Using grammar to create a good relationship

Michael McCarthy
This was the title of a recent webinar hosted by Cambridge English Teacher and presented by Michael McCarthy.  He should have been joined by Anne O'Keefe, but unfortunately technical issues meant she was unable to connect.  What follows is a summary of what Michael had to say.

Grammar is more than just a set of abstract rules - it can be used to create appropriate relationships:
  • Forms of address (sir, madam, mate, etc.)
  • Formal vocabulary (e.g. we wish to advise you....)
  • Hedging and vagueness (e.g. a bit hungry, hungry-ish)
  • Indirectness (e.g. one shouldn't worry, it is hoped that....)
  • Using tense, aspect and modality (e.g. I wondered..., I should be grateful...)
  • Involvement strategies/use of pronouns - ways of making the person you're talking to feel more part of the topic of conversation
  • Ellipsis (e.g. want some coffee? you ready?)
Corpus evidence
  • Cambridge English Corpus - 2 billion words
  • CANCODE Spoken Corpus - 5 million words (mostly informal speech)
  • Cambridge Learner Corpus - 5 million words
  • CANBEC Spoken Business English Corpus - 1 million words
  • CLAS Spoken Professional/Academic Corpus - 1 million words taken from a hotel management context in Ireland
These corpora give us the evidence to understand how grammar is used.  Where grammar gives us choices, the choice you make affects how your spoken or written word is received.  Look at this example which goes from direct to less direct and, therefore, more polite:
  • Where's the key?
  • I hope you've got the key.
  • I was hoping you had the key.
Or this example:
  • I wonder if you can help me?
  • I'm wondering if you could help me?
  • I was wondering if you could help me?
All of these sentences are grammatically correct, but small changes affect the degree of politeness.

Some verbs are more polite and less direct when used in the continuous form (present or past).  For example:
  • Are you needing something?
  • I was wondering if I could ask you a question?
  • I was hoping you'd come to visit.
  • We were thinking we should finish this by Friday.
Look at this example in context:

 
or this one:
Customers and servers work hard from the beginning to set an appropriate relationship.
 
Use of pronouns (we versus you)
 
Choice of pronouns can create closeness or distance.  In this example, the salesperson uses 'you' and 'your' to make the customer feel involved - almost as if he owns the item already:
 

In this example, we see the pronoun of involvement used in an academic setting - a hotel and catering college:
Modality
 
Modality can express degrees of formality and degrees of imposition.
 
Looking at corpora for incidences of 'can I ...?' and 'could I ...?', we see a huge difference in the number of times these are used in spoken informal English.  We can also see that there are no examples in Cancode of 'might I ...?' being used.  Corpus enables us to see the degree of formality these forms express, but also in what context they're used.
 
Ellipsis
 
Ellipsis, the non-use of items normally considered obligatory, in conversation reinforces directness and closeness.  For example:
To conclude:
 
Incorrect choices can project the wrong relationship in terms of the degrees of directness and imposition.  The grammar discussed in this webinar is all very common and is normally taught at low levels, but we need to look at it again at higher levels to explore the subtleties.  Good teaching materials should include this grammar of choice to enable students to communicate effectively.

Corpora and the advanced level: problems and prospects

Michael McCarthy
This was the title of a recent Cambridge English Teacher webinar presented by Michael McCarthy. What follows is a summary of what he had to say.

Key issues at the advanced level

Beginner level English is easy.  Students need to know basic vocabulary and grammar.  Once you get up to upper-intermediate and advanced levels (B2 - C1 - C2), though, it gets difficult!  There really isn't much consensus about what we should teach at advanced level, but evidence from corpus can help us decide.

Once you get beyond the 2000 or so most common words, vocabulary becomes a vast catalogue of low-frequency items, so how do we know which words to teach?  Grammar loses its sense of progression and tends to be a rag-bag of difficult and arcane items.  How do we bring a sense of usefulness to the grammar at this level?

Assessment targets become more difficult to distinguish at higher levels.  For example, fluency:

  • B2 - fluent
  • C1 - very fluent
  • C2 - extremely fluent
What does this mean?  How do we judge it?  Lower level learners get lots of opportunities to show their level in exams.  Higher level students perhaps don't.

Vocabulary

The English Profile programme uses corpora to answer questions about vocabulary and grammar.  It is available online here.

The main problem is, if we just teach and learn new words as they come up, we find that these words give back less and less.  The first words we learn give great text coverage, but as we learn more words, the return reduces as they are less common.

At more advanced levels, collocations and language chunks become much more prominent.  The same words appear in more and different combinations. Register, connotation and style become more important.  There is more specialised vocabulary and subtle, evaluative nuances of adjectives, for example, need to be explained.  There is also a growth in domain-specificity - vocabulary particular to specific disciplines.

There is evidence of possible slowdown and attrition at higher levels, too. The pace of learning slows and students may even reach a plateau and stop developing completely.

The English Vocabulary Profile gives labels for words and phrases and can be browsed by CEFR level or by the vocabulary item itself.  This helps teachers to know what vocabulary is most useful for students to learn at a particular level. It also gives students a progression if they focus on the words they need to know at each level.

Grammatical issues

At higher levels we can focus on:
  • New or not typically taught functions for known forms.  For example, we can teach the uses of present perfect that we haven't had time to cover at lower levels.
  • Low-frequency patterns - structures that are still used by native or proficient speakers, but not often.
  • Patterns that underlie academic success - grammatical structures that help students to score well in exams.
Example - Future Perfect (Continuous)

The common usage which we teach at intermediate level is - At the end of this year, I will have been living in Vietnam for three years.  However, if we look at corpus, we can find another common use for this tense:

You'll have heard about the terrible earthquake.
You'll have been given a handout.

Here, future perfect is used to make assumptions about the present - things that have already happened!

Look at these examples from the corpus of present perfect continuous being used in the same way:
At higher levels, we should find and teach examples like this.  We need to show our students different functions of grammar which is already known. They will be able to use them in their speaking and writing, and recognise the meaning when they hear or read them.

Example - Subjunctive Patterns

Here, we are talking about instances where the verb is always in the base form.  For example,

They insist that he wear his uniform at all times.
......their insistence that he wear his uniform ......
......is important that he wear his uniform .......

verb/noun/adjective + that + subject + base form of the verb

We can look at a corpus and see how the subjunctive is used.  Although it's not so common, it's useful and students think they're making progress when they learn about it.

Look at these examples taken from English Profile:



























We can teach these structures as a piece of grammar and link it with vocabulary by using English Profile.

The power of the corpus is that it can give coherence and purpose to syllabi at higher levels.

Example - Nominalisation

Here, we are talking about the process of turning a verb into a noun.  

We fly at seven.    >        Our flight is at seven. 
Mr X donated Y.    >        Mr X made a donation of Y.

It is seen as a sign of good academic writing.  This can be confirmed by looking at the Cambridge Learner Corpus which takes examples from students' work and researches what grammar structures and vocabulary attract the highest marks.

Example - Modality

Analysis of success at higher levels indicates that the use of adverbs after modal verbs is good!


Conclusion

The corpus is relevant and current - results from it can be put straight into teaching materials.

Ask:

  • What is it that remains to be learned at higher levels?
  • How can the corpus help us to decide what must be taught and how to teach it?
Students can't learn every word in the English language, so tell them to concentrate on the words that interest them.  By reading texts that interest them, their general vocabulary will improve and they will make progress - FACT!!
