Teaching
Vocabulary To Advanced Students: A Lexical
Approach
by Solange Moras, Sao Carlos, Brazil, July 2001
1. ADVANCED STUDENTS
AND THEIR NEEDS
Advanced learners can generally
communicate well, having learnt all the basic structures of the language.
However, they need to broaden their vocabulary to express themselves more
clearly and appropriately in a wide range of situations.
Students might even have a receptive
knowledge of a wider range of vocabulary, which means they can recognise the
item and recognise its meaning. Nevertheless, their productive use of a wide
range of vocabulary is normally limited, and this is one of the areas that need
greater attention. At this stage we are concerned not only with students
understanding the meaning of words, but also being able to use them
appropriately, taking into account factors such as oral / written use of the
language; degree of formality, style and others, which we are going to detail in
Part 2.
2. THE TEACHING
OF VOCABULARY
Traditionally, the teaching of vocabulary
above elementary levels was mostly incidental, limited to presenting new items
as they appeared in reading or sometimes listening texts. This indirect teaching
of vocabulary assumes that vocabulary expansion will happen through the practice
of other language skills, which has been proved not enough to ensure vocabulary
expansion.
Nowadays it is widely accepted that
vocabulary teaching should be part of the syllabus, and taught in a well-planned
and regular basis. Some authors, led by Lewis (1993) argue that vocabulary
should be at the centre of language teaching, because ‘language consists of
grammaticalised lexis, not lexicalised grammar’. We are going to discuss aspects
of the ‘Lexical approach’ in Part 2.
There are several aspects of lexis that
need to be taken into account when teaching vocabulary. The list below is based
on the work of Gairns and Redman (1986):
· Boundaries between conceptual
meaning:
knowing not only what lexis refers to, but also where the boundaries are that
separate it from words of related meaning (e.g. cup, mug,
bowl).
· Polysemy: distinguishing between the various
meaning of a single word form with several but closely related meanings (head:
of a person, of a pin, of an organisation).
· Homonymy: distinguishing between the various
meaning of a single word form which has several meanings which are NOT closely
related ( e.g. a file: used to put papers in or a tool).
· Homophyny:understanding words that have the same
pronunciation but different spellings and meanings (e.g. flour, flower).
· Synonymy: distinguishing between the different
shades of meaning that synonymous words have (e.g. extend, increase,
expand).
· Affective meaning: distinguishing between the
attitudinal and emotional factors (denotation and connotation), which depend on
the speakers attitude or the situation. Socio-cultural associations of lexical
items is another important factor.
· Style, register, dialect:
Being able to
distinguish between different levels of formality, the effect of different
contexts and topics, as well as differences in geographical
variation.
· Translation: awareness of certain differences and
similarities between the native and the foreign language (e.g. false
cognates).
· Chunks of language: multi-word verbs, idioms,
strong and weak collocations, lexical phrases.
· Grammar of vocabulary: learning the rules that enable
students to build up different forms of the word or even different words from
that word (e.g. sleep, slept, sleeping; able, unable;
disability).
· Pronunciation: ability to recognise and reproduce items
in speech.
The
implication of the aspects just mentioned in teaching is that the goals of
vocabulary teaching must be more than simply covering a certain number of words
on a word list. We must use teaching techniques that can help realise this
global concept of what it means to know a lexical item. And we must also go
beyond that, giving learner opportunities to use the items learnt and also
helping them to use effective written storage systems.
2.1. MEMORY AND STORAGE
SYSTEMS
Understanding how our memory works might
help us create more effective ways to teach vocabulary. Research in the area,
cited by Gairns (1986) offers us some insights into this
process.
It
seems that learning new items involve storing them first in our short-term
memory, and afterwards in long-term memory. We do not control this process
consciously but there seems to be some important clues to consider. First,
retention in short-term memory is not effective if the number of chunks of
information exceeds seven. Therefore, this suggests that in a given class we
should not aim at teaching more than this number. However, our long-term memory
can hold any amount of information.
Research also suggests that our ‘mental lexicon’ is highly organised and efficient, and that semantic related items are stored together. Word frequency is another factor that affects storage, as the most frequently used items are easier to retrieve. We can use this information to attempt to facilitate the learning process, by grouping items of vocabulary in semantic fields, such as topics (e.g. types of fruit).
Oxford (1990) suggests memory strategies
to aid learning, and these can be divided into:
· creating mental linkages:
grouping, associating, placing new words into a context;
· applying images and sounds:
using imagery, semantic mapping, using keywords and representing sounds in
memory;
· reviewing well, in a
structured way;
· employing action: physical
response or sensation, using mechanical techniques.
The
techniques just mentioned can be used to greater advantage if we can diagnose
learning style preferences (visual, aural, kinesthetic, tactile) and make
students aware of different memory strategies.
Meaningful tasks however seem to offer
the best answer to vocabulary learning, as they rely on students’ experiences
and reality to facilitate learning. More meaningful tasks also require learners
to analyse and process language more deeply, which should help them retain
information in long-term memory.
Forgetting seems to be an inevitable
process, unless learners regularly use items they have learnt. Therefore,
recycling is vital, and ideally it should happen one or two days after the
initial input. After that, weekly or monthly tests can check on previously
taught items.
The
way students store the items learned can also contribute to their success or
failure in retrieving them when needed. Most learners simply list the items
learnt in chronological order, indicating meaning with translation. This system
is far from helpful, as items are de-contextualised, encouraging students to
over generalise usage of them. It does not allow for additions and refinements
nor indicates pronunciation.
Teachers can encourage learners to use
other methods, using topics and categories to organise a notebook, binder or
index cards. Meaning should be stored using English as much as possible, and
also giving indication for pronunciation. Diagrams and word trees can also be
used within this topic/categories organisation. The class as a whole can keep a
vocabulary box with cards, which can be used for revision/recycling regularly.
Organising this kind of storage system is
time-consuming and might not appeal to every learner. Therefore adapting their
chronological lists to include headings for topics and a more complete
definition of meaning would already be a step
forward.
2.2. DEALING
WITH MEANING
In
my opinion the most important aspect of vocabulary teaching for advanced
learners is to foster learner independence so that learners will be able to deal
with new lexis and expand their vocabulary beyond the end of the course.
Therefore guided discovery, contextual guesswork and using dictionaries should
be the main ways to deal with discovering meaning.
Guided discovery involve asking questions
or offering examples that guide students to guess meanings correctly. In this
way learners get involved in a process of semantic processing that helps
learning and retention.
Contextual guesswork means making use of
the context in which the word appears to derive an idea of its meaning, or in
some cases, guess from the word itself, as in words of Latin origin. Knowledge
of word formation, e.g. prefixes and suffixes, can also help guide students to
discover meaning. Teachers can help students with
specific techniques and practice in contextual guesswork, for example, the
understanding of discourse markers and identifying the function of the word in
the sentence (e.g. verb, adjective, noun). The latter is also very useful when
using dictionaries.
Students should start using EFL
dictionaries as early as possible, from Intermediate upwards. With adequate training, dictionaries are
an invaluable tool for learners, giving them independence from the teacher. As well as understanding meaning,
students are able to check pronunciation, the grammar of the word (e.g. verb
patterns, verb forms, plurality, comparatives, etc.), different spelling
(American versus British), style and register, as well as examples that
illustrate usage.
2.3. USING
LANGUAGE
Another strategy for advanced learners is
to turn their receptive vocabulary items into productive ones. In order to do
that, we need to refine their understanding of the item, exploring boundaries
between conceptual meaning, polysemy, synonymy, style, register, possible
collocations, etc., so that students are able to use the item accurately.
We
must take into account that a lexical item is most likely to be learned when a
learner feels a personal need to know it, or when there is a need to express
something to accomplish the learner’s own purposes. Therefore, it means that the
decision to incorporate a word in ones productive vocabulary is entirely
personal and varies according to each student’s motivation and
needs.
Logically, production will depend on
motivation, and this is what teachers should aim at promoting, based on their
awareness of students needs and preferences. Task-based learning should help
teachers to provide authentic, meaningful tasks in which students engage to
achieve a concrete output, using appropriate language for the context.
2.4. THE
LEXICAL APPROACH
We
could not talk about vocabulary teaching nowadays without mentioning Lewis
(1993), whose controversial, thought-provoking ideas have been shaking the ELT
world since its publication. We do not intend to offer a complete review of his
work, but rather mention some of his contributions that in our opinion can be
readily used in the classroom.
His
most important contribution was to highlight the importance of vocabulary as
being basic to communication. We do
agree that if learners do not recognise the meaning of keywords they will be
unable to participate in the conversation, even if they know the morphology and
syntax. On the other hand, we believe that grammar is equally important in
teaching, and therefore in our opinion, it is not the case to substitute grammar
teaching with vocabulary teaching, but that both should be present in teaching a
foreign language.
Lewis himself insists that his lexical
approach is not simply a shift of emphasis from grammar to vocabulary teaching,
as ‘language consists not of traditional grammar and vocabulary, but often of
multi-word prefabricated chunks’(Lewis, 1997). Chunks include collocations,
fixed and semi-fixed expressions and idioms, and according to him, occupy a
crucial role in facilitating language production, being the key to
fluency.
An
explanation for native speakers’ fluency is that vocabulary is not stored only
as individual words, but also as parts of phrases and larger chunks, which can
be retrieved from memory as a whole, reducing processing difficulties. On the
other hand, learners who only learn individual words will need a lot more time
and effort to express themselves.
Consequently, it is essential to make
students aware of chunks, giving them opportunities to identify, organise and
record these. Identifying chunks is not always easy, and at least in the
beginning, students need a lot of guidance.
Hill (1999) explains that most learners
with ‘good vocabularies’ have problems with fluency because their ‘collocational
competence’ is very limited, and that, especially from Intermediate level, we
should aim at increasing their collocational competence with the vocabulary they
have already got. For Advance learners he also suggests building on what they
already know, using better strategies and increasing the number of items they
meet outside the classroom.
The
idea of what it is to ‘know’ a word is also enriched with the collocational
component. According to Lewis (1993) ‘being able to use a word involves
mastering its collocational range and restrictions on that range’. I can say
that using all the opportunities to teach chunks rather than isolated words is a
feasible idea that has been working well in my classes, and which is fortunately
coming up in new coursebooks we are using. However, both teachers and learners
need awareness raising activities to be able to identify multi-word
chunks.
Apart from identifying chunks, it is
important to establish clear ways of organising and recording vocabulary.
According to Lewis (1993), ‘language should be recorded together which
characteristically occurs together’, which means not in a linear, alphabetical
order, but in collocation tables, mind-maps, word trees, for example. He also
suggests the recording of whole sentences, to help contextualization, and that
storage of items is highly personal, depending on each student’s
needs.
We
have already mentioned the use of dictionaries as a way to discover meaning and
foster learner independence. Lewis
extends the use of dictionaries to focus on word grammar and collocation range,
although most dictionaries are rather limited in
these.
Lewis also defends the use of ‘real’ or
‘authentic’ material from the early stages of learning, because ‘acquisition is
facilitated by material which is only partly understood’ (Lewis, 1993, p. 186).
Although he does not supply evidence for this, I agree that students need to be
given tasks they can accomplish without understanding everything from a given
text, because this is what they will need as users of the language. He also
suggests that it is better to work intensively with short extracts of authentic
material, so they are not too daunting for students and can be explored for
collocations.
Finally, the Lexical Approach and
Task-Based Learning have some common principles, which have been influencing
foreign language teaching. Both approaches regard intensive, roughly-tuned input
as essential for acquisition, and maintain that successful communication is more
important than the production of accurate sentences. We certainly agree with
these principles and have tried to use them in our
class.
3. RATIONALE OF
THE LESSON
We
believe that the Lexical Approach has much to offer in the area of vocabulary
teaching, and therefore we have tried to plan a lesson that is based on its main
concepts, specially exploring the use of collocations.
3.1 CHOICE OF MATERIAL
As
both the Task-based and the Lexical approach suggest, we wanted to use authentic
material to expose our students to rich, contextualised, naturally-occurring
language.
For
the topic of holidays we chose a big number of holiday brochures (about twenty
five) and read them through, trying to notice recurrent patterns of lexis.
Confirming what Hill (1999) affirmed, this analysis showed us a large number of
collocations, specially adjective + noun
ones, and that some were extremely common, such as golden sandy beaches, rolling countryside
and others.
We
did not want to overload students with much reading, which would detract them
from the main task of working with vocabulary, and therefore we selected
twenty-one short yet meaningful extracts in which common collocations
appeared.
3.2. NOTICING COLLOCATIONS AND DEALING
WITH MEANING
Although the extracts are authentic, we
do not think students will have many problems in understanding most of the
collocations, as they contain vocabulary which they probably know receptively.
This again should confirm the idea that students know individual words but lack
collocational competence.
We
are going to work as a whole class in step 5 to make students aware of the
collocations we will be focusing on, and hopefully this will enable students to
find other collocations. Regular awareness raising activities like this should
help students improve their collocational competence, and even fluency, as
discussed in part 2.4.
For
the few words that we predict students will not fully understand meaning of, or
are not sure how they are pronounced, we are going to ask them to look these up
in monolingual dictionaries. As we said in part 2.2., dictionaries are a vital
tool for Advanced learners, and so is contextual guesswork, which we are going
to encourage before they look the words up. We are also going to ask students to
notice examples given in the dictionary, observing and recording other possible
collocations of the words, as suggested by Lewis.
We
have also taken into account the importance of recording the vocabulary observed
during the class. The list that students will produce in step 9, to prepare for
the final task, is also a way of recording vocabulary in an organised,
personalised and meaningful way, as suggested by Lewis in part
2.4.
3.3. GROUP WORK
Working in groups help fostering learning
independence, and specially in vocabulary work, learners can exchange knowledge,
asking others to explain unknown items.
We
also hope that group work will be a motivating factor, as students talk about
places they have been on holiday to, trying to remember details together,
exchanging impressions and even good memories!
3.4. CHOICE OF TASK
As
we said earlier in part 2.3, we find it vital that students are given
opportunities to use the language they are learning in a realistic context.
Therefore, we have devised the final task to meet this
principle.
Writing a leaflet is a possible task in
the Cambridge Certificate of Advanced English, which these students are
preparing for. It is also a relevant, real life task that we expect will
interest students. I always like to mention that the standard of leaflets
written in English in Brazil is very poor, and that they could do a much better
job.
We
expect that this writing should also enable students to use the vocabulary they
have studied in a realistic context, and that they could be motivated to learn
even more vocabulary they feel they need to accomplish the
task.
The
completion of the final task for homework will also help to reinforce and revise
the vocabulary learnt, giving students a better chance to store the items in
their long-term memory, as we mentioned in part 2.1.
We
are going to explain what the final task will be right after step 3, in which
they should notice what kind of text the extracts come from. By doing this we
want to motivate students to do the enabling tasks, mainly to show them the need
to learn new vocabulary.
As
this is a borrowed group, it might be the case the students are not yet familiar
with the leaflet format, in which case more input would be necessary before the
conclusion of the final task.
If
students are really interested in the task, this could be transformed into a
project, involving research and the production of a leaflet or web page in the
multi-media centre.
