texts;
 Discover patterns of use.

