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!!

Teaching vocabulary - an #eltchat summary

This is a summary of the #eltchat held at 12noon BST on Wednesday 19th September, 2012. The full title of the chat was:
'How should we approach vocabulary teaching and learning?  Is there a place for rote learning?  What is the current thinking about it?'
I have to say that I didn't vote for this topic, mainly because it was up against my suggestion of 'first lesson ideas'.  As it turned out, my subject won the vote and was discussed at 3am my time here in Vietnam so I missed it!  Instead, I found myself involved in a very interesting chat session on teaching vocabulary and came away with lots of food for thought.  It was expertly moderated as usual, this week by @Shaunwilden and @theteacherjames. 
 
Rote Learning Vocabulary - the Pros and Cons
 
We began by discussing rote learning and it soon became clear that we had a difference of opinion as to the effectiveness of the method. 

@teflerinha told us that she had had success with rote learning when she was learning Polish and Portuguese, particularly when using small 'crib' cards.  These cards can be created by using quizlet or other similar websites.  She also said that level is relevant - beginners need more rote learning because there is less context available.  @ElkySmith added that rote learning is easier at low levels because of the concrete nature of the vocabulary.  @louisealix68 reminded us that some students prefer rote learning ('musical intelligence') and told us that it had really helped her with German.  @rliberni suggested that rote learning can be made more fun by creating chants, songs and raps.

Personally, I have never had much success with rote learning, either as a learner or a teacher.  This opinion was shared by @cioccas.  @michelleworgan also questioned its long-term effectiveness, especially with YLs.

Several contributors, however, gave the link to an article by Paul Nation on why rote learning works, although it was pointed out that Nation himself admits that, once learned by rote, students have to use the new vocabulary in context in order for it to 'enter deep store'.
 
Clearly, there is a place for rote learning with some students, but it is not ideal for all learning styles.
 
Other Ways of Teaching Vocabulary
 
Most #eltchat participants agreed that we need to keep students engaged in vocabulary learning by finding other teaching methods, rather than just asking them to learn word lists.  Some of what follows has a basis in rote learning, but is much more interesting and effective.

  • Giving students context is vital to help them remember new vocabulary.
  • @rliberni reminded us that translation has a part to play.
  • @LizziePinard advised us to use quizzes and games where possible, bingo and pelmanism, for example.  She suggested that, 'if you increase the depth of processing, the lexis becomes more memorable'.  This can be achieved by getting students to use more than one kind of processing - identifying, manipulating, classifying, etc.
  • Use pictures and diagrams: for example, put house vocabulary into an outline of a house.  Combining vocabulary with visuals is always a powerful way to present and, later, recall vocabulary.
  • Get students to use vocabulary in a personal way to make it more memorable.
  • Give regular vocabulary tests or weekly revision sessions.
  • Get students to create word search puzzles for other classmates to solve.
  • Use mnemonics to make rote learning more fun - all those of us who learned 'the colours of the rainbow' or 'the planets in the Solar System' this way will never forget them! 
  • Favourite games for teaching and revising vocabulary include 'Taboo', 'Outburst', 'Say my Word', 'Blockbusters' and 'Call my Bluff'.
  • Use all of the senses to help students remember new vocabulary - think about the sounds and smells associated with words.
  • Get students to create weekly vocabulary posters which are then displayed on the wall as a permanent visual reminder.  Later in the course, these posters can be used in memory games, sentence building, story telling, etc.
  • Encourage students to read as much as possible in order to increase their vocabulary.
  • Writing is one of the best ways to revise vocabulary.
  • Encourage the use of vocabulary notebooks and urge students to be creative with them - word trees, pictures, use of colour, etc.
  • Get students to prepare wiki pages on a specific topic at home - these can then be referred to both in and out of class.
  • Don't overload students with masses of new vocabulary at the same time - 'small amounts often' is the way forward for @ElkySmith, both when presenting new words and revising what has already been covered in class.
  • Synonym posters in the classroom, which students add to during the course, are a great way to expand vocabulary.  This works just as well with mind maps which can be built on.
  • Co-operative or half crosswords are great for teaching vocabulary.
  • Remember not to limit vocabulary to words - lexical chunks are particularly useful.
  • Make students think about how words behave and not just what they mean.
  • Teach vocabulary through reading texts, where students underline the words they don't know and then use them in their own sentences.
  • Use drama activities - for example, students make up a mime using narrative verbs learned and their classmates have to call them out.
  • Teach students to understand meaning from context when reading and listening.
  • Get students to watch films in English with English subtitles so they are getting the vocabulary through both visual and auditory channels.
  • Use TPR, particularly with YLs, to help memorise directions, body parts, emotions, requests, imperatives, adjectives, etc.
  • Teachers need to remember to reuse new words as much as possible in class - students pick up on this and try to do the same.
  • Use songs, as long as you explain what the lyrics mean!
  • Relate challenging vocabulary to songs or popular films or TV shows.  The example given by @Teachersilvert was using 'Friends' to illustrate 'freak out'.
  • Only teach relevant vocabulary - words and phrases students will need.  Good dictionaries will tell you how frequently a word is used - this online example from the OUP is particularly good: http://oald8.oxfordlearnersdictionaries.com/oxford3000/
  • Have a 'word of the day' for students to use correctly in class (or even a 'chunk of the day').
  • Revise as much as possible.  A good tip is to have a vocabulary bag and use it for constant recycling activities.  This was suggested by @jobethsteel.  I would endorse this - we use them in our department and if a teacher is a few minutes late for class, it's so easy for a colleague to go in and do a quick vocabulary revision exercise using the 'word bag of the week'!!

Conclusion

As with all EFL teaching, there is no 'one size fits all'.  Rote learning has its place, but it doesn't work for all learners (or teachers!).  The key is to use a variety of approaches, tasks and activities in order to provide multiple experiences of, and exposures to, new vocabulary.  Whether you use rote learning or not, students need opportunities to notice new words and lexical chunks as well as situations where they need to use them.
