THE ROLE OF FORMAL INSTRUCTION IN SECOND LANGUAGE ACQUISITION
THE ROLE OF FORMAL INSTRUCTION IN SECOND LANGUAGE ACQUISITION
Introduction
This
chapter looks at second language acquisition in a classroom setting. It
considers whether instruction makes a difference to SLA. This is an
important issue, because it addresses the question of the role played by
environmental factors in SLA. It is also an important educational
issue, as language pedagogy has traditionally operated on the assumption
that grammar can be taught.
Two board types of SLA can be identified according to the acquisition setting;
-
Naturalistic SLA.
-
Classroom SLA.
It was
pointed out that classroom discourse can be distorted, in comparisons to
naturally occurring discourse. An important question therefore is in
what ways this distortion, which is largely brought about by the attempt
to instruct rather than to converse, affects the route and rate of SLA
in the classroom. By considering how formal instruction affects SLA it
is possible to address the wider issue of the role environmental
factors.
In many
instructional methods an assumption is made that focusing on linguistic
form aids the acquisition or grammatical knowledge or to put it another
way, that raising the learner’s consciousness about the nature of target
language rules helps the learner to internalize them.
In the
case of deductive methods this is self-evidently the case. But it is
also true in ‘habbit methods’ methods such as audio-legal lingualism ,
as the purpose of the practice provided is to focus on specific
linguistic forms, which the learner is encouraged to induced and of
which ultimately he will form a more or less, conscious mental
representation.
Another
assumption of formal instruction is that the order in which grammatical
features are taught will govern the order in which they are learnt.
Language syllabuses are organized in such a way as to facilitate the
correlation between the teaching order and the learning order.
The
investigation of the role of formal instruction can be undertaken in two
ways. First, an answer to the question ‘Does formal instruction aid
SLA?’ can be sought. Secondly, the question ‘What kinds of formal
instruction facilitate SLA the most?’ can be tackled. In the first
question there is an assumption that all types of formal instructions
share certain basic premises and that it is, therefore possible to talk
generically of ‘ Formal instruction’. In the second question there is an
assumption that formal instruction in general is facilitative and that
the important issue is what is distinguishes the more successful from
the least successful types.
What the
different instructional methods had in common was a focus on form,
manifested, for instance, in the provision of feedback by the teacher
for correcting formal errors.
This
chapter has four sections. The first examines its effect on the route of
SLA. The secondly examine its effect on the rate/success of SLA. In the
third section, explanations of the result reported in the first two
sections will be reviewed. Finally, the conclusion briefly considers the
implications for both SLA theory and language pedagogy.
The effects of formal instruction on the route of SLA
The route
of SLA was considered in term of general sequence of development and
the order in which specific grammatical features were acquired. The
evidence for the reported universality of the sequence and the minor
differences in the order come from (1) morpheme studied (2) longitudinal
studies. These studies how ever were of either pure naturalistic SLA or
mixed SLA. The morpheme and longitudinal studies will again be
considerers separately.
Morpheme studies of classroom SLA
The
morpheme studies can be divided into two groups. In the first group are
five studies that investigated second language learners. In the other
group are four studies investigated foreign language learners
Perkins and Larsen freeman (1975) investigated the morpheme; they used two tasks to collect data;
-
A translation test.
-
A description task based on a non-dialogue film.
On (1)
the morpheme orders before and after instruction differed significantly,
but on (2) there was no significant difference. In other words, the
teaching and learning orders were different. Taken together, these
studies suggest but do not prove that formal instruction does not alter
the order of acquisition of grammatical morphemes when the learners is
engaged in language use and is focused on meaning.
This
general conclusion holds true irrespective of whether the learners are
children or adults and most interestingly, irrespective of whether the
learners are in foreign or second language environments. Formal
instruction appears, then to have only a negligible effect on the
morpheme order manifest in spontaneous language use. However, morpheme
orders measure accuracy rather than acquisition. In order to obtain a
more reliable picture of the effects of instruction on L2 development,
it is necessary to turn to the longitudinal studies of translation
structures.
Longitudinal studies of classroom CLA
Curiously
the case-study approach, so central to the methodological baggage of
first and second language acquisition researchers has not typically,
been thought sensible for learners in class. There are very few
longitudinal studies of classroom SLA. The three that will be discussed
here are Felix (1981), Ellis (1984a) and Schumann (1978b). The available
longitudinal evidence, therefore is even slighter that provided by the
morpheme studies. The general teaching method was a traditional
audio-lingual one, the grammatical structures that Felix report on are
negation, interrogation, sentence types, and pronoun. For each
structure, parallels were found between tutored and naturalistic SLA. In
a classroom where the instruction is very formal, learners are
constantly being forced to produce structures they are not ready for.
Felix suggests that they solve the problem that this poses for them in
one of two ways. Either they select random from the structures in their
repertoire, irrespective of syntactic or semantic appropriateness, or
they follow the same rules that characterize the early stages of
naturalistic language acquisition.
Ellis
examined negatives, interrogatives, and a number of verb phrase
morpheme. All of these structures were formally taught at one time. When
the communicative speech produced by the learners in the classroom was
analysed, it was shown to display a pattern of development more or less
identical to that observed in naturalistic SLA.
In
Schumann’s study a deliberate attempt was made to teach an adult L2
learner how to negate. This took place in the context of a longitudinal
study of what was otherwise naturalistic SLA. Prior to the instructional
experiment the learner’s negative utterances were collected, Schumann
concluded that the instruction influenced the learner’s production only
in test-like situations, while normal communication remained unaffected.
Taking these studies together, the following can be hypothesized:
-
Instruction does not circumvent the processes responsible for the sequence of development evident in transitional structures such as negatives an interrogative in naturalistic SLA.
-
When classroom learners are required to produce structures beyond their competence, idiosyncratic forms are likely to result.
-
The distorted input may prolong certain stages of development and slow down the emergence of some grammatical features.
-
Classroom learners are able to make use of knowledge acquired through formal instruction when they are focused on form.
Summary
Morpheme
studies and longitudinal studies of SLA together indicate that although
formal instruction may develop L2 knowledge, this knowledge manifests
itself in language use only where the learner is attending to form. It
does not, therefore, except in relatively minor ways, affect the natural
route of SLA which is evident in communicative speech. To use the
distinction between sequence and order of development, we can say that
the overall sequence of development is not affected by formal
instruction, while order of development is hardly disturbed either.
Formal instruction influences knowledge only at the careful end of the
interlanguage stylistic continuum, not the vernacular end. These
conclusions, however, are necessarily tentative, as there have been few
studies of classroom SLA, particularly longitudinal.
This
section has examined three theoretical positions which provide
explanations of why formal instruction does not affect the natural
sequence of SLA but does facilitate more rapid development. The non
interface position proposed by Krashen claims that ‘acquisition’ and
‘learning are separate. Because ‘acquisition’ is responsible for the
natural sequence, the ‘learning’ that results from formal instruction
cannot influence it. However, classroom provides opportunities for
comperhesinble input will accelerate ‘acquisition’.
The
interface position also posits two types of L2 knowledge, but Argus that
they are related so that ‘learning’ (or explicit knowledge) can become
‘acquisition’ (or implicit knowledge) when it is sufficiently practised.
A weaker version of this position, however, states that ‘learning’ does
not so much turn into ‘acquisition’ as facilitate it, when the learner
is ‘ready’. The variability position differs from the other two
positions in that it recognizes a variety of different ‘styles’, each
calling on knowledge types that vary in terms of analicity and
automaticity. Different task require the utilization of different kinds
of knowledge. Formal instruction contributes directly or indirectly to
there internalization of these different knowledge types and in so doing
enables the classroom learner to perform a wider range of linguistic
tasks than the naturalistic learner.
All there
positions provide arguments to account for the result of the empirical
research into the effect of formal instruction. These have been
considered in some detail. At the moment there is insufficient evidence
to make a clear choice between them. It is not likely that such evidence
will be forthcoming until there are more qualitative studies of the
classroom discourse that result from formal instruction and of the
linguistic development that such discourse induces.
Conclusion: some implications
This
chapter began by asserting that the investigation of the role played by
instruction in SLA was of significant for both SLA theory and language
pedagogy. In this conclusion I shall briefly consider some of the
implications.
In order
investigate the role of instruction in SLA, it is necessary to separate
out the effects that formal instruction has on the route of SLA and on
the rate/ successes of SLA. Where the route is concerned, formal
instruction appears to have no major effect. The overall sequence of
development associated with natural communicative language use does not
change, while only a few minor and temporary differences in the
acquisition of specific grammatical features have been observed. Thus
classroom SLA appears to involve the same processing strategies as
naturalistic SLA. Where the rate/ successes is concerned, instruction is
facilitative, although only in terms of relative utility, not in terms
of absolute effects. These results must be treated tentatively, as there
has been little empirical research.
There
different positions have been advanced to explain classroom SLA. The non
interface position, associated with Krashen (1982), distinguishes
‘acquired’ and ‘learnt’ knowledge and argues that they are separate.
This position offers a convincing explanation a why formal instruction
fails to influence the natural route of SLA, as this is a reflection of
‘acquisition’. The explanation it gives for why formal instruction aids
the rate/ successes of SLA is less clear. The interface position,
associated with Stevick (1980) and Sharwood-Smith (1981) among others,
claim that ’learnt’ or explicit knowledge can turn into ‘acquired’ or
implicit knowledge if there is enough practice. This position offers an
explanation for the rate/ successes finding, but it less convincing
about the route finding. The variability position, associated with
Tarone (1983) and Bialystok (1982), sees acquisition and language use
closely linked, such that different types of knowledge arise from and
are required for the performance of different language tasks.
This
position deals comfortably with the route finding (which occurs in a
particular kind performance) and can explain the rate/ success finding
if it is assumed that the learner who has access to a variety of
different knowledge types will outperform one who is more reliant on a
single kind of knowledge. However, it is premature to choose from among
these positions.
The study
of the role of instruction in SLA has implications for both SLA theory
and language pedagogy. In the case of the former, is stresses in
importance of act knowledge the structural properties of SLA which are
relatively immune to environmental differences. Where language pedagogy
is concerned, it sheds light on the code-communications dilemma,
although once again it would be premature to come to any firm
conclusions about the effectiveness of formal grammar teaching.
Second language acquisition theory
Studying
the role of instruction can throw on the contribution of environmental
factors in SLA. The classroom environment provides a different kind of
input from a natural setting. If environmental factors are important of
SLA, it might be predicted that (1) The acquisitional route in the two
setting will be different, and (2) the rate/ success of SLA in the two
setting will also differ. The research reviewed in the earlier sections
shows that (1) does not arise, while (2) may. The failure of the
classroom setting to influence the route of SLA can be explained in two
ways. First, it might be taken to show the real determinants of SLA are
learner-internal rather than environmental factors. That is, despite
differences in input, the L2 learner will follow the same developmental
path, because, although there are differences in the types of input to
be found in each setting, there are also similarities.
The
natural sequence is the product of one type language use-spontaneous
communication-which, although restricted in classroom context, does take
place. The first explanation follows a native’s interpretation. What is
the quite clear, whatever interpretation is adopted, is that SLA
possesses certain structural properties which are immune to
environmental differences in learnt in classroom and natural setting.
The effect of environmental factors appears to be restricted largely to
how quickly and how much of the L2 the learner acquires.
Language pedagogy
Looking
at instruction from the view point of the learner rather than the
teacher is salutary. It puts into perspective the widely held view that
if instruction is based on a sound syllabus and employs motivating
techniques, acquisition will result. Unless account is taken of the
structural properties of SLA, success is by no means certain.
Teacher
ought not to feel obligated to ensure that his teaching also follows it,
as it is far more important that the teacher works from a syllabus
which he finds logically acceptable. Brumfit argues that language
teaching will be most successful when it follows as well-worked out plan
which directs and organizes what the teacher does. The second reason
for reticence is that, although there is a fair degree of agreement
among SLA researches concerning what happens in SLA.
There is a
far less agreement about why it happens in the why it does. This has
been evident in the different positions adopted to explain the result of
research into the effects of formal instruction. Briefly outline what
attitude to the code-communication dilemma is held by protagonists of
each of the three positions considered in the previous section
-
The non-interface position.
Krashen
(1982) pays close attention to the role of grammar teaching in classroom
SLA. He sees two uses for it. First, it enables the monitor to function
by providing for ‘learning’. However, monitor use is restricted to
occasions when the learner has time to access his ‘learnt’ knowledge,
and is also restricted by the fact that only a small sub-section of
total rules of a L2 are ‘learnable’. The second use of grammar teaching
is to satisfy learners’ curiosity about the nature of the L2 grammatical
system ‘grammar appreciation’. The use of conscious grammar is limited,
therefore, that the role of teaching is to afford opportunities for
communications, rather than to draw attention to the L2 code.
Krashen (1981b) lists the defining characteristic of what he considers an effective pedagogical programme;
-
The classroom input must be comprehensible.
-
The programme must consist of ‘communicative activities’, as only these will ensure that he input is interesting and relevant.
-
There should be no attempt to follow a grammatically sequenced programme.
-
The input must be of sufficient quantity (hence importance of extensive reading).
-
The interface position
Where the
non-interface position emphasizes the importance of communication and
minimizes the importance of the code, the interface position asserts the
contribution of the code. Sharewoos-Smith (1981) sees grammar teaching
as a short cut to communicative ability. That is, the adult learner who
has his attention drawn to features of the code can practise these, both
in and out of the classroom, until he can use them subconsciously in
fluent communicative speech. Consciousness-raising, therefore, does not
require that the learner is able to verbalize the rules he has learnt.
For Sharwood-Smith, then, the important issue is not whether the code
should be taught, but in what way it should be taught.
-
The variability position
The
variability position stresses importance of matching the learning
process with the type of instruction. Instruction must consider the
specific goals of the learner and attempt to provide the appropriate
form of knowledge to achieve those goals. The ‘goals’ refer to the type
of language use that the learner needs (or wants) to engage in. if the
goal is to participate in natural conversation, the learner will need to
develop his vernacular style by acquiring L2 knowledge that is
automatic but unanalysed.
This can
be achieved directly by means of instruction that emphasizes
communication in the classroom. It may also be achieved indirectly by
teaching that focuses on the code, if there are also sufficient practice
opportunities to trigger the passage of knowledge from the careful to
the vernacular style.
